What is a Known Traveler Number (KTN)?

A Known Traveler Number (KTN) is issued to all individuals approved to receive TSA PreCheck® expedited screening.  The KTN must be added in the KTN field when booking airline travel reservations to have the TSA PreCheck® indicator appear on your boarding pass.    

For members approved for the TSA PreCheck® Application Program, this number is 9 or 10 digits long, can be a combination of numbers and letters and typically begins with TT for those who enrolled through IDEMIA or TE for those who enrolled through Telos both which are official TSA PreCheck® enrollment providers. 

For members approved for Global Entry, NEXUS, or SENTRI, the KTN is the CBP PASS ID number. This nine-digit number usually begins with 10, 13, 14, 15, 16, 50, 70, 80, 95, 98, or 99 and can be found on the back of your NEXUS, SENTRI, or Global Entry card in the upper-left corner or by logging on to the Trusted Traveler Programs website. Your trusted traveler card will not 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.

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.

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).

Since several cards offer this benefit, consider the other benefits of your credit card options before you choose one. Look at the points they earn, trip delay protection, purchase protection, elite status, or airport lounge access.

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. You’ll also receive a $300 travel credit that is automatically applied to your first $300 in travel purchases each cardmember year (this includes taxis, Uber , Lyft , train tickets, flights, hotels, and more).

If airport lounge access and elite status are your top priorities, the Amex Platinum card and Amex Business Platinum card provide world-class lounge access , including Centurion Lounges and Delta Sky Clubs (when flying Delta), on top of a Priority Pass Select membership upon enrollment. 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.

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.”

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.

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.

What is a Known Traveler Number?

How to get a known traveler number, can i add my ktn to an existing reservation, can you add a ktn after checking in, ktn lookup tips, where is a known traveler number on a global entry card, a known traveler number unlocks tsa precheck.

The U.S. Transportation Security Administration launched TSA PreCheck in December 2013. This Trusted Traveler Program, designed to make airport security a smoother experience for its members at select airports across the U.S., is available to travelers who pay an $78 fee and complete a background check, in-person interview and fingerprint scan.

After completing the necessary application steps, approved TSA PreCheck members are given what’s called a Known Traveler Number, or KTN.

TSA PreCheck members aren't given identification cards like members of other Trusted Traveler Programs (e.g., Global Entry , Nexus , SENTRI ).

Instead, the KTN is the primary identifier and effectively serves as your TSA number. Travelers are wise to keep this number handy, as it must be input into every eligible flight booking to take advantage of screening benefits.

Any U.S. citizen, U.S. national and legal permanent resident — without a criminal history — is eligible for preapproval for the TSA PreCheck membership program. Immigrants can learn more about the necessary application materials on the Department of Homeland Security website .

You can apply online quickly. Then, you’ll need to schedule an in-person TSA PreCheck interview appointment at an enrollment center. The interview process is fairly straightforward; most importantly, you will need to bring several documents and proof of identity to your appointment. Examples of approved unexpired U.S. government-issued photo identifications include your passport, driver’s license or birth certificate.

Children 12 and younger don't need their own TSA PreCheck membership. As long as they are traveling with an adult who is a member, they can use the TSA Security lanes, too. Children 13-17 can as well, but only if the TSA PreCheck indicator appears on their boarding passes.

You can find out more about applying for TSA PreCheck to get a Known Traveler Number in our full article on how to get TSA PreCheck .

How long does it take to get a KTN number?

Most applicants will get their KTN within three to five days of membership approval. The TSA PreCheck website also states that it can take up to 90 days to receive a KTN.

Now that you have a Known Traveler Number, it's time to start taking advantage of the benefits. Because airlines are unaware of which passengers have TSA PreCheck screening benefits and which don't, you'll need to add your KTN to each flight booking.

This is most easily done at the time of booking. Your boarding pass should show something like "TSAPRECHK," "TSA PRE," or "TSA Pre✓" to indicate that your KTN was successfully added to your reservation. The specific type of indicator depends on the airline and type of boarding pass (i.e., digital or printed).

However, if you forget, it’s still possible to add your KTN to your ticket ahead of travel. We’ve broken down the steps in this article for passengers flying on Southwest Airlines, American Airlines, Delta Air Lines and United Airlines: How to Add TSA PreCheck to Your Airline Ticket .

