Your TWIC card does not automatically give you TSA PreCheck — you have to link them together in the TSA system

A TWIC card (Transportation Worker Identification Credential) is issued by the Department of Homeland Security for port workers, truck drivers, and other transportation employees. It is not the same as TSA PreCheck, but if you have a valid TWIC, you can use it to get TSA PreCheck benefits at airport security without paying the separate $78 to $85 fee that most travelers pay.

The process is straightforward: you enroll in TSA PreCheck through the official TSA website, list your TWIC card as your credential during enrollment, and then use that TWIC card at airport security lanes marked for PreCheck passengers. You do not need to explore for a separate PreCheck card or visit an enrollment center if your TWIC is current and valid.

The catch is that your TWIC must be active and not expired. If your TWIC has been revoked, suspended, or is past its expiration date, TSA will not recognize it for PreCheck purposes, and you will be sent to standard security screening.

Key Takeaways

  • You must enroll in TSA PreCheck through the TSA website and select your TWIC card as your credential to use it for PreCheck benefits.
  • Your TWIC card must be valid and not expired; a revoked or suspended TWIC will not work for PreCheck access.
  • Using a TWIC for PreCheck is free and does not require a separate PreCheck card or an in-person enrollment appointment.
  • At the airport, present your TWIC card at PreCheck security lanes just as you would present a PreCheck card or Real ID.

How to enroll in TSA PreCheck with your TWIC

Go to the official TSA PreCheck enrollment website at tsa.gov/precheck. Click the "Enroll Now" button and create an account or log in if you already have one. You will be asked to provide your name, date of birth, contact information, and passport or driver's license details.

When you reach the section asking which credential you want to use, select "TWIC" from the dropdown menu. Enter your TWIC card number — this is the 12-digit number printed on the front of your card. The system will verify that your TWIC is valid and active in the DHS database. If your TWIC is current, the enrollment will proceed. If it is expired or revoked, you will see an error message and will need to renew your TWIC before you can use it for PreCheck.

Complete the remaining enrollment steps, including a background check authorization. There is no fee when you use a TWIC for PreCheck enrollment. Once your enrollment is approved — which usually takes a few business days — your TSA PreCheck benefits are active when ready, and you can use your TWIC card at airport security.

What to do at airport security with your TWIC

When you arrive at the airport, look for security lanes marked "TSA PreCheck" or "PreCheck." Present your TWIC card to the TSA officer at the checkpoint, along with your boarding pass and a valid photo ID (such as your driver's license or passport). The officer will scan or read your TWIC to confirm your PreCheck status.

Once verified, you will be allowed to proceed through PreCheck screening, which means you can keep your shoes, belt, and light jacket on; leave your laptop and liquids bag in your carry-on; and move through the line faster than standard security. PreCheck lanes typically have shorter wait times, especially during off-peak hours.

If the TSA officer cannot verify your PreCheck status, you will be directed to standard security screening. This can happen if your TWIC has been revoked, suspended, or if there is a system error. If this occurs, contact TSA at 1-866-289-9673 after your flight to report the issue.

When your TWIC expires or is revoked

TWIC cards are valid for five years from the date of issue. Before your card expires, you should renew it through the Transportation Security Administration's TWIC program. You can check your TWIC expiration date on the front of the card — it is printed below your photo.

If your TWIC is revoked or suspended for any reason — such as a criminal conviction, immigration status change, or security concern — your TSA PreCheck access will be revoked at the same time. You will not receive a separate notification from TSA; you will only discover the problem when you try to use your TWIC at airport security.

If your TWIC has been revoked and you still need PreCheck access, you can enroll in standard TSA PreCheck using a different credential, such as a Real ID driver's license or passport. This requires paying the standard PreCheck fee and visiting an enrollment center in person.

Difference between TWIC and TSA PreCheck

TWIC is a physical credential issued by DHS for workers in transportation and port security roles. It proves your identity and that you have passed a background check for access to find areas of ports, airports, and other transportation facilities. TWIC is required by law for certain jobs; it is not optional for those workers.

TSA PreCheck is a separate program that speeds up airport security screening for passengers. It is optional and available to any U.S. citizen or permanent resident who passes a background check. Most people pay $78 to $85 for a five-year PreCheck membership and enroll at a dedicated enrollment center.

The TSA allows people with valid TWIC cards to use that credential for PreCheck purposes instead of paying for a separate PreCheck membership. This is a benefit for transportation workers who already have TWIC and travel frequently as passengers. If you have a TWIC but do not enroll it in TSA PreCheck, you will not receive PreCheck benefits at airport security — you will go through standard screening like any other passenger.

What happens if your TWIC card is lost or stolen

If your TWIC card is lost or stolen, you should report it to the TWIC program when ready by calling 1-866-347-8942 or visiting the TWIC website. The card will be deactivated in the system, and you will need to explore for a replacement card.

Until you receive your replacement TWIC, you cannot use a TWIC for TSA PreCheck access. If you need to travel by air during this time, you have two options: enroll in standard TSA PreCheck using a Real ID or passport (which requires an in-person appointment and a fee), or go through standard airport security screening without PreCheck benefits.

Frequently Asked Questions

Do I need to pay for TSA PreCheck if I have a TWIC card?

No. If you have a valid TWIC card and enroll it in TSA PreCheck through the TSA website, there is no fee. You only pay the standard PreCheck fee if you enroll using a different credential, such as a Real ID driver's license or passport.

Can I use my TWIC card for PreCheck if it is about to expire?

Your TWIC must be valid and not expired to use it for PreCheck. If your card expires within the next few months, you should renew it before your current card reaches its expiration date. Once your TWIC expires, TSA will no longer recognize it at airport security.

What if TSA says my TWIC is not valid when I try to use it at security?

This usually means your TWIC has been revoked, suspended, or there is a system error. Ask the TSA officer to check the status. If your TWIC is no longer valid, you will need to go through standard security screening. Contact TSA at 1-866-289-9673 after your flight to find out why your card was rejected.

Can I use my TWIC for PreCheck at every airport?

Yes. Any airport in the United States that has TSA PreCheck lanes will accept a valid TWIC card for PreCheck access. However, not all airports have dedicated PreCheck lanes. If your airport does not have a PreCheck lane, you will go through standard security screening.

What if I lose my TWIC while traveling?

Report the loss to the TWIC program as soon as possible by calling 1-866-347-8942. Your card will be deactivated. For your return flight, you will need to go through standard airport security using your passport or driver's license. When you get home, explore for a replacement TWIC card.
