Known Traveler Number program: What is it, and should you get 1?

Editor's Note

When you travel, there are a few pieces of information you probably like to keep handy, including your frequent flyer number, your passport number and your trip confirmation number.

However, another number comes into play if you have TSA PreCheck or Global Entry : your Known Traveler Number. It's an important number that ensures access to the TSA PreCheck lanes .

Here's what to know about getting a KTN, how to find it and how to ensure it's attached to your flight reservations.

What is a Known Traveler Number?

A KTN is a nine-digit code each TSA PreCheck and Global Entry member receives from the U.S. Department of Homeland Security upon approval for one of those two programs. Members of a couple of other Trusted Traveler programs get a KTN as well.

The code may be a combination of both letters and numbers. It's your identification number that proves you're a member of one of these programs and shows that you are eligible to use the TSA PreCheck lanes at U.S. airports.

Travelers with a KTN have gone through an application and screening process , and they are known and recognized as travelers by the U.S. government.

Should you apply for a Known Traveler Number?

Getting a KTN is helpful for air travel because if you have one, it means you're a member of a program that gets you shorter wait times.

A KTN is your key to access the TSA PreCheck lanes. These lanes typically have shorter lines and allow members to undergo a less intrusive screening process than the standard lanes. About 99% of TSA PreCheck customers wait 10 minutes or less at security, according to the Transportation Security Administration.

There are several ways to get a KTN through different Trusted Traveler programs run by the DHS. Each program requires travelers to submit an application and go through an interview process. Those interviews generally occur in person at enrollment centers for first-time applicants, with many enrollment centers located at airports. The government is allowing virtual interviews for certain applicants, often those seeking to renew their membership.

Each program that provides travelers with a KTN has a fee, and memberships in all programs are valid for five years. Many credit cards also offer application fee credits for Global Entry or TSA PreCheck .

TSA PreCheck

If you've applied for TSA PreCheck, gone through the screening process and received confirmation of your approval into the program, you'll receive a KTN from the government.

TSA PreCheck offers a fast-tracked security experience for its members. When going through the TSA PreCheck lanes, you generally won't have to remove your shoes, take laptops or liquids out of your bag, or go through the full-body scanner.

The application fee is $78 for first-time applicants.

Global Entry

If you've received your TSA PreCheck membership by applying for Global Entry, you'll receive your KTN through your Global Entry membership.

Global Entry is a U.S. Customs and Border Protection program that allows travelers designated as low-risk by the U.S. government to use faster customs lines when returning to the U.S. from abroad. Members also get access to TSA PreCheck.

The fee for an application to this program is $100.

If you're planning to travel internationally and within the U.S. multiple times in the next five years, Global Entry is probably your best bet since it gets you expedited screening both at customs and at TSA checkpoints for only $22 more than a standard TSA PreCheck membership.

Nexus and SENTRI

The DHS has two other Trusted Traveler programs for travelers entering the U.S. from Canada and/or Mexico. Nexus and SENTRI also provide members with TSA PreCheck access and, thus, a KTN.

Nexus allows pre-screened travelers to use expedited processing when entering the U.S. from Canada by air or land. The fee for this program's application is $50.

SENTRI allows pre-screened travelers expedited entry into the U.S. from Canada and Mexico by air, land or sea. The application fee for this program is $122.25.

How do you add a Known Traveler Number to your travel bookings?

Once approved for TSA PreCheck, Global Entry, Nexus or SENTRI, you'll have to follow one additional step to ensure "TSA PreCheck" is printed on your boarding pass: You have to attach your number to your airline profile.

If you're just looking to attach your number to a single reservation, you can typically do this when filling out your personal information at checkout when booking a flight. However, we recommend always flying with a frequent flyer account to earn miles .

If you have a frequent flyer account, you can attach your KTN right to the personal information section of your airline profile. Once you do this, your KTN should be automatically added to each booking you make with that airline, as you include your frequent flyer number on the reservation. You typically can add your KTN to an existing reservation, too.

What to do if you forgot to add a KTN to your flight

If you already booked a flight and forgot to add your Known Traveler Number to your reservation, don't fret. You should be able to easily pull up your reservation and add your KTN.

Go to the airline's website or mobile app. Pull up your reservation using the confirmation number (or record locator) the airline gave you when you booked your trip. Then, go to the traveler information section. There should be a line that says "Known Traveler Number," "KTN" or "Secure Traveler Information." That's where you put your KTN.

If you've already checked in for your flight and downloaded your boarding pass, you may need to re-download the boarding pass to see "TSA PreCheck" appear.

Where can you find your Known Traveler Number?

The time when you'll most likely need your KTN handy is when booking a flight or updating your airline profile. This goes for new members of TSA PreCheck, Global Entry, SENTRI or Nexus, as well as existing members who might be flying with an airline for the first time since joining one of those programs.

With all the numbers, passwords and accounts we have to keep track of in our lives, it's easy to lose your KTN ... and most of us probably don't know our number by heart. Fortunately, there are a few ways to locate it.

If you're a standard TSA PreCheck member looking to track down your number, you can use this page from the DHS to put in your personal information and look up your number.

If you received your KTN through the Global Entry program, you have a couple of options. If you have your physical Global Entry card, check the backside. Your nine-digit "PASSID" is your KTN; it may start with "15," "98" or "99."

Another way to locate your Known Traveler Number is to log in to your Global Entry or other Trusted Traveler Program account. There, you should be able to see which program you're enrolled in, as well as your membership number/PASSID, which, again, is your KTN. You should also be able to see when your membership expires.

An additional option for tracking down your number is to check your frequent flyer account for an airline you've recently flown with. If your membership in one of the Trusted Traveler programs is active and you've used TSA PreCheck before, odds are your KTN is on file with one or more airlines you regularly fly.

For this option, you'll need to go to your airline profile. If your KTN is in your profile, you should see it listed under your personal information.

Bottom line

A Known Traveler Number is a code that gets you into the TSA PreCheck lane. It's how the airline and government recognize a trusted traveler who is a member of TSA PreCheck, Global Entry or other similar programs.