If you have a flight coming up shortly and have yet to add your KTN to your ticket, you’re not out of luck. But there are a few extra steps involved before you’re able to enjoy the security benefits.

For those who’ve checked in online without a KTN in the system, you may need to call the airline’s customer service to add your KTN and have a new boarding pass issued.

If call wait times are long, you can also add your KTN to your ticket at the airport. Visit a service desk agent or check-in agent before passing through security. After providing your KTN, these agents should be able to print your boarding pass with the necessary information so you can use the faster security lines.

You might be wondering: How do I find my KTN number? If you’ve forgotten your KTN, the process to retrieve it is simple. Head to the TSA website and click the link to “Look up your KTN online.” You’ll input your full name, date of birth and at least one method of contact (phone or email).

If you’re an automatic member of TSA PreCheck due to your Global Entry enrollment, you won't be able to do a Known Traveler Number lookup through the TSA website. Instead, log into your Global Entry account on the Homeland Security website and locate your PASSID. This applies for Nexus and SENTRI members as well.

You can also use your Universal Enroll ID, or UEID, number and date of birth to conduct a Known Traveler Number lookup. Your UEID is assigned when you apply for TSA PreCheck online and before your interview; see your confirmation email to find this information.

What if I can’t find my KTN number?

You might input your information into the KTN lookup link and receive a denial message that says “No status found.”

In the case that your information is correctly provided and you’re still unable to be located in the system, you can call Homeland Security at 855-347-8371 for assistance.

Your Known Traveler Number, also known as PASSID, can be quickly retrieved by reading the back of your Global Entry card. This number is typically nine digits long and usually begins with 15, 98 or 99.

TSA PreCheck members are identifiable through a Known Traveler Number. This number needs to be added to individual flight bookings to ensure access to expedited airport security screening; it can be added to flight reservations at the time of booking, after booking and even after checking in.

If you’ve lost your KTN, you can use a Known Traveler Number lookup online to retrieve your identification number or find it from the back of your Global Entry card.

THE COST, PROCESS, AND BENEFITS OF ENROLLING IN THE TSA PRECHECK OR GLOBAL ENTRY PROGRAMS

July 21, 2023 | 3 min read.

The last time you booked a flight a flight online, you may have noticed a field for entering a KTN (Known Traveler Number). While this number isn't required, having a KTN offers some benefits. If you're flying more than once a year, having a KTN could make your time in airport security faster and easier.

WHAT IS A KTN? A KTN is a 9-digit, unique number that identifies a traveler who is eligible to receive expedited screening through airport security. Those who pay for and are approved for TSA PreCheck receive a KTN. Those who pay for and are approved for Global Entry, NEXUS, or SENTRI, receive a PASSID, which is essentially the same as a KTN.

If you have a KTN, it's important to add it when booking airline travel to ensure the TSA PreCheck indicator appears on your boarding pass. If the TSA PreCheck indicator is not on your boarding pass, you'll have to go through standard security, even if you've been approved for TSA PreCheck.

BENEFITS OF HAVING A KTN TSA PreCheck offers travelers a faster and more convenient experience in U.S airports. Program participants can access special security lanes that are typically shorter than general security lines.

According to TSA , in March 2023, 89% of TSA PreCheck passengers waited in line for less than five minutes. That means travelers could potentially save hours each year.

When using TSA PreCheck lanes, you're not required to remove your shoes, belts, and light jackets while moving through the screening process. You also don't need to remove laptops or liquids from your bags before they are scanned.

HOW TO GET A KTN Enrolling in TSA PreCheck and receiving a KTN requires paying a $78 application fee and completing an in-person interview at an enrollment center. You'll be digitally fingerprinted during the interview to lessen the time needed for the required background check. Once approved for the program, your membership is good for five years before renewal is required.

Alternatively, international travelers can apply for Global Entry . This trusted traveler program grants expedited entry into the U.S. from international destinations. In addition, program participants automatically receive access to TSA PreCheck during domestic travel. The application fee for Global Entry is $100 and membership is valid for five years.

Check the benefits associated with your credit cards, as many credit card companies will reimburse cardholders for the application fee.

