How to Add TSA PreCheck (Known Traveler) Number

Travelers approved in a pre-screening program (TSA PreCheck, Global Entry, Nexus or Sentry) are assigned a Known Traveler Number (KTN), also known as a PASSID, Trusted Traveler, or Secure Flight number. This number must be provided when booking reservations on participating airlines and will be printed on the boarding pass.

If you would like to add your KTN to your Connexxus travel agency profiles for future convenience when making reservations, follow these steps:

BCD Travel – This field is not available to travelers. Central Accounts Payable can update your profile on your behalf. Send an email to with the following information:

    • First, middle, and last name exactly as it matches the pre-screening program’s records
    • Date of birth
    • Gender
    • Known Traveler Number

UC Travel Center – Log into Connexxus, select Book Online, and select UC Travel Center. On the agency’s website, select Profile, then Personal Information, and scroll to Secure Flight Requirements. Be sure to click ‘Save’ at the bottom.

Southwest Airlines – Add the KTN to your Southwest Rapid Rewards profile. Southwest does not accept KTN from any travel agency’s system.

For existing reservations, contact the airline directly. If the airline cannot assist you, contact the travel agency you used to make the reservation.
