All about KTN

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 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 of 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.

 

 

How do I add my Known Traveler Number (KTN) to previous reservations?

Contact your airline by phone or online to add your  Known Traveler Number (KTN). Remember to enter your full name, date of birth, and KTN exactly as you provided during enrollment because 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.  

How do I use my Known Traveler Number or KTN?

Once you have been assigned a Known Traveler Number (KTN), you must include this number in the ‘KTN' field of each reservation you make with a participating airline. The KTN also can be added when booking reservations online via a participating airline website, by phone with an airline reservation agent, or with the travel management company making reservations. Save your KTN to any frequent flyer profiles, employer booking systems, or online travel websites that you use.

I forgot my Known Traveler Number (KTN). How do I find it?

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