If you ask anyone about their favorite part of their last vacation, they’re unlikely to mention waiting in line at airport security or going through customs. Even seasoned travelers dread removing their shoes and separating their belongings under the pressure of a long line. That’s where Trusted Traveler Programs come in. With these programs, you’re pre-approved to access shorter lines and easier processes. Once you’re accepted, you’ll receive a Known Traveler Number (KTN) that allows you to enter lanes at the airport specifically for members. Here is what you need to know about getting a KTN and how having the right credit cards could help you cover the cost. 

What is a Known Traveler Number?

4 benefits of having a known traveler number, how to get a known traveler number, faqs about known traveler numbers, the final word on known traveler numbers.

A Known Traveler Number is a number that identifies you as a member of a Trusted Traveler Program. You’ll get a KTN when you apply for TSA PreCheck , Global Entry, NEXUS, or SENTRI.

There are key differences between the TSA PreCheck and Global Entry programs . With TSA PreCheck, you’ll get shorter security lines, and you won’t have to remove items from your bag or take off your shoes or belt. Global Entry is intended for international travelers. It provides the TSA PreCheck benefit and also allows speedy clearance through U.S. Customs and Border Protection with automatic kiosks. NEXUS and SENTRI are less popular in the U.S., but both offer similar benefits.

Once you’re approved for a Trusted Traveler Program, you’ll get a KTN, which you’ll need to provide every time you make a reservation with a participating airline. Your TSA PreCheck indicator will then be embedded in the barcode on your boarding pass; you won’t use an ID card to get entry to the TSA PreCheck lanes.

• Wait five minutes or less. Nearly 94% of TSA PreCheck members waited just five minutes or less in their security lanes in January 2020.
• Leave on your shoes, belt, and jacket. With your Known Traveler Number, you’ll be able to fly through security without removing lightweight jackets, belts, or shoes, so you won’t have to step on a dirty airport floor, lose your pants, or catch a chill.
• Leave your bag closed. There’s no need to remove your laptop or liquid items from your bag when you have a Known Traveler Number.
• Enjoy the benefits at major U.S. airports and worldwide. TSA PreCheck is available at more than 200 airports and 73 airlines. If you have Global Entry, you’ll also get access to expedited entry in other countries. NEXUS provides expedited entry into the U.S. from Canada, and SENTRI provides expedited entry into the U.S. from Canada and Mexico.

To get a KTN, you’ll need to apply for TSA PreCheck, Global Entry, NEXUS, or SENTRI. To apply for each program, you need to complete an online application and schedule an in-person appointment. Here’s what’s required for each.

Once you’re approved, you’ll receive a Known Traveler Number for TSA PreCheck or a PASSID for Global Entry, NEXUS, and SENTRI. Both can be used as a KTN when making a reservation.

Can I look up my Known Traveler Number?

Yes. If you’re a member of TSA PreCheck, you can look up your KTN online . You’ll need to provide your name, date of birth, and one method of contact. If you’re a member of Global Entry, NEXUS, or SENTRI, login to the Trusted Traveler Program site to obtain your PASSID, which you’ll use as your Known Traveler Number.

Is a redress number the same as a Known Traveler Number?

No. A redress number is the identifier you get when you apply for redress through the DHS Travel Redress Inquiry Program. This is an option for travelers who have been repeatedly flagged for additional screening and want to have errors corrected in the DHS system. A KTN, on the other hand, gets you access to TSA PreCheck lanes.

Can I add my Known Traveler Number after booking?

Yes. You’ll need to contact your airline by phone or online to add your KTN to your reservation.

How many digits are in a Known Traveler Number?

There are nine digits in a Known Traveler Number. PASSID numbers are also nine digits and can be used as a Known Traveler Number.

Why is my Known Traveler Number not on my boarding pass?

Your Known Traveler Number will not be listed on your boarding pass. Instead, your boarding pass will have a TSA PreCheck indicator. If you don’t see the indicator, it may be because:

• You had a disqualifying criminal offense

It’s not just a nine-digit number; It’s your ticket to shorter lines and less stress, so you can start relaxing before you reach your destination. Membership to Trusted Traveler Programs is good for five years, which makes the brief appointment and fee well worth it for frequent travelers. Many of the best travel credit cards , like the Chase Sapphire Reserve , offer fee credits for Trusted Traveler Programs as well. (You can get reimbursed for TSA PreCheck and Global Entry fees with these 20 cards .) To enjoy less waiting and hassle next time you go to the airport, apply for your KTN today.
