Military members can use their military ID to get TSA PreCheck without paying the standard fee

If you are on active duty, in the Reserve or National Guard, or retired from the military, you can get TSA PreCheck through a military-specific pathway that costs nothing. You do not need to pay the usual $78 to $85 fee that civilians pay. Instead, you present your military ID at a TSA PreCheck enrollment center and complete a brief in-person appointment. The process takes about 10 to 15 minutes, and you walk out with a Known Traveler Number (KTN) that you use on every flight.

The military pathway exists because the Department of Defense has already vetted military personnel through background checks far more thorough than TSA's standard screening. TSA recognizes this and lets you skip their fee-based vetting process entirely. You still need to show up in person—there is no mail-in or online-only option—but the appointment itself is straightforward.

Key Takeaways

  • Active duty, Reserve, National Guard, and retired military members can get TSA PreCheck free by showing a valid military ID at an enrollment center.
  • You must visit a TSA PreCheck enrollment center in person; there is no remote or online-only pathway for military applicants.
  • The appointment takes 10 to 15 minutes and you receive your Known Traveler Number when ready or within a few days.
  • Your TSA PreCheck benefit lasts five years from the date you enroll, and you can renew using the same military ID pathway.

What military ID qualifies you

You need a current military ID card issued by the Department of Defense. This includes active duty military, Reserve and National Guard members, retirees, and dependents of active duty or retired service members who have their own ID card. The ID must be valid—expired military IDs do not work, even if you are still serving.

If you are a dependent of a military member and have a military ID in your own name, you can use it. If you do not have a military ID but are a spouse or dependent of someone on active duty, you may be able to get one through your sponsor's base or through DEERS (Defense Enrollment may be able to access Reporting System). Check with your sponsor's personnel office or the base ID card facility first.

Finding and visiting a TSA PreCheck enrollment center

TSA PreCheck enrollment centers are located at major airports, some post offices, and a few other locations. To find the nearest center, go to the official TSA PreCheck website and use their enrollment center locator tool. Enter your zip code or city, and the tool shows you every center within a reasonable distance, along with hours and whether they accept walk-ins or require an appointment.

Most enrollment centers accept appointments, and some accept walk-ins during certain hours. Booking an appointment online through the locator tool is usually faster than calling or showing up without one. When you book, you will see available time slots for the next few weeks. Choose a time that works for you and bring your military ID and one form of government-issued photo ID (such as a driver's license or passport).

What to bring to your appointment

Bring your valid military ID and one additional form of government-issued photo identification. A driver's license, passport, or state ID all work. You do not need to bring proof of citizenship, birth certificate, or any other documents—the military ID is your credential, and your photo ID confirms your identity.

Wear clothing that allows the TSA officer to see your hands and wrists clearly, since they will take your fingerprints during the appointment. You do not need to remove shoes, belts, or jackets for this appointment—it is not a security screening, just an enrollment process. Arrive a few minutes early so you have time to check in.

What happens during the appointment

The officer will verify your military ID, check your photo ID, and ask you a few basic questions about your background. They will take your fingerprints digitally using a scanner. The whole process takes 10 to 15 minutes. You will not be asked to undergo a full background investigation because TSA already trusts the military's vetting process.

At the end of the appointment, the officer will give you a receipt with your Known Traveler Number (KTN) printed on it. Some centers issue the KTN on the spot; others mail it to you within a few days. Either way, you can start using your KTN on flights as soon as you have it. Write down the number or take a photo of the receipt so you have it handy when you book your next flight.

Using your Known Traveler Number on flights

When you book a flight, enter your Known Traveler Number in the "Known Traveler Number" field during checkout. Most airline websites have this field on the same page where you enter your name and date of birth. If you do not see it, look under "Frequent Flyer" or "Special Services" sections. You can also add your KTN to your airline frequent flyer profile so it auto-fills on future bookings.

At the airport, TSA PreCheck lets you go through a shorter security line, keep your shoes and belt on, leave your laptop and liquids in your bag, and keep your light jacket on. You still go through a metal detector or body scanner, but the process is faster. Your KTN works at all U.S. airports and on all airlines.

Renewing your TSA PreCheck after five years

Your TSA PreCheck benefit lasts five years from the date you enroll. About 90 days before it expires, TSA will send you a renewal notice. You can renew by visiting an enrollment center again with your military ID, just as you did the first time. The renewal appointment is the same length and process as the initial appointment, and there is no fee.

If you let your TSA PreCheck expire, you can still renew using the military pathway as long as you have a valid military ID. You do not lose the benefit permanently—you just need to go back to an enrollment center and repeat the process. Some military members set a calendar reminder for the month before expiration so they do not forget.

Frequently Asked Questions

Can I get TSA PreCheck online or by mail if I have a military ID?

No. Even though military members do not pay a fee, you must visit a TSA PreCheck enrollment center in person to complete the appointment. There is no remote or mail-in pathway for any applicant, military or civilian.

What if my military ID is expired but I am still serving?

You cannot use an expired military ID for TSA PreCheck enrollment. You must renew your military ID first through your base or personnel office, then visit the enrollment center with the new card. The renewal process for a military ID usually takes a few days to a week.

Do military dependents without their own ID card may have access to?

Only if you have a military ID in your own name. If you are a spouse or dependent without a military ID, you would need to go through the standard civilian TSA PreCheck process and pay the fee. Ask your sponsor's base ID card facility whether you are may be able to access for a dependent military ID.

Can I use my military ID to get TSA PreCheck at any enrollment center?

Yes. Any TSA PreCheck enrollment center in the country will accept a valid military ID and process you for free. You do not need to go to a center near a military base—civilian enrollment centers at airports and post offices handle military applicants the same way.

What if I separate from the military after I get TSA PreCheck?

Your TSA PreCheck remains valid for the full five years, even after you leave the military. You do not need to renew early or lose the benefit. When it expires and you want to renew, you can use your military retiree ID if you are retired, or you would need to pay the civilian fee if you are no longer may be able to access for a military ID.
