TSA Pre✓®

TSA Pre✓® is an expedited security screening program connecting travelers departing from the United States with smarter security and a better air travel experience.

If you’re eligible and approved for the TSA Pre✓® program you will be given a known traveler number “KTN” to use when making flight reservations. Participating airlines will print an indicator on your boarding pass. When you arrive at the airport, look for signs for the lanes.

How do I use my Known Traveler Number?

Once approved as eligible for TSA Pre✓®, you must enter the provided number in the ‘known traveler number’ field when booking travel reservations on any of the participating airlines.  The KTN also can be added when booking reservations online via a participating airline website, via phone call to the airline reservation agent, or with the travel management company making reservations.  Additionally, the KTN can be entered in participating airline frequent flyer profiles, where it will be stored for future reservations. You can also store the KTN in your frequent flyer profile for future reservations.

Please make sure the name used when applying for the TSA Pre✓® application program matches the name used when booking travel.

TSA Pre✓® eligibility will be identified with an indicator on the boarding pass.

Will I receive a card or credential to be used when traveling?

No. There is no card or credential provided by the TSA Pre✓® Application Program. You will receive a written notice via U.S. mail within two to three weeks with a known traveler number. The known traveler number can be provided online when booking a flight, saved in the flyer profile, or provided verbally to the airline representative when booking travel by phone.

What if I receive a preliminary determination of ineligibility letter from TSA?

If TSA finds potentially disqualifying information, TSA will send you a letter with instructions on how to proceed.

How do I apply for TSA Pre✓® ?

To receive TSA Pre✓® expedited screening, you can apply for one of four DHS trusted traveler programs (TSA Pre✓® Application Program, Global Entry, NEXUS or SENTRI) if you are not already a member of a DHS trusted traveler program or are not a member of the U.S. Armed Forces.

What is a CBP PASSID and known traveler number?

The PASSID is assigned to you when you enroll in Global Entry, Nexus or Sentry. This nine-digit number usually begins with 98, serves as your KTN and can be found on the back of your card. You can also verify this information by logging into GOES. Choose the “Change Profile” option to verify first/middle/last name/date of birth and PASSID, which is your KTN. Your trusted traveler card will not grant you access to TSA Pre✓®; TSA Pre✓® must be printed on your boarding pass in order to receive expedited screening benefits. Members of the TSA Pre✓® Application Program have a KTN that starts with the letters TT. Please provide this number when booking a reservation on one of the participating airlines. You may obtain a KTN if you are enrolled in one of the four trusted traveler programs.

Can I use TSA Pre✓® when flying from a U.S. airport to a foreign country?

Yes. TSA Pre✓® is available for passengers traveling domestically within the United States and when departing from a U.S. airport to a location outside the country. Passengers may also be eligible for TSA Pre✓® when connecting to a domestic flight after arrival in the United States. TSA Pre✓® is available full-time or during peak times at participating airports.

How will I know that I have been cleared for TSA Pre✓®?

Participating airlines will print a TSA Pre✓® indicator directly on the boarding pass. Travelers cleared for TSA Pre✓® will have information embedded in the barcode of their boarding pass. Once the boarding pass is scanned at the checkpoint, the TSA officer may refer you to the TSA Pre✓® lane. 

If TSA Pre✓® is not available at my airport, why was it printed on my boarding pass?

Travelers are vetted for TSA Pre✓® every time they fly. TSA and airlines do not limit printing of the TSA Pre✓® indicator to the participating airports.

If I present my CBP trusted traveler card (Global Entry, NEXUS or SENTRI), will TSA allow me to utilize the TSA Pre✓® lane?

No. This card is used by CBP at land border crossings and is not accepted by TSA for expedited screening access. The CBP PASSID is a nine-digit number that usually begins with 98 and serves as your known traveler number. Your individual reservation — passenger name record — must include your KTN. Travelers can check with the airlines to verify their KTN is listed in the passenger name record. Travelers who have been cleared for TSA Pre✓® will have information embedded in the barcode of their boarding pass and will have an indicator printed directly on the boarding pass.

I forgot my KTN. How do I find it?

  • Participants in a CBP program should visit the Global Online Enrollment System website to obtain their PASSID, which is their KTN.
  • Participants in the TSA Pre✓® Application Program should visit the Universal Enrollment Services website to obtain their number.

Does my first/middle/last name have to match the information from my trusted traveler program application?

Ensure your airline frequent flyer profile and any previous reservations include your known traveler number. Verify that the airline has your first/middle/last name and correct date of birth and matches the information you supplied when applying for the trusted traveler program. 

How do I add my KTN to my frequent flyer profile on one of the participating carriers?

Ask your carrier(s) to update your profile information and/or saved Secure Flight data. By updating your airline profile, you still have to notify your carrier to make sure your KTN/Secure Flight data is in each reservation correctly, with the same information used when applying for one of the trusted traveler programs. Some air carriers will need proof of your full name to make changes to your frequent flyer profile. Please contact your carrier directly for more information. Updating your frequent flyer profile will not automatically update any previous reservations.

How do I add my KTN to previous reservations?

Contact your air carrier or visit their website to add your KTN to any previous reservations. The airline also can confirm that your first/middle/last name are in the correct Secure Flight fields. The KTN will be submitted along with Secure Flight passenger data to TSA. Remember to enter your full name, date of birth and KTN exactly as you provided during the TSA Pre✓® application process or when you enrolled in a CBP trusted traveler program.

My KTN is saved in my airline profile. Do I have to add it individually to each reservation?

Yes. Your known traveler number saved in your airline profile is not automatically applied to your upcoming reservation. Your individual reservation must include your KTN. Travelers can check with the airlines to verify their KTN is listed in the reservation.

I book my travel via a third-party website and/or travel agency; will I still receive TSA Pre✓®?