Keep your number handy and add it to your airline profile. If you're not a member, consider enrolling in one of these programs that gives you a KTN and makes your trip through the airport less of a hassle.

Known Traveler Number Guide: (How to Lookup, Global Entry, Pre-Check) [2023]

This comprehensive article will tell you everything you need to know about your Known Traveler Number.

I’ll cover how you can get one and the best way to do that with programs like TSA Pre-Check and Global Entry. I’ll show you how to look-up your Known Traveler Number and add it to your travel itineraries with airlines like United, Southwest, and Delta.

Finally, I’ll explain the differences between a Known Traveler Number and a Redress Number.

Table of Contents

What is a Known Traveler Number?

A Known Traveler Number, also called your “KTN,” is a 9-digit number used to link your TSA Pre-Check enrollment to your travel itinerary in order to ensure that you can receive TSA Pre-Check benefits like expedited security screening.

This is the same number used for other trusted traveler programs, such as Global Entry, NEXUS, and SENTRI . However, for these latter programs, this number is known as your “PASSID.”

Tip: Use the free app WalletFlo to help you travel the world for free by finding the best travel credit cards and promotions!

Why do you want a Known Traveler Number?

With a Known Traveler Number, you can participate in TSA Pre-Check, which means you’ll be able to breeze through security at airports.

How do you get a Known Traveler Number?

You can get a Known Traveler Number by signing up, getting approved, and paying the fees for any of the following programs:

TSA Pre-Check

Global entry.

As already discussed, TSA Pre-Check will usually get you through airport security in a breeze.

You’ll usually get access to a priority security line which is often much shorter than the standard security line (though not always, unfortunately).

You’ll also be able to go through a less restrictive and invasive screening process. You often only have to pass through a traditional metal detector (as opposed to the full-body scanners) and you also get to enjoy the following benefits:

• Shoes can stay on
• Belt can stay on
• Light jackets can stay on
• Laptops allowed to stay in bag
• Liquids ( 3-1-1 Rule ) can stay in bag

This program costs $78 to enroll for five years and it does not require the extensive interview process that Global Entry requires. There are multiple ways to get TSA Pre-Check for free and you can read about those here.

Global Entry would be my preferred method for obtaining a Known Traveler Number. That’s because not only will you get TSA Pre-Check, but you’ll also get expedited entry at Customs and Immigration when making your way back into the US.

This program does require you to attend an interview to be approved but the interview process is not difficult at all . If you’ve got a clean criminal history and come prepared with your documents then you should pass the background check and interview without any issues at all.

In some cases this “interview” process will only take about five minutes total.

You might get asked some very basic questions like what countries you have visited and whether or not you have traveled for business or pleasure. It’s hardly anything close to an interrogation in most cases.

The hardest part is often scheduling the interview because availability can be limited and in some cases it might take weeks (or even months) to find an open slot.

Luckily, some airports offer interviews upon arriving from international locations. So if you have some international travel coming up, this can be one of the easiest ways to get approved for Global Entry.

There are many credit cards that come with a $100 statement credit for your Global Entry application fee, so it’s very easy to get this program for free. My personal recommendations for getting a $100 statement credit for your Global Entry/TSA Pre-Check is to go with the United Explorer Card. It has great perks and a low annual fee and you can read more about it here! 

Since you’ll get both TSA Pre-Check and expedited entry back into the US, I think Global Entry is the way to go for many people.

NEXUS is a joint program between the US and Canada that will grant pre-approved, low-risk travelers expedited entry into  both  Canada and the US. Specifically, membership in the NEXUS program allows you to reduce your wait times at designated ports of entry by:

• Using dedicated processing lanes at land border crossings
• Using NEXUS kiosks when entering Canada
• Using their card in dedicated SENTRI lanes along the U.S.-Mexico border
• Using Global Entry kioks when entering the United States, and
• Calling a marine telephone reporting center to report your arrival into the United States and Canada

You may also be granted access to the Canadian Air Transport Security Authority (CATSA) Security Line at some Canadian airports to expedite airport pre-boarding security screening. (This is like a Canadian version of TSA Pre-Check.)

Just like Global Entry, NEXUS will require you to clear a background check. The difference is that this background check also is submitted to Canadian authorities, such as the  Canadian Security Intelligence Service (CSIS), Royal Canadian Mounted Police (RCMP).

One of the major draws to the NEXUS program is that the  application fee is only $50 . This is surprising since NEXUS comes with both Global Entry and TSA Pre-Check, which cost $100 and $85 respectively. For people who live near or travel between the US/Canada border, NEXUS is an especially attractive bargain.

The Secure Electronic Network for Travelers Rapid Inspection (SENTRI) is a U.S. Customs and Border Protection (CBP) program that allows expedited clearance for pre-approved, low-risk travelers upon arrival in the United States.

You can enter the United States by using dedicated primary lanes into the United States at Southern land border ports so this is a program you might be interested in if you’re traveling between the US and Mexico a lot.

You might be a little overwhelmed with all of the different Trusted Traveler programs and perhaps you’re not sure which program you should sign-up for.

If that’s the case you can check out this TSA tool  which can help you narrow down what program is most ideal for you based on your citizenship, number of flights, and travel destinations.

Other related travel programs

CLEAR is a privately owned service offered to passengers that allows them to bypass the lines going into airport security, whether you are going into the standard security line or the TSA Pre-Check line.

In order to use it you find the CLEAR line leading to security which should have little to no line and then you simply scan your boarding pass and biometric data and then you’re off to the races and able to skip whatever line you would have been waiting on. You don’t even have to show your ID.

CLEAR can be great for frequent flyers in busy airports but it’s not cheap at $179 per year (though cheaper promos are often available). This program does not require you to have a Known Traveler Number.

Mobile Passport

Launched in the fall of 2014, Mobile Passport Control is an app, developed by Airside Mobile and Airports Council International-North America in partnerships with CBP, that you can download to use in order to expedite your entry into the US. It’s available in the  Apple App Store  and  Google Play .

