Transportation Worker Identification Credential (TWIC)

A Transportation Worker Identification Credential (TWIC) is a tamper-resistant biometric identification card issued by the Transportation Security Administration (TSA). Workers need a TWIC for unescorted access to secure areas of maritime facilities and vessels regulated under the Maritime Transportation Security Act (MTSA), and the U.S. Coast Guard enforces its use at those sites.

TWIC matters because workers without a valid card cannot enter secure areas of ports, terminals and regulated vessels on their own. For employers, an expired or missing card can mean a driver turned away at the gate, a contractor who cannot start work or a missed delivery.

What Is a TWIC?

The TWIC program was created after the September 11 attacks to make sure that people with unescorted access to sensitive maritime areas have passed a federal security threat assessment. TSA runs the enrollment and background check under 49 CFR Part 1572, and the Coast Guard sets the access control requirements for facilities and vessels in 33 CFR Parts 101 to 106.

A TWIC shows that the holder has passed TSA's security threat assessment. It does not by itself grant access. Each facility or vessel owner still decides who may enter, based on its security plan and business need.

Who Needs a TWIC?

A TWIC is generally required for anyone who needs unescorted access to secure areas of MTSA-regulated facilities, vessels and outer continental shelf facilities. Common examples include:

• Truck drivers who pick up or deliver cargo inside port terminals.
• Longshore workers, terminal operators and facility employees.
• Contractors, such as maintenance, construction and environmental workers, who work inside secure areas.
• Many merchant mariners who hold Coast Guard credentials, although a 2018 federal law exempted some mariners who do not need unescorted access to secure areas.
• Facility security officers and other security personnel.

Many drivers who need a TWIC also hold a commercial driver's license, covered on our CDL requirements page, and some hold a hazardous materials endorsement (HME), which requires a similar TSA background check.

How the Security Threat Assessment Works

TSA's security threat assessment checks the applicant's criminal history, immigration status and terrorism-related records. Certain crimes are permanent disqualifiers, such as espionage, treason and terrorism-related offenses. Others are interim disqualifiers that apply for a set period after conviction or release from incarceration. Applicants who are disqualified can appeal if they believe the records are wrong, or apply for a waiver in many cases. The full list of disqualifying offenses is in 49 CFR 1572.103.

Validity, Fees and Renewal

• Validity: a standard TWIC is valid for five years.
• Reduced fee: applicants who hold a valid HME or a FAST card may qualify for a reduced fee. In that case the TWIC expires on the same schedule as the HME or FAST card rather than five years from enrollment.
• Fees: TSA sets enrollment, renewal and replacement fees, and they change from time to time. Check the official TSA TWIC page for current amounts before you enroll.
• Online renewal: U.S. citizens, U.S. nationals and lawful permanent residents may be able to renew online, at a lower fee, starting up to one year before the card expires and up to one year after. Others must renew in person.

Escorts, New Hires and Card Readers

Escorts: people without a TWIC can enter secure areas only with an escort. In restricted areas, escorting generally means side-by-side accompaniment. In other secure areas, monitoring may be allowed if it is sufficient to observe the person, and the facility security plan sets the details.

New hires: Coast Guard rules allow a facility to give newly hired employees who have applied for a TWIC limited access to secure areas for a short period, generally up to 30 consecutive days, under specific conditions in the security plan.

Card readers: the Coast Guard's TWIC reader rule requires electronic card checks at certain higher-risk facilities and vessels. Implementation for some facilities that handle certain dangerous cargoes in bulk has been delayed to May 8, 2029, so check whether your sites are affected.

How to Apply for a TWIC Step by Step

1. Confirm the need. Check with the employer or facility whether the job requires unescorted access to secure areas.
2. Pre-enroll online. Start the application through TSA's enrollment website to save time at the enrollment center.
3. Schedule an appointment. Choose a TSA enrollment center, since walk-in availability varies.
4. Bring the right documents. Bring the identity and immigration documents TSA lists, plus an HME or FAST card if you are applying for the reduced fee.
5. Complete enrollment. Provide fingerprints and a photo, and pay the fee.
6. Wait for the security threat assessment. Track your status online and respond quickly to any TSA letters.
7. Receive and activate the card. Pick up or receive the card as directed and confirm your PIN if required.
8. Track the expiration date. Plan to renew well before the card expires.

Common Mistakes to Avoid

• Waiting until the card is about to expire to renew, which can leave workers unable to access sites.
• Not reporting a lost or stolen card to TSA promptly.
• Assuming a TWIC alone gives access to every port, when each facility controls its own access.
• Bringing incomplete or incorrect identity documents to enrollment.
• Employers not tracking which workers and contractors hold valid cards.

How SMS360 Helps

SMS360's Training Management module can store credential records such as TWIC cards alongside training records, with reminders before expiration dates. For drivers, Driver Qualification Files keep TWIC information with the rest of the driver qualification file, and Analytics & Reports can show which credentials are expiring soon across the workforce.

Frequently Asked Questions

How long is a TWIC valid?

A standard TWIC is valid for five years. If you enrolled at the reduced fee based on an HME or FAST card, the TWIC expires on a schedule tied to that credential.

Can I renew my TWIC online?

U.S. citizens, U.S. nationals and lawful permanent residents may be eligible to renew online from one year before to one year after expiration. Others must renew in person at an enrollment center.

Does a TWIC let me into any port?

No. A TWIC shows you passed TSA's security threat assessment, but each facility and vessel decides who may enter based on its security plan and business need.

Is a TWIC the same as a hazmat endorsement?

No. Both require a TSA security threat assessment, but the HME is added to a CDL so a driver can haul placarded hazardous materials, while a TWIC is for unescorted access to secure maritime areas. Holding a valid HME may qualify you for a reduced TWIC fee.
