What are a CBP PASSID and known traveler number?

The CBP PASSID is assigned to you upon approval for membership in Global Entry, NEXUS, or SENTRI. This nine-digit number usually begins with 98, serves as your known traveler number, and can be found on the back of your NEXUS, SENTRI, or Global Entry card or by logging on to the Trusted Traveler Program website.

Your trusted traveler card will not grant you access to TSA Pre✓® lanes. The TSA Pre✓® indicator must be printed and embedded in the barcode of your boarding pass in order to receive expedited screening benefits. 

Global Entry, NEXUS, and SENTRI are programs of U.S. Customs and Border Protection. These programs offer travel benefits to pre-screened members. If you join Global Entry, NEXUS, or SENTRI, use your membership number as a “known traveler number” in airline reservations to receive TSA Pre✓®.