It’s free to use and can be just about as good as Global Entry at some airports, though I’d still take Global Entry over Mobile Passport.

That’s because Global Entry gets you Pre-Check and also allows you to get through customs AND immigration while Mobile Passport often only get your priority access through immigration. This program also does not require you to have a Known Traveler Number.

Adding a Known Traveler Number

Once you have your Known Traveler Number, you’re going to need to add that number to your travel profiles for the various airlines so that your Known Traveler Number will automatically show up in your itineraries.

However, you should note that your Known Traveler Number will NOT automatically show up in all of your travel  itineraries.

Many people assume that once they add their Known Traveler Number to their profile, it will always show up but that’s not the case. So you always need to double check that your KTN was added.

Below, you can see how to add your Known Traveler Number to some of the major airlines. For whatever reason, it is not always the easiest thing to do since you often have to click around a lot.

Usually you can find where to input it if you just look for your profile and a button allowing you to edit your profile, but the steps below should help you locate this.

American Airlines

Sign in to your American Airlines account and then click on your name at the top of the page. Then click on “your account.” Next, click on “edit account” and then click on “Information and password.” Scroll down and then under “Secure traveler,” you will see where to input your Known Traveler Number.

Sign in and click on “My Account” and then scroll to “My Preferences” to change your personal details within your profile information.

Sign in and click on Profile and Preferences and then click on “Travel identification documents” and then you’ll see the area to enter it in below.

Go to the Delta website and log-in and then proceed to My Delta -> My Profile -> Basic Info. You’ll then see a field where you can input your Known Traveler Number.

First, sign in to your JetBlue account. Click on the arrow in the upper right corner by your name and then click on “Edit profile.” Scroll down and you will see where to input your information.

Hawaiian Airlines

First, sign in to your Hawaiian Airlines account. Go to My Account and under that click on “Profile & Settings.” Click on the travel tab and you will see where to input your information.

Travel portals and OTAs

Most online travel agencies (like Expedia) will allow you to enter in your Known Traveler Number into your profile which should populate into your itinerary when you make a booking.

But since you’re dealing with a third party, you should always verify that your number was properly included in your booking.

Add Known Traveler Number after booking?

If you add your Known Traveler Number to your profile after you make a flight reservation, there’s a good chance that your flight itinerary is not linked to your Known Traveler Number and you won’t get TSA Pre-Check. 

In that case, you should be able to call up the airline and request for them to input your number into your itinerary.

You could also just wait until you arrive at the check-in desk for baggage and request for your Known Traveler Number to be added to your boarding pass.

Also, sometimes you’ll have to re-add your Known Traveler Number to specific itineraries. It’s not always clear why this happens but sometimes you’ll just have to do it.

If you ever are given a boarding pass without TSA Pre-Check on it and you know you have a TSA Pre-Check membership, simply approach an agent at the check-in desk and tell them you would like to add your Known Traveler Number.

It’s usually no problem for them to do this and they can re-issue you a boarding pass in a couple of seconds that has TSA Pre-Check.

For the reasons above, I highly recommend that you keep your Known Traveler Number somewhere easily retrievable like in your smart phone in a folder or app that you won’t forget about and can quickly pull up.

Where can I look up and find my Known Traveler Number?

If you are a member of the TSA Pre-Check Application Program you can, look up your KTN online .

If you are a member of another trusted traveler program, such as Global Entry, NEXUS, or SENTRI,  log on to the Trusted Traveler Program website  to obtain your PASSID, which once again is the same as your KTN.

You’ll find it right under “Program Memberships.”

You can also check the back of your trusted traveler cards for your PASSID. Note that TSA does not issue an ID card like Global Entry, NEXUS, and SENTRI do.

Related: Can You Get Through TSA and Fly with No ID?

What is a redress number?

You might also be wondering about a redress number since that field often shows up near where you input your Known Traveler Number.

A redress number is the record identifier for people who apply for redress through the DHS Travel Redress Inquiry Program (DHS TRIP) .

“DHS TRIP is for travelers who have been repeatedly identified for additional screening and who want to file an inquiry to have erroneous information corrected in DHS systems.”

For example, someone might share the same name as another person on a no-fly list and that might bring up a red flag every single time this unfortunate traveler attempts to board a plane.

The redress number will help those people avoid additional searches, pat downs, and questioning in the future.

So in case you were wondering a redress number really has nothing to do with your Known Traveler Number.

Known Traveler Number for Military members

If you are a member of the military, you can utilize TSA Pre-Check for free.

Members of the U.S. Armed Forces can get expedited screening including those serving in the U.S. Coast Guard, Reserves, and National Guard.

This can be done by using the official Department of Defense (DoD) identification number when making flight reservations. Your 10-digit DoD ID number is located on the back of your Combined Access Card ID and it is not the same as your SSN. Read more about how to utilize this benefit here.

TSA Pre-Check vs Global Entry

Now that you’re aware of all of the benefits you might be wondering whether or not you should choose TSA Pre-Check or Global Entry.

The answer to this question depends a lot on your personal preferences.

If you are only going to be traveling within the US then your need for Global Entry will be nearly zero.

In that case, getting TSA Pre-Check should be just fine. The only drawback to that is that if an unexpected trip comes up you’ll lose out on the benefit you could have had with Global Entry.

On the other hand, if you’re going to be traveling internationally then you might want to think about Global Entry since it will save you a lot of time getting back into the country.

The two drawbacks to Global Entry are that it requires you to attend an interview and that the background check can be tough to clear if you have anything on your record like a DWI, DUI, etc.

Known Traveler Number FAQ

The easiest way would be to get approved for TSA Pre-Check .

No, you do not need a Known Traveler Number for CLEAR?

At the time of booking, you will typically see a field where you can enter your Known Traveler Number. In addition, you can add your Known Traveler Number to your frequent flyer profile. If you are at the airport, you can also ask an agent to add your Known Traveler Number to your boarding pass.

