The Transportation Worker Identification Credential, commonly referred to as TWIC, is a security identification card issued by the Transportation Security Administration, or TSA. It is designed for individuals who require unescorted access to secure areas of maritime facilities and vessels regulated by the United States Coast Guard. The TWIC program aims to enhance security by ensuring that Transportation Workers undergo thorough background checks, including a review of criminal history and immigration status. The credential is important for various professionals in the transportation sector, including port workers, truck drivers, and maritime personnel, as it demonstrates that they have met the necessary security criteria to work in sensitive areas.
