Traveler's Guide: Known Number For Us Passport

If you want to find your Known Traveler Number (KTN) for your US passport, you can do so through the TSA website. The KTN is a 9-digit number that includes both letters and numbers and typically begins with the letters TT. It is issued to individuals approved for TSA PreCheck and must be added when booking airline travel reservations to access expedited screening. If you are a member of another trusted traveler program, such as Global Entry, NEXUS, or SENTRI, you can log in to the Trusted Traveler Program website to obtain your PASSID, which is your KTN.

TSA PreCheck® Application Program

The TSA PreCheck® Application Program allows eligible travelers to receive expedited screening at over 200 participating U.S. airports and on more than 80 airlines. The program offers a more convenient and efficient security screening process, with no need to remove shoes, laptops, liquids, belts, or light jackets.

To enroll in the TSA PreCheck® Application Program, you can either pre-enroll online and schedule an appointment or walk into any of the over 400 enrollment centers across the country. The application process requires an in-person visit to an enrollment center to provide documentation, fingerprints, and photos. The cost of enrollment varies by provider, and there is also a non-refundable $85 fee for background checks.

Once approved for the program, applicants typically receive their Known Traveler Number (KTN) within 3-5 days, although some applications can take up to 60 days. The KTN is a 9 or 10-digit number that begins with TT, TE, or AC, depending on the enrollment provider. This number must be added to each participating airline profile or provided when making flight reservations. It is important to ensure that the name used when applying for TSA PreCheck® matches the name used when booking travel.

The TSA PreCheck® membership lasts for five years, and renewal can be done online or in person. The cost of renewal varies by provider, and it is recommended to renew at least 60 days before the expiration date to avoid a lapse in benefits.

Global Entry

If you are a member of Global Entry, your Known Traveler Number (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. You can find your PASS ID number in two ways:

• Log on to the Trusted Traveler Programs website. Your PASS ID number will be listed towards the bottom of the page.
• Check the back of your Global Entry card. The PASS ID number can be found in the upper-left corner.

Once you have your KTN, you must include this number in the 'KTN' field when booking your travel reservations with a participating airline. The KTN can also be added to your frequent flyer profile. Remember to enter your full name, date of birth, and KTN exactly as you provided them during enrolment. If there is a mismatch in the data entry in the travel reservation, you will not receive the TSA PreCheck indicator on your boarding pass.

If you are unsure whether your airline participates in the TSA PreCheck program, you can check online.

When using a NEXUS lane, hold your membership card in front of the proximity card reader and proceed to the inspection booth for a visual inspection. If you are using a lane with a NEXUS eGate, you will be processed by an officer inside the CBSA office via a video camera and intercom.

If you are a member of NEXUS, your Known Traveler Number (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.