There is no practical difference and these are essentially the same.

As you can see, getting a Known Traveler Number can be very easy and can even be done for free with the right credit card.

I recommend going with a program like Global Entry to get your PASSID/Known Traveler Number and using a credit card with a $100 credit for Global Entry.

If you always keep your Known Traveler Number with you at all times you’ll be able to add it to your boarding pass when needed and there shouldn’t be any major issues.

I only travel to the States. Which one should I apply. I read and I see so many type to apply. Quite confusing. Truly appreciate if you can advise . Thank you Regards Teresa

If you don’t travel outside the US, TSA Pre-Check is a solid option.

How to Find Your KTN (Plus How to Enroll in or Renew PreCheck)

Last Updated: February 18, 2024 Fact Checked

Finding Your KTN

Enrolling in a trusted traveler program, renewing your tsa precheck authorization, expert q&a.

TSA PreCheck makes it easy for you to breeze through airport security without having to take off your shoes, belt, or jacket. But to access those PreCheck lanes, you need to enroll in the service and provide your PreCheck number—called a Known Traveler Number (KTN)—to the airline when you book your flight. If you've forgotten your KTN, the easiest way to find it is to check the TSA Enrollment website.

Things You Should Know

• Look for your KTN on official sources, such as your approval letter, or the TSA Enrollment website , if you're a US citizen.
• Use the PASSID on your membership card as your KTN if you're enrolled in the Global Entry, NEXUS, or SENTRI programs.
• Enroll in Precheck programs online to get a KTN. Schedule an in-person appointment, supply the required documents, and pay the application fee for approval.
• Check your TSA Precheck status and fill out the renewal application online within 6 months before it expires so it's continuously active.

• Your PASSID is a 9-digit number that usually starts with 15, 98, or 99.
• If you previously enrolled in TSA PreCheck directly, but then enrolled in Global Entry, NEXUS, or SENTRI later, use the PASSID associated with the later program as your KTN—it supersedes your previous enrollment.

• This receipt isn't the same as your approval letter. Your approval letter was mailed to you after your Enrollment Center appointment and has your KTN on it. Your UE ID and your KTN are two different things.

• The TSA also has an online form , but you'll probably get a quicker resolution by calling.

• TSA PreCheck : access to PreCheck lanes for airport departures; US citizens and lawful permanent residents are eligible; $78 for 5 years
• Global Entry : entry to the US from international destinations by air, land, or sea; access to PreCheck lanes for airport departures; US citizens, lawful permanent residents, and select foreign nationals are eligible; $100 for 5 years
• NEXUS : entry to the US from Canada by air, land, or sea; includes access to PreCheck lanes for airport departures for US citizens and lawful permanent residents as well as Canadian citizens; US citizens and permanent residents, Canadian citizens and permanent residents, and Mexican nationals are eligible; $50 for 5 years
• SENTRI : entry to the US from Canada and Mexico by air or land; includes access to PreCheck lanes for airport departures for US citizens and lawful permanent residents; US citizens and permanent residents, as well as all foreign nationals, are eligible; $122.25 for 5 years

• If you'd rather apply in person, enter your ZIP code in the TSA Enrollment Center locator to find the nearest Enrollment Center.

• If you need to reschedule your appointment, you can do that from the TSA Enrollment website as well. The Enrollment Centers do take walk-ins, although you may have to wait a while, especially during peak hours.

• List A : unexpired passport book or card, permanent resident card, unexpired US enhanced driver's license or enhanced state-issued ID
• List B : unexpired driver's license or state ID, unexpired US military ID, expired passport within 12 months of expiration, US birth certificate, US certificate of naturalization

• Many credit cards help offset or even cover the cost of TSA PreCheck membership as a benefit to customers—especially cards with travel or airline miles incentives. Contact your credit card company to see if this is a perk for you.

• The representative who fingerprints you will give you your receipt, which includes your Universal Enrollment ID (UE ID). Hang on to this! You'll need it to look up your KTN online.

• If you fly with the same airline frequently, save your KTN with your customer profile information on the airline's website so it'll auto-fill on future reservations. Thanks Helpful 0 Not Helpful 0

TSA PreCheck®

What is tsa precheck ® .

The TSA PreCheck ® program expedites traveler screening through participating TSA security checkpoints (for a complete list of participating airports, visit the TSA PreCheck® Airports and Airlines page 1-866-289-9673 -->). No need to remove shoes, belts, 3-1-1 liquids, laptops, or light jackets.

Are You Eligible?

U.S. citizens, U.S. lawful permanent residents and citizens of partner countries enrolled in Global Entry , NEXUS or SENTRI are eligible to participate in TSA PreCheck ® , as well as Canadian citizens who are members of NEXUS.

How It Works

If you are an eligible Global Entry, NEXUS or SENTRI member, enter your membership number (PASS ID) in the “Known Traveler Number” field when booking reservations, or enter it into your frequent flyer profile with the airline. The membership number enables Transportation Security Administration’s (TSA) Secure Flight System to verify that you are a legitimate CBP Trusted Traveler and eligible to participate in TSA PreCheck ® .

Where You Can Find Your Membership Number

You can find your Trusted Traveler member number by logging into your Trusted Traveler Programs (TTP) account. Your membership number is listed toward the bottom of the page. Your membership number is also located on the back of your Trusted Traveler card in the upper-left corner.

If you’re new to TSA PreCheck or Global Entry, you may be wondering what a Known Traveler Number (KTN) is, how it works, and why there’s a KTN box when booking flights, but there isn’t one for your TSA PreCheck or Global Entry number. Here’s what you should know about your KTN.

What Is a Known Traveler Number?

Your Known Traveler Number is your membership number with a Trusted Traveler Program. This number is what allows you to access TSA PreCheck security lanes and Global Entry lanes (depending on which Trusted Traveler Program you join).

