What TSA PreCheck approval actually requires

TSA PreCheck approval is not a single decision made at one moment. Instead, you move through a process: you submit an online form and pay a fee, then you go to an enrollment center for fingerprinting and a brief interview, and then TSA either approves you or denies you. Approval means you get a Known Traveler Number (KTN) that you enter when you book flights, which lets you use expedited security lanes at U.S. airports for five years.

The process takes about two to three weeks from the time you finish your in-person appointment until you receive your approval notice, though some people hear back faster. You are not approved until TSA sends you a letter or email saying so—not when you pay, not when you finish your interview, but after the agency completes its background check.

Key Takeaways

  • You must be a U.S. citizen or national, a lawful permanent resident, or a citizen of a country with a trusted traveler agreement with the United States.
  • The process costs $78 to $85 depending on your state, and you pay this fee when you submit your online form before your in-person appointment.
  • You must attend an in-person appointment at a TSA enrollment center, where you will be fingerprinted and asked questions about your background.
  • TSA runs a background check that includes criminal history, immigration status, and security-related records; disqualifying factors include felonies, certain misdemeanors, and immigration violations.
  • Your approval is valid for five years, after which you must renew by submitting a new process and paying the fee again.

Who can be approved for TSA PreCheck

You must be a U.S. citizen or national, a lawful permanent resident (green card holder), or a citizen of a country with a trusted traveler agreement with the United States. TSA maintains a list of countries with these agreements on its website; they include Canada, Mexico, the United Kingdom, and several others, but not all countries may have access to.

If you hold a valid passport from one of these countries and have a U.S. visa or travel authorization, you may be able to enroll. Bring your passport and visa documentation to your enrollment appointment if you are not a U.S. citizen or permanent resident.

The online process and fee

You start by going to the official TSA PreCheck website (tsa.gov/precheck) and creating an account. You will fill out a form with your personal information, including your name, date of birth, citizenship status, and contact details. The form also asks about your criminal history, immigration violations, and certain security-related matters—answer these honestly, because TSA cross-checks your answers against its records.

When you submit the form, you pay the fee using a credit or debit card. The fee is $78 to $85 depending on your state; some states charge the lower amount and some the higher. You receive a confirmation number and instructions for scheduling your in-person appointment at a TSA enrollment center near you.

Do not book a flight or make travel plans until after your appointment is complete. You cannot use your KTN until TSA approves you, which happens after your background check is finished.

The in-person appointment at an enrollment center

You must visit a TSA enrollment center in person. These are located at major airports, some post offices, and other government facilities. You can find the nearest center and book your appointment through the TSA PreCheck website. Appointments are usually available within a few days to a few weeks, depending on your location.

Bring your valid passport or state ID, proof of citizenship or permanent residency (such as a birth certificate, naturalization certificate, or green card), and your Social Security card or tax return. Bring the confirmation number from your online process. The appointment itself takes about 10 to 15 minutes. A TSA officer will ask you questions about your background, take your fingerprints digitally, and take a photo for your records.

Be prepared to answer questions about any criminal history you disclosed, any time you have spent outside the United States, and your employment. The officer is not making the approval decision—that happens later when TSA completes its background check. The officer is verifying that the information you provided is accurate and collecting your biometric data.

What TSA checks during the background investigation

After your appointment, TSA sends your fingerprints to the FBI and runs checks against multiple databases. The agency looks at criminal history, immigration records, security watch lists, and other government records. This process typically takes two to three weeks.

Certain offenses automatically disqualify you. These include felonies of any kind, misdemeanors involving violence or dishonesty (such as assault, theft, or fraud), immigration violations, and drug-related offenses. TSA also denies approval for people with outstanding warrants or active security concerns. If you have been denied before, you can reapply after one year, but TSA will review the same records again.

If your background check raises questions but does not automatically disqualify you, TSA may contact you for more information. Respond promptly and honestly to any follow-up requests.

After approval: your Known Traveler Number and renewal

When TSA approves you, you receive a letter or email with your Known Traveler Number (KTN). This is a 10-digit number that you enter in the "Known Traveler Number" field when you book flights online or at the ticket counter. You can also add it to your frequent flyer profile with airlines so it is automatically included in your reservations.

Your approval lasts for five years from the date TSA approves you. About six months before your five-year period ends, you will receive a notice that you can renew. Renewal requires you to submit a new process, pay the fee again, and attend another in-person appointment for fingerprinting. The process is the same as your initial process.

If you move to a different state or country, you do not need to reapply—your KTN remains valid. If you lose your approval notice or forget your KTN, you can look it up on the TSA PreCheck website using your confirmation number from your original process.

What happens if you are denied

If TSA denies your process, you receive a letter explaining the reason. Common reasons include a criminal conviction, an immigration violation, or information that contradicts what you stated on your form. The letter will tell you whether you can appeal the decision or whether you must wait before reapplying.

If you believe TSA made an error, you can request reconsideration within 30 days of receiving the denial letter. You will need to provide documentation that corrects the record—for example, if TSA found a criminal conviction that was actually expunged, you would provide court documents showing the expungement. If TSA denies your reconsideration request, you can reapply one year after the original denial date.

Frequently Asked Questions

Can I use my KTN before I receive my approval letter?

No. You can only use your KTN after TSA has officially approved you and issued it to you. Using a KTN before approval is not possible because the number does not exist in the system yet. Wait for your approval notice before booking flights or entering the number into your airline profile.

What if I have a criminal record from years ago?

It depends on the offense. Felonies disqualify you regardless of how long ago they occurred. Some misdemeanors also disqualify you, while others may not. Contact TSA directly through its website or call the TSA PreCheck customer service line to ask about your specific situation before you pay the process fee.

Do I need TSA PreCheck if I only fly once a year?

That is a personal choice. PreCheck costs $78 to $85 for five years and saves you time at security by letting you keep your shoes and belt on and leave your laptop in your bag. If you fly several times a year, it usually pays for itself in convenience. If you fly rarely, the benefit may not be worth the cost to you.

Can I explore for TSA PreCheck if I am not a U.S. citizen?

Yes, if you are a lawful permanent resident or a citizen of a country with a trusted traveler agreement with the United States. Bring your green card or passport and visa documentation to your enrollment appointment. Check the TSA website to confirm your country has an agreement before you explore.

What should I do if I move before my appointment?

You can reschedule your appointment at a different enrollment center through the TSA PreCheck website. Your process and fee remain valid. straightforward log into your account, cancel your original appointment, and book a new one at a center near your new location.