Yes. However, sometimes the KTN will not transfer and/or the name may not match. At times, third-party systems merge your middle name with your last name in the Secure Flight data. When in doubt, call the carrier to verify that your information is an exact match. This will increase the probability of receiving TSA Pre✓® on your next flight.

If I have been issued more than one KTN, which one should I use?

A traveler can use any known traveler number that they have been issued. However, please verify that the airline has your first/middle/last name and correct date of birth that is associated with that KTN. Your individual reservation must include your KTN. Travelers can check with the airlines to verify their KTN is listed in the reservation. Incorrect name and/or date of birth information will not clear you for TSA Pre✓® expedited screening.

I’m traveling with my family; can they also use the TSA Pre✓® lane?

  • Family members ages 12 and under traveling with an eligible parent or guardian with a TSA Pre✓® indicator on their boarding pass can participate in expedited screening.
  • Family members 13 and older must go through standard security lanes or should apply for a DHS trusted traveler program.

Can foreign citizens participate in TSA Pre✓®?

Foreign citizens enrolled in Global Entry may participate in TSA Pre✓®. To participate, the CBP PASSID, a nine-digit number that usually begins with 98, serves as your known traveler number. Your individual reservation — passenger name record — must include your KTN when booking on a participating TSA Pre✓® airline.

How should I fill out my name on my application?

The name on the application must exactly match the name on the applicant’s identity and proof of citizenship/immigration documents and be the name used when  booking travel reservations.

What happens after I submit my application?

TSA’s goal is to provide you with a response within 2-3 week of receiving the information you provided at enrollment. This may take longer if there was difficulty capturing your fingerprints during enrollment.

Once cleared, you will receive notification via first-class, untraced mail with your known traveler number, which you then use to fill in the KTN section on airline reservations and profiles. You may also retrieve your KTN here.

Is there an age restriction to apply for TSA Pre✓®?

There is no age restriction to apply for TSA Pre✓®. However, family members ages 12 and under traveling with an eligible parent or guardian with a TSA Pre✓® indicator on their boarding pass can participate in expedited screening.

How do I update my personal information for my TSA Pre✓® membership?

Please contact Universal Enrollment Services at 855-347-8371 between 8 a.m. and 10 p.m. weekdays to make changes to your name, address, or other information contained in your profile. You may submit your inquiry online by visiting and selecting the “Contact Us” tab. A representative will inform you of the documentation needed to process the change.

How was the application fee determined?

TSA Pre✓® for Military

Is there something printed on my boarding pass indicating that I am pre-approved for TSA Pre✓®?

Yes, a TSA Pre✓® indicator will appear on your boarding pass. However, if you entered your DoD ID number when booking travel, proceed to the dedicated TSA Pre✓® lane to check eligibility.

Can I still participate if I make my reservations through a Commercial Travel Office?

Yes. When the CTO asks you to verify your Secure Flight personal information (full name, birthdate, gender), provide your DoD ID number as the known traveler number. CTOs are not required to ask travelers for their known traveler number, but will enter it in the reservation if the traveler volunteers the information.

Do I have to have my DoD ID number in my Defense Travel System profile to participate?

No. DTS will prompt you each time you make an airline reservation to verify your TSA Secure Flight information; you can enter your DoD ID into the known traveler field at that time. Saving your DoD ID number as part of your profile will prevent you from having to enter it each time you make an airline reservation through DTS. It is important to note that updating your profile with your DoD ID number will only qualify you for expedited screening for new reservations and does not apply to existing reservations.

Can I still participate if I have existing reservations?

Updating your DTS profile with your DoD ID number will only apply to new reservations, not existing reservations. Updating existing reservations is not recommended as this may incur additional fees. However, if you have an existing reservation with a commercial TSA Pre✓® participating airline booked outside of DTS, then you may contact the airline to update the reservation with your known traveler number (DoD ID number).

Can I present my CAC to the TSA document checker to participate in TSA Pre✓®?

No. All members of the U.S. Armed Forces must include their DoD ID number when making reservations to receive TSA Pre✓®.

Can Defense Department and Coast Guard civilian employees participate? How do I use the milConnect website to “opt-in?”

Yes. However, DoD and Coast Guard civilian employees first must “opt-in” to TSA Pre✓® by visiting the milConnect website. After selecting the “My Profile” and the “CIV” menu tab when logged into the website, users will be guided through the opt-in process for TSA Pre✓®. Civilian employees need to opt-in only once. Members of the U.S. Armed Forces are already eligible and do not need to opt-in.

I am a member of the U.S. Armed Forces. How I get TSA Pre✓®?

Enter your DoD ID number located on the back of the common access card also known as CAC into the “known traveler number” field when booking flight reservations or when updating your Defense Travel System profile for official travel.

Can I use this program for personal travel?

Yes. To participate, include your DoD ID number in the known traveler number field when making reservations through an airline or travel website. Travelers may also save their DoD ID number in their frequent flyer program profile.

Are other individuals who have a CAC or DoD ID card eligible?

At this time, only members of the U.S. Armed Forces — including those serving in the U.S. Coast Guard, Reserves and National Guard — may use TSA Pre✓®. DoD and U.S. Coast Guard civilian employees are also eligible to participate once they “opt-in” via the milConnect website.

Are members of the U.S. Public Health Service Commissioned Corps or National Oceanic and Atmospheric Administration Commissioned

No. At this time, these employees are not eligible to participate. However, TSA continues to work with various federal government agencies to expand participation to additional vetted employees in the future.

If my family is traveling with me, can they also go through the TSA Pre✓® lane?

Do service members need to be in uniform to participate?

No. Members of the U.S. Armed Forces do not need to be in uniform or on official travel to participate in TSA Pre✓®.