How To Get a Known Traveler Number

To acquire a Known Traveler Number, you must participate in one of the Trusted Traveler Programs. These are:

• Global Entry
• TSA PreCheck

Global Entry and TSA PreCheck are by far the most popular options in the U.S. The NEXUS and SENTRI programs also provide a Known Traveler Number, though these programs are much less commonly used in the U.S.

Credit Cards That Reimburse for Global Entry, TSA PreCheck, and/or NEXUS Application Fees

Many premium credit cards will reimburse you for the application fee for either Global Entry or TSA PreCheck (including American Express, Capital One, Chase, and Citi, which all provide cards that offer an application fee reimbursement).

If your priority is earning tons of valuable (and transferable!) points, you might choose the Chase Sapphire Reserve card . It earns 5x points on air travel and 10x points on hotels and car rentals when you purchase travel through Chase Travel, 10x points on Lyft (through March 2025), 3x points on all other travel, and it comes with a Priority Pass Select membership for lounge access.

Cardholders also receive elite status with both Hilton Honors and Marriott Bonvoy upon enrollment. To top it off, you’ll earn 5x Membership Rewards points when booking flights directly with an airline.

And for travelers who value simplicity in earning and redeeming their rewards along with a reasonable annual fee, consider the Capital One Venture X card . It earns 2x Capital One miles on all purchases and comes with the lowest annual fee among the most popular premium credit cards.

Whichever card you choose, all you have to do is use it to pay for the Global Entry or TSA PreCheck application fee, and you’ll automatically be reimbursed.

How To Find Your Known Traveler Number

Hot Tip: You can find your PASSID  (also known as your Known Traveler Number) on the back of your Global Entry, NEXUS, or SENTRI card.

If you only have TSA PreCheck, log in to the Trusted Traveler Program website to access your PASSID/Known Traveler Number. If you lose your Global Entry, NEXUS, or SENTRI card, you can use the Trusted Traveler Program site to find the number.

How To Add Your Known Traveler Number to Bookings

While it might not be apparent at first, you’ll be happy to know that your TSA PreCheck or Global Entry number is, in fact, your Known Traveler Number. Simply enter your Known Traveler Number in the appropriate field when booking your flight. This can also be done later — even at the check-in desk at the airport.

The vast majority of the time, you do not need to carry your Global Entry card to access the airport’s TSA PreCheck or Global Entry lanes. That said, there have been some recent reports of travelers being asked to show their physical card. This appears to happen most at airports that allow travelers with Global Entry to preclear security, especially for flights departing from Canada. It also may happen when entering the U.S. by car via NEXUS or SENTRI lanes.

Hot Tip:  Unlike when returning from most countries, if you want to access Global Entry lanes when returning from Canada, you will need your physical Global Entry card with you.

Global Entry or TSA PreCheck: Which One Is Right for You?

As anyone who’s been through airport security knows, it can be a frustrating hassle. To expedite the screening process  at many U.S. airports, TSA PreCheck access provides a much better experience. If you are returning to the U.S. from an international destination, Global Entry can make getting through customs a breeze.

If you mainly travel within the U.S., you might think that you only need to get TSA PreCheck — this is understandable, considering the fee is $78 compared to $100 for Global Entry.

However, a Global Entry membership also provides access to TSA PreCheck. When you account for the application fee reimbursement offered by several credit cards, why wouldn’t you go ahead and get Global Entry? With the right card, the impact on your wallet is the same — neither should cost you a dime!

By getting Global Entry, you can enjoy a quicker security experience when boarding flights in the U.S. If you decide to travel abroad, you can take comfort in the fact that returning to the U.S. will be easy.

Hot Tip:  If you have additional questions, don’t miss our piece on the top Global Entry FAQs and TSA PreCheck FAQs . 

Final Thoughts

Airports are becoming busier by the year, so having access to TSA PreCheck and Global Entry is vital for quicker and smoother security screenings. With so many credit cards offering to reimburse you for the application fee, there is no excuse not to have a Known Traveler Number.

Whether you get TSA PreCheck or Global Entry, you’ll be all set for a better airport experience — just enter your PASSID/Known Traveler Number when booking your flight.

How to get TSA PreCheck

How to add tsa precheck to american airlines, how to add tsa precheck to delta air lines, how to add tsa precheck to southwest airlines, how to add tsa precheck to united airlines, do you get a known traveler number with global entry, key takeaways for adding tsa precheck to your flights.

Traveling through airport security can be a hassle. TSA PreCheck is a membership program offered through the Transportation Security Administration. With it, travelers get access to an expedited screening lane at participating airports.

Unlike travelers in the standard screening lane, those with TSA PreCheck can keep their shoes, belts, and light jackets on. Plus, they can leave electronics and and 3-1-1 liquids in carry-on bags during screening.

Access to the TSA PreCheck line is only granted if you have a TSA PreCheck logo on your boarding pass indicating that you're clear for access. That means you're first have to apply for TSA PreCheck . And once you have it, you'll have to submit your TSA PreCheck information to your airline at the booking stage.

But if you forgot — or just didn't have a TSA PreCheck number at the time of booking — no worries. You can add TSA PreCheck to your airline ticket after the fact. Here's your ultimate guide to adding TSA PreCheck to your airline ticket, including adding TSA PreCheck after booking:

NerdWallet has spelled out the specific steps for adding PreCheck to your reservation on four major airlines — American Airlines, Delta Air Lines, Southwest Airlines and United Airlines — but the process is largely similar no matter what airline you fly.

To apply for TSA PreCheck, you'll pay a fee, submit personal information for a background check and attend an in-person interview. The application fee is $78, and membership is good for five years, which breaks down to $15.60 per year.

However, many travel credit cards reimburse the application fee simply for charging the application fee to that charge.

After the initial application fee to join the program, TSA PreCheck renewal — which is every five years to continue membership — costs $70 if completed online.

WANT TSA PRECHECK FOR FREE?

A number of popular travel credit cards reimburse you for the application fee for trusted traveler programs like TSA PreCheck and Global Entry. Among them:

on Chase's website

on Bank of America's website

$0 intro for the first year, then $95 .

