Transportation Worker Identification Credential (TWIC)

Who needs a TWIC?


All individuals requiring unescorted access to secure areas of MTSA-regulated facilities and vessels must obtain a TWIC, including:

  • Coast Guard-credentialed merchant mariners;
  • Port facility employees;
  • Long shore workers;
  • Truck drivers;
  • Vessel pilots;
  • Individuals doing work on a towing vessel that pushes, pulls, or hauls alongside a tank vessel; and
  • Other individuals engaged in port security activities, as determined by DHS.

An employer may not require an employee to apply for a TWIC if the employee’s job does not require unescorted access to secure areas of MTSA-regulated facilities or vessels. TWIC applicants must show a good faith need for the TWIC in their application.


In order to obtain a TWIC, an applicant must make an appointment at an enrollment center, visit the enrollment center to complete the TWIC application, provide biographic informatoin and fingerprints, pay the enrollment fee, and sit for a digital photograph. Once the application is processed, the TWIC is mailed directly to the applicant. The Transportation Security Administration (TSA) periodically publishes TWIC Dashboard Reports, which provide the latest TWIC enrollment statistics (e.g., total number of enrollments, active cards, etc.).
