How to Check If You Have TSA PreCheck

How to verify your TSA PreCheck status right now

The fastest way to check whether you have TSA PreCheck is to visit the official TSA website at tsa.gov and use their Known Traveler Number (KTN) lookup tool. You will need your full name, date of birth, and the last four digits of your Social Security number. The system will tell you when ready whether an active PreCheck membership is on file under your name.

If you cannot find your KTN online, call the TSA at 1-855-347-8371. A representative can confirm your status and provide your number if it exists. This is also the best route if you are unsure whether you enrolled years ago and forgot about it — the TSA keeps records even if you have not used PreCheck in a while.

Another way to check is to look at your driver's license or state ID. If you enrolled in PreCheck, your state may have printed a TSA PreCheck indicator on the card itself, though not all states do this. Check the front and back for any PreCheck marking or logo.

Key Takeaways

The TSA website lookup tool at tsa.gov is the most direct way to confirm your PreCheck status using your name, birth date, and last four Social Security digits.
Your TSA PreCheck membership lasts five years from the date you enrolled, so checking your enrollment date tells you whether it is still active.
If you enrolled through a trusted traveler program like Global Entry or NEXUS, your PreCheck benefits are included and you can verify status through those programs too.
Your airline confirmation email from enrollment contains your KTN, so searching old email for "TSA PreCheck" or "Known Traveler Number" can surface proof of membership.

What your Known Traveler Number tells you

Your Known Traveler Number is a nine-character code assigned when you enroll in PreCheck. If you have one on file with the TSA, you have an active membership. This number stays the same for the entire five-year term of your PreCheck membership, so if you enrolled in 2020, your KTN is still valid through 2025.

You can find your KTN in several places. Check your PreCheck approval email from when you enrolled — it will list the number clearly. If you booked a flight and added your KTN to your reservation, it appears on your airline confirmation. Some people write it down on their insurance card or keep it in their phone notes.

If you cannot locate the number but the TSA website confirms you have an active membership, write down the KTN the system provides. You will need it to add PreCheck to future flight bookings so the TSA knows to screen you in the expedited line.

Checking your enrollment date and membership expiration

PreCheck memberships expire five years after you enroll. The TSA lookup tool will show you both your enrollment date and your expiration date. If your expiration date has already passed, your membership is no longer active, even if you enrolled years ago.

For example, if you enrolled on March 15, 2019, your membership expired on March 15, 2024. You would no longer be able to use PreCheck at airport security. The TSA website will clearly state whether your membership is "active" or "expired."

If your membership is within six months of expiring, the TSA typically sends a renewal notice to the email address on file. Check your spam folder if you do not see it in your inbox. You can also renew early — the TSA allows you to renew up to six months before your membership expires, and the new five-year term begins on your expiration date, not on the day you renew.

Using your airline account to find your PreCheck status

Most airlines store your KTN in your frequent flyer or online booking profile. Log into your account with any airline where you have flown, go to your profile or account settings, and look for a section labeled "Known Traveler Number," "TSA PreCheck," or "Trusted Traveler Information." If your KTN is listed there, you have an active membership.

If the field is empty or missing, you either have not enrolled in PreCheck or your membership has expired. Adding your KTN to your airline profile is optional — the TSA will still screen you in the PreCheck line if your membership is active, but the airline uses the number to print a special indicator on your boarding pass, which makes the process smoother.

Some airlines also display your PreCheck status when you check in online or at the airport kiosk. If you see a "TSA PreCheck" or "TSA Pre✓" indicator on your boarding pass, your membership is active and recognized by that airline.

Checking if you enrolled through Global Entry or NEXUS

If you enrolled in Global Entry or NEXUS, you automatically received TSA PreCheck as part of that membership. Both programs include PreCheck benefits at no extra cost. To check your status, you can verify your Global Entry or NEXUS membership instead of looking up PreCheck separately.

Visit the Trusted Traveler Program website at trusted traveler.cbp.dhs.gov and log in with your account. Your membership status will show whether your Global Entry or NEXUS is active. If it is, your PreCheck is active too. Your KTN for PreCheck is the same as your Global Entry or NEXUS membership number.

If you enrolled in Global Entry through your credit card issuer (many premium travel cards offer a credit toward the enrollment fee), check your card issuer's website or app. They often display your Global Entry status and KTN in your account dashboard.

What to do if you cannot find proof of enrollment

If you think you enrolled in PreCheck but cannot find your KTN or confirmation email, the TSA lookup tool is your best option. Even if you lost the original email or forgot the details, the TSA database will have your record if you completed enrollment and paid the fee.

If the lookup tool shows no active membership, you have two possibilities: either you never completed the enrollment process (many people start but do not finish), or your membership expired. The TSA representative on the phone can tell you which one applies and whether you need to enroll or renew.

Keep in mind that enrollment requires an in-person appointment at a TSA enrollment center or an approved partner location. straightforward paying online does not set up PreCheck — you must complete the appointment, provide identification, and have your fingerprints taken. If you paid but never showed up for the appointment, your membership was never activated.

Reading your boarding pass for PreCheck confirmation

Once you have confirmed your PreCheck membership and added your KTN to your airline reservation, your boarding pass will display a TSA Pre✓ indicator. This small logo or text appears on paper and mobile boarding passes and tells TSA officers at security that you are enrolled.

The indicator does not always print on your first flight after enrollment — it depends on whether you added your KTN to your reservation before you checked in. If you book a flight without your KTN and add it later, the boarding pass may not update. When you check in for your next flight and include your KTN, the indicator should appear.

If your boarding pass does not show the PreCheck indicator even though you added your KTN, you can still go through the PreCheck line at security. Show your ID and boarding pass to the TSA officer, and they can manually verify your status in their system. However, having the indicator on your pass makes the process faster and clearer.

Frequently Asked Questions

What if the TSA website says I have no record of PreCheck?

If the lookup tool finds no active membership, you either never enrolled or your membership expired. Call the TSA at 1-855-347-8371 to confirm. If you enrolled more than five years ago, your membership has expired and you will need to renew. If you never completed an in-person appointment, you will need to start the enrollment process over.

Can I use PreCheck if my membership expired last month?

No. Once your membership expires, you lose PreCheck benefits when ready. You cannot use the expedited screening line or add your KTN to flight reservations. You must renew your membership through the TSA website or a trusted traveler program to regain PreCheck status.

Do I need to carry my PreCheck card or receipt?

You do not need to carry a physical PreCheck card or receipt. The TSA checks your status using your ID and the information in their database. Your boarding pass will show the PreCheck indicator if your KTN is linked to your reservation. Having your KTN written down or saved in your phone is helpful but not required.

If I have Global Entry, do I still need to check my PreCheck status separately?

No. Your Global Entry membership includes PreCheck, and they share the same membership number. Checking your Global Entry status on the Trusted Traveler Program website confirms your PreCheck is active too. You do not need to enroll in PreCheck separately.

What happens if I show up at security without my KTN on my boarding pass?

You can still go through the regular security line. The TSA officer can look up your status manually if you provide your ID, but you will not get the expedited screening benefit. To use PreCheck consistently, add your KTN to your airline profile and include it when you book flights so the indicator prints on your boarding pass.