Statement credit of up to $100 as reimbursement when you charge the application fee for TSA PreCheck, Global Entry or NEXUS to the card. Available once every 4 years.

Statement credit of up to $100 as reimbursement when you charge the application fee for TSA PreCheck or Global Entry to the card. Available once every 4 years.

If your credit card offers reimbursement for the application fee for programs like TSA PreCheck or Global Entry, you must pay the fee with the card. You cannot submit a claim for reimbursement if you paid with some other method. Reimbursement will usually appear as a statement credit in your account within two months.

Cards typically offer reimbursement of only one fee once every four to five years. Check the terms and conditions of your card for the specific rules that apply. Note also that these cards only reimburse the application fee for a trusted traveler program. They don't automatically enroll you in the program or guarantee that you'll be accepted by the program. You still have to apply and go through the required screening, which in the case of TSA PreCheck and Global Entry includes an in-person appointment.

» SEE the best credit cards that pay for TSA PreCheck and Global Entry

Each airline has its own process for adding TSA PreCheck to a ticket or to your frequent flyer profile. But no matter the airline, you'll need your your Known Traveler Number (KTN) , which is the string of 9 or 10 digit-long numbers or letters unique to you if approved for TSA PreCheck. Note that adding your KTN to a ticket does not necessarily guarantee that it will be automatically applied to your next reservation.

That said, here's a step-by-step guide to how to add TSA PreCheck to American Airlines, Delta Air Lines, Southwest Airlines and United Airlines:

The easiest way to add PreCheck to a ticket on American Airlines is to update your AAdvantage profile with your Known Traveler Number (KTN).

Log in and go to "Your Account." Choose "Information and Password," then add your PreCheck number in the KTN field in the "Secure Traveler" section.

Adding your Known Traveler Number to new AA bookings

American Airlines allows travelers to add their TSA PreCheck number at booking. After you've chosen your flight date and time, you'll enter your passenger details.

If you're not logged in to your AAdvantage account, you'll need to enter your PreCheck number manually in the Known Traveler Number field.

Adding your TSA PreCheck Known Traveler Number , or KTN, to your airline loyalty program profile is your best choice. This will make it easier to include your KTN when booking through your account or when attaching your loyalty number to a reservation.

Global Entry is a membership program offered by the Department of Homeland Security that offers all the same benefits as TSA PreCheck — and then some.

With it, you get not just the TSA PreCheck benefits, but also faster entry at eligible U.S. Customs locations. It's slightly more expensive, but it can be worth it for folks who travel internationally. Plus many of the same credit cards that offer TSA PreCheck statement credits also reimburse Global Entry fees.

» Learn more: TSA PreCheck vs. Global Entry: which is better?

So how do you add your Global Entry information to your boarding pass? If you have a physical Global Entry card, you can find your Known Traveler Number on the back. From there, follow the steps above to share that number with your airline.

And no, even if you have a trusted traveler card, that alone won't grant you access to TSA PreCheck lanes. Instead, you must add your PASS ID number in the KTN field when making airline reservations to ensure the TSA PreCheck indicator appears on your boarding pass.

Once you're approved for TSA PreCheck, your benefits are not automatically applied to your flight reservations. You'll have to share your Known Traveler Number with your airline. Only then does the TSA PreCheck logo get added to your boarding pass so you can go through the speedy lane.

But even if you forgot to add your Known Traveler Number at booking, you're not out of luck. Yes, you can add TSA PreCheck to an existing reservation.

In most cases, you must update existing flights and your airline loyalty program profiles to be able to use the dedicated airport security lanes for PreCheck members.

And be sure to reprint boarding passes that don't have the "TSA PRE" stamp on them. If your boarding pass doesn't show your PreCheck status, you cannot use the TSA PreCheck security lanes.

For future reservations, log in to your airline account before booking your flight. Booking flights while logged in allows your PreCheck number to be added to reservations automatically. Or, you need to manually enter it yourself.

TSA PreCheck

Breeze through security.

TSA PreCheck ® is an expedited security program allowing eligible travelers to speed up their screening process at participating U.S. airports and for most international trips. To participate, you must apply and get approval from the Transportation Security Administration (TSA).

If you have TSA PreCheck, you’ll go through a dedicated screening lane at the airport where you may not need to remove your shoes, jacket, belt or laptop from your bag.

TSA PreCheck is also available if you’re enrolled in a Customs and Border Protection (CBP) Trusted Traveler program, including Global Entry, SENTRI, or NEXUS.

TSA Pre✓ Frequently Asked Questions

All passengers are eligible for expedited screening based on the secure flight passenger data (SFPD) that airlines are required to send to the TSA. Your profile information must match  exactly  what is listed on your TSA PreCheck/CBP Trusted Traveler application, driver’s license or other government-issued ID. The TSA is responsible for selecting participants on a per-flight-segment basis.  

You may increase your likelihood of being selected for PreCheck by signing up for a Customs and Border Protection (CBP) Trusted Traveler Program, including  Global Entry ,  SENTRI and  NEXUS , or by completing the PreCheck application program at a TSA Application Center.

Although participants in the CBP's Trusted Traveler Programs (Global Entry, NEXUS and SENTRI) and PreCheck application program are eligible for expedited screening, no one is guaranteed it.

Passengers can increase their likelihood of being selected by participating in a CBP Trusted Traveler Program or completing the PreCheck application program. Ensure that your profile information matches exactly what is listed on your passport, driver’s license or other government-issued ID, and PreCheck or CBP Trusted Traveler Program enrollment (including your middle name, if applicable).

Please note that the TSA, not Delta, selects individuals for expedited screening, and no individual can be guaranteed expedited screening.

Yes. Customers will be able to find the pre-notification indicator “TSA PRECHK” on the boarding pass underneath the passenger name field. On mobile boarding passes, the PreCheck logo will appear at the top-right corner above the barcode. Please note that if you are eligible for PreCheck the logo will appear on boarding passes throughout your itinerary, regardless of whether pre-screening lanes are available at your departure airport(s).

