Your TSA PreCheck Expired, But You Have Global Entry: Which Number Do You Use?

By WirelessPhreak Tuesday, October 13, 2026 Labels: Travel

You go to book a flight, and the airline asks for your Known Traveler Number (KTN). You remember enrolling in TSA PreCheck years ago, but that membership has expired. You also have Global Entry. So which number goes in the box?

The short answer

Use your Global Entry number. If your Global Entry membership is active, it works as your KTN and gives you TSA PreCheck eligibility. You don’t need to renew standalone PreCheck.

Why are there two different numbers?

A Known Traveler Number is the ID that tells airlines and TSA you’ve been vetted for expedited screening. Different programs issue their own:

TSA PreCheck (standalone) comes with its own KTN.
Global Entry comes with a separate number, often called a PASS ID. It also works as a KTN for PreCheck, because Global Entry includes PreCheck benefits.

So the numbers differ, but the Global Entry one does everything the PreCheck one did, plus expedited customs when you return to the U.S.

Where to find your Global Entry number

Log in to your Trusted Traveler Programs account at ttp.dhs.gov. Your PASS ID is listed there.
Check your Global Entry card. The number is printed on it.

What to do with the old PreCheck number

Stop using it. Once it expires, it’s no longer valid, and leaving it in your airline profiles can cause your boarding pass to show up without the PreCheck designation.

Take a few minutes to update your KTN in:

Every airline frequent flyer account
Any travel booking sites or apps where you’ve saved traveler details
Saved passenger profiles for trips you’ve already booked (you can usually add it by editing the reservation)

Double-check your Global Entry expiration

Before you rely on it, make sure your Global Entry membership hasn’t expired too. Global Entry lasts five years, and it’s easy to lose track. You can check your status in your TTP account, and you can usually start renewal well before the expiration date.

If your boarding pass doesn’t show PreCheck

Sometimes the KTN is entered correctly but the PreCheck indicator still doesn’t appear. If that happens:

Confirm the name on your reservation matches your Global Entry record exactly.
Make sure the date of birth on your booking is correct.
Re-enter the number with no spaces or dashes.
Contact the airline to add or correct the KTN.

Bottom line

An expired TSA PreCheck membership isn’t a problem if you have an active Global Entry membership. Swap in your Global Entry number as your KTN, update your airline profiles, and keep breezing through the shorter security line.
