How to Check Your TSA PreCheck Expiration Date

Find Your Expiration Date in Your Known Traveler Number

Your TSA PreCheck expiration date is printed on the back of your Known Traveler Number (KTN) card in the bottom right corner. The card itself is a physical credential you received by mail after your background check cleared. If you have the card in front of you, look for a date formatted as MM/DD/YYYY — that is your expiration date.

If you cannot locate your physical card, you can also find this date through the TSA's official website. Go to tsa.gov and select "Check process Status" under the Known Traveler Number section. You will need to enter your process number or your last name and date of birth to retrieve your account information, which displays your current expiration date and status.

PreCheck membership lasts five years from the date your background check was approved, not from the date you applied. Many people confuse the approval date with the expiration date, so verify you are reading the correct field in your account.

Key Takeaways

Your expiration date appears on the back of your physical KTN card in the bottom right corner in MM/DD/YYYY format.
You can also check your expiration date by logging into your TSA account at tsa.gov using your process number or personal details.
PreCheck membership is valid for five years from your approval date, and you should renew before the expiration date to avoid losing benefits at airport security.
If your card is lost or damaged, you can request a replacement through your TSA account without paying the renewal fee again.

Check Your Status Through the TSA Website

The TSA website is the most reliable way to confirm your expiration date if you do not have your card nearby. Visit tsa.gov and look for the "Check process Status" link. You will be asked to provide either your process receipt number (which was emailed to you when you first submitted your process) or your personal information including your last name and date of birth.

Once you log in, your dashboard will show your current status, your Known Traveler Number, and the exact expiration date of your membership. This same page also tells you whether your membership is active, expired, or pending. If you see "expired" on this page, you will no longer receive PreCheck benefits at security checkpoints until you renew.

What Happens When Your PreCheck Expires

When your PreCheck membership expires, you lose access to expedited security screening at participating airports. You will go through standard security lines instead of PreCheck lanes, which means removing shoes, belts, and light jackets, and removing laptops and liquids from your carry-on bag. Your Known Traveler Number will no longer be recognized by the TSA.

Your expired card itself is no longer valid for travel. If you attempt to use an expired KTN when booking a flight, the airline may not recognize it, and you could miss out on PreCheck benefits even if you are otherwise still within your membership window. The safest approach is to renew before your expiration date rather than waiting until after it passes.

Renew Before Your Membership Expires

You can begin the renewal process up to six months before your expiration date. The renewal process is shorter than the initial process and costs $78 to $85 depending on your state. You can renew online through tsa.gov by selecting the renewal option and paying the fee. Some renewal applications are approved within days, though others may take several weeks.

If you renew before your current membership expires, your new five-year term begins on the date your renewal is approved, not on the expiration date of your old membership. This means there is no gap in your coverage if you time your renewal correctly. However, if you wait until after your membership has already expired, you will lose PreCheck benefits until your renewal is approved.

Replace a Lost or Damaged Card

If your physical KTN card is lost, stolen, or damaged, you can request a replacement through your TSA account without paying another fee. Log into tsa.gov, find your process, and select the option to request a replacement card. The TSA will mail a new card to your address on file, usually within two to three weeks.

While you wait for your replacement card to arrive, you can still use your PreCheck benefits at airport security. You will need to provide your Known Traveler Number verbally to the TSA agent or provide it when you book your flight. The number itself does not expire — only the physical card and your membership status matter. If your membership has expired, a replacement card will not restore your benefits; you must renew your membership first.

Mark Your Calendar and Plan Ahead

Write your expiration date on your calendar or set a phone reminder for three months before it expires. This gives you enough time to complete the renewal process without rushing. Many people forget about their PreCheck expiration until they arrive at the airport and discover they no longer have access to expedited screening.

If you travel frequently, renewing early is worth the small effort. The renewal process is faster than the initial process because you do not need to schedule an in-person appointment at an enrollment center — you can complete it entirely online. Keeping your membership current means you will always have access to PreCheck lanes when you need them.

Frequently Asked Questions

Can I use my PreCheck if my card is expired but my membership is still active?

No. The physical card expiration date and your membership expiration date are the same. Once that date passes, your membership is no longer active, and you cannot use PreCheck benefits. You must renew your membership before you can use PreCheck again at security checkpoints.

What if I cannot find my process number to check my status online?

You can still check your status using your last name and date of birth instead of your process number. Go to tsa.gov, select "Check process Status," and choose the option to look up by personal information rather than process number. You will be asked to verify your identity with additional details.

Does my PreCheck expire on the date shown, or do I have until the end of that day?

Your PreCheck expires on the date shown. If your card says 03/15/2025, your membership ends on March 15, 2025, and you should not rely on PreCheck benefits on that date or after. Renew before that date to may support continuous coverage.

If I renew early, do I lose the time remaining on my current membership?

Yes. When you renew, your new five-year term begins on the approval date of your renewal, not on the expiration date of your old membership. If you renew six months early, those six months are not added to your new term. However, renewing early is still worth doing to avoid a gap in coverage.

Can I check my PreCheck status on the TSA mobile app?

The TSA does not have an official mobile app for checking PreCheck status. You must use the website at tsa.gov. However, you can save your Known Traveler Number in most airline apps and mobile boarding passes, which will show whether your PreCheck is active when you book or check in for a flight.
