Your Global Entry number is the same as your Known Traveler Number (KTN). Here are the most common places to find it:
The 9-digit number on the front of your physical card is your KTN/Global Entry number. It usually begins with 15, 98, or 99.
Search your email for messages from “Trusted Traveler Programs” or “U.S. Customs and Border Protection (CBP)”. Your approval or conditional approval notice should include your KTN.
If you’ve used Global Entry for a flight, your KTN is often printed on your boarding pass. Look for a line that says “KNOWN TRAVELER” or “PASS ID”.