In addition, the eligibility status will be embedded in the barcode of the boarding pass. The TSA will scan the barcode at PreCheck checkpoints as a final determination of the customer’s eligibility status.

What Is a Known Traveler Number, and What Do You Do With One?

PhotoAlto / Getty Images

A Known Traveler Number (KTN), also called a Trusted Traveler Number, is a number issued by the US Transportation Security Administration ( TSA ), Department of Homeland Security (DHS), or Department of Defense (DoD). This number indicates that you have undergone a pre-flight background check or other screening before checking in for a flight.

Adding your Known Traveler Number to an airline reservation greatly increases your chances of being able to use the TSA's PreCheck security screening lanes at participating US airports. Your KTN also permits you to take advantage of expedited customs processing at select airports if you are a Global Entry member.

How Can I Get a Known Traveler Number?

The easiest way to get a KTN is to enroll in either the PreCheck or Global Entry program. If your application is approved, you will receive a KTN. A Global Entry KTN is linked to your passport information, while a PreCheck KTN is connected only to the personal information you supplied when you enrolled. Participating airlines may offer their frequent flyers PreCheck status. The airline will assign these travelers a KTN as part of that process. Active duty military personnel may use their DoD identification number as their KTN.

You may also apply for PreCheck or Global Entry on your own. US citizens pay $85 for a five-year PreCheck membership or $100 for a five-year Global Entry membership. (Tip: The nonrefundable fee must be paid whether or not you are approved for PreCheck or Global Entry.) If your travels frequently take you outside the US, Global Entry might be a better option for you because it not only provides you with a KTN but also gives you access to faster customs processing access at certain airports.

How Do I Use My Known Traveler Number?

If you received your KTN through the TSA's PreCheck program, you should add it to your reservation record every time you book a flight on a participating airline. If you make a flight reservation through a travel agent, give the agent your KTN. You can also add the KTN yourself if you reserve your flight online or by telephone. 

Participating airlines, as of this writing, include:

• Alaska Airlines
• All Nippon Airways
• Allegiant Air
• American Airlines
• Aruba Airlines
• Asiana Airlines
• Austrian Airlines
• Azul Airlines
• Boutique Airlines
• British Airways
• Brussels Airlines
• Cathay Pacific Airways
• China Airlines
• Condor Airlines
• Contour Aviation
• Copa Airlines
• Delta Air Lines
• Eastern Airlines
• Edelweiss Air
• Elite Airways
• Etihad Airways
• Frontier Airlines
• Hawaiian Airlines
• InterCaribbean Airways
• Japan Airlines
• JetBlue Airways
• Key Lime Air
• KLM Royal Dutch Airlines
• Miami Air International
• Norwegian Air
• PAL Express
• Philippine Airlines
• Porter Airlines
• Qatar Airways
• Scandinavian Airlines
• Seaborne Airlines
• Silver Airways
• Singapore Airlines
• Southern Airways Express
• Southwest Airlines
• Spirit Airlines
• Sun Country Airlines
• Sunwing Airlines
• Swiss International Air Lines
• TAP Air Portugal
• Turkish Airlines
• United Airlines
• Virgin Atlantic
• VivaAerobus
• World Atlantic
• Xtra Airways

If you obtained your KTN through the Global Entry program or by virtue of your status as a US Armed Forces member, you should use it whenever you make an airline reservation, regardless of which airline you fly.

Why Don't I Get PreCheck Status Every Time?

There are several reasons why you might not be able to use the PreCheck screening lane, even though you have a KTN. For example:

Sometimes the TSA does not give PreCheck status to enrolled travelers as part of its effort to randomize security screening procedures.

The data you entered when you bought your ticket might not match the data on file with the TSA, DHS, or DoD. Your first name, middle name, last name, and date of birth must match exactly.

You may have entered your KTN incorrectly when you bought your ticket.

Your KTN might not be saved in your frequent flyer profile, or you may not have logged in to your frequent flyer account before you bought your ticket online.

If you bought your ticket through a travel agent or third party website, such as Expedia, your KTN might not have been passed along to your airline. The best way to correct this problem is to call your airline and make sure your KTN has been entered into your reservation record. Do this before you check-in for your flight.

You may not have noticed that you could not enter your KTN when you purchased your ticket online. This occasionally happens with online travel websites (third party websites). 

How to Resolve Problems

Once you have a KTN, you are supposed to use it. Always look for the KTN field when you buy an airline ticket online. Contact your airline after you complete your purchase if you do not see it.

Double-check your travel documents (driver's license, government-issued photo ID and/or passport ) to be sure your full name and birth date match the information you provided to the TSA or DHS. Save your KTN in your frequent flyer account record(s). Check your frequent flyer account profiles regularly to make sure your KTN is still entered correctly. Train yourself to look for the KTN field and enter your KTN whenever you buy an airline ticket. Call your airline before your check-in date to be sure your KTN has been added to your reservation record.

When you print your airline ticket, you should see the letters "TSA PRE" in the top left corner. These letters indicate that you have been selected for PreCheck status on your flight. If you are enrolled in PreCheck but do not see "TSA PRE" on your ticket, call your airline. The reservations agent will be able to help you sort out any problems. Remember that the TSA will not always select you for PreCheck status, even if you are enrolled in the PreCheck program.

If you encounter problems at check-in or at the airport, contact the TSA as soon as possible to find out what happened. According to the Wall Street Journal , the TSA only retains PreCheck data for three days after your flight, so you will need to act quickly.

TSA PreCheck - What You Need to Know and How to Apply (2024)

I f you haven’t heard, TSA PreCheck for kids has gotten easier! We’ve been using it now for several years and see the benefit. I’ve certainly noticed the uptick in passengers using the expedited security lines at the airport. We feel it’s been worth the investment for the amount of time we spend at airports.

But what is TSA PreCheck, and how do you get it? And how does it work with minors, especially with the new policy? I’ll answer all your questions on TSA PreCheck for minors in this post. If you haven’t jumped on the bandwagon yet, here’s what you need to know about TSA PreCheck.

