The Global Entry number is on the back of your Global Entry card, usually the nine-digit PASSID/KTN number near the top-left area or just above the barcode, depending on the card design.

Quick check

  • Look on the back side of the card.
  • It should be a nine-digit number labeled PASSID, which you can use as your Known Traveler Number for airline bookings.
  • If you do not have the card handy, you can also find it in your Trusted Traveler Program account.

Small note

Some people see two numbers on the back of the card; the one you usually want for travel is the PASSID/KTN, not the other number.
