If you are a member of the TSA PreCheck® Application Program, look up your KTN online.
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.
If you still are having trouble locating your TSA PreCheck® KTN please submit an online form or call us (866) 289-9673. Representatives are available 8 a.m. to 11 p.m. ET weekdays; 9 a.m. to 8 p.m. weekends/holidays.