*Disclosure: This post may contain affiliate links, which means we may receive a commission if you click a link and purchase something that we have recommended. Please check out our disclosure policy for more details. Thank you for your support!

What is TSA PreCheck?

TSA stands for the Transportation Security Administration. TSA PreCheck is a Trusted Traveler program that allows pre-screened individuals to use special security lanes at US airports, called the TSA PreCheck lanes. It’s a must for frequent travelers.

With your 5-year membership, you’ll enjoy the benefit of avoiding regular security lines and getting to your gate faster! That means you don’t have to remove items such as belts, shoes, and light jackets. You can also leave laptops and travel-sized liquids inside carry-on bags.

Where can I enroll for TSA Precheck?

TSA PreCheck isn’t available at every airport, but it is available at 250 U.S. airports and counting. Click here to find a location near you.

How does the TSA application process work?

The process has a couple of steps. To start, you apply on the TSA website using this form . The whole online application process is fairly self-explanatory. Once it’s complete, you’ll be able to schedule an in-person appointment.

Within 45 days of completing your online pre-enrollment form, you’re required to visit an application center (locations can be found here ).

You will need to provide your biographic information including your name, date of birth, and address. You’ll also be fingerprinted and have your photo taken.

What are the necessary documents for TSA PreCheck?

Wondering what to bring to a TSA PreCheck appointment? You can find out about all the required documents needed for TSA PreCheck here . But it’s pretty straightforward:

• Valid ID : Make sure to bring a government-issued ID, such as a passport, or a driver’s license and birth certificate. Double-check the IDs are not expired.
• Appointment Confirmation : Bring the appointment confirmation with you.
• Payment : You’ll need to pay for your TSA PreCheck application during the appointment. This is good for 5 years.
• Proof of Citizenship/Immigration Status : If you’re not a US citizen, you’ll need to bring the necessary documentation to prove your immigration status or a permanent resident.

The non-refundable application processing fee of $78 can be paid through these acceptable forms of payment:

• credit card
• money order
• certified/cashier’s check

Cash and personal checks aren’t accepted.

What is a KTN?

After completing the application process, successful PreCheck applicants will receive a Known Traveler Number (KTN) via US mail in approximately 2-3 weeks.

You may also check the status of your application on the TSA PreCheck website by clicking on “Check My Service Status.”

Once issued, your Known Traveler Number (KTN) is valid for 5 years. You won’t receive a card to carry, but simply a letter with your KTN. Moving forward, you’ll need to provide this number when booking travel reservations.

How to Get TSA Precheck and Global Entry for Free

Several travel credit cards will reimburse your TSA PreCheck fees (and even Global Entry fees). For example, Chase Sapphire Reserve, Delta SkyMiles Platinum American Express Card, and Capital One Venture Card all offer reimbursement via a statement credit for TSA fees.

Now that you have your Known Traveler Number (KTN), what happens next?

When you travel, you’ll want to make sure the airline you’re flying has your KTN in advance. It must be printed on your travel documents. If you belong to a frequent flier program, go on the airline’s website and enter your KTN in their system.

Note that this doesn’t automatically populate every time you book a reservation. So, you’ll want to make sure that it is documented going forward each and every time.

What about TSA Precheck for minors?

So, let’s get to why you’re really here: TSA precheck for kids. It’s pretty straightforward but with a few caveats.

Do children need a TSA PreCheck membership?

Previously, if the whole family wanted to go through TSA PreCheck, those 13 years old and older needed to have their own membership. Thankfully, TSA PreCheck with teens has just gotten easier.

As of May 2023, the TSA PreCheck age has increased to include children of all ages (up to 18 years). That is, as long as they’re accompanied by an eligible parent or guardian. That means your five-year membership applies to all of your kids too!

Just like before, children between 2- and 12-years-old just have to be accompanied by a legal guardian enrolled in the program, no matter what. Kids between 13 and 17 years old just need to be on the same reservation as the accompanying adult.

For teens, just double-check to confirm that the TSA PreCheck indicator shows up on both your boarding pass and your teen’s boarding pass.

This new policy has really streamlined the process since most children don’t have a government photo unless it’s on a passport or a state-issued ID. Our children have passports, so we never had an issue.

Can my child use my TSA PreCheck for international travel?

You can use TSA PreCheck from any participating airlines at over 250 airports across the country, and this includes for international travel.

However, if you’re a frequent traveler abroad, you might want to also consider getting G lobal Entry . You’re eligible if you fly internationally at least 4 times a year. It gives you the benefit of expedited customs when coming back to the US.

As frequent international travelers, we invested in getting each of our kids their own membership, which has a similar policy to TSA Pre-Check.

TSA PreCheck is just one of four Trusted Traveler programs offered by the Department of Homeland Security. To find more information about the other programs such as Global Entry, you can read this comparison chart .

But what about an unaccompanied minor?

All minors traveling without TSA PreCheck-enrolled parents or guardians will need to apply for themselves.

Can I use my TSA PreCheck membership to take my child to their departure gate?

Let’s say your minor is a first-time traveler and you want to take them all the way to their departure gate. First, you’ll need to pick up a gate pass at the ticket counter when you arrive at the airport. But something to keep in mind is that gate passes cancel out TSA PreCheck benefits.

So, even if you’re a gate pass holder with your own TSA PreCheck membership, you’ll have to go through standard security lines. Your child will be able to go through TSA PreCheck screening, but you’ll still have to go through standard security screening.

Have you thought about TSA PreCheck for kids? Do you think it’s worth it?

So, now you know all the details about the updated policy on TSA PreCheck for kids and how to get your own membership. You’ll love the TSA PreCheck benefits! A faster precheck line means less of a headache on your way to your family vacation.

Especially during a busy summer season, the last thing you and your kids want to worry about is congested airport security checkpoints! As TSA PreCheck passengers, you can skip the frustration of standard screening and get right to enjoying your travels!
