TWIC Card (Transportation Worker Identification Credential)
The Transportation Worker Identification Credential is a tamper-resistant biometric card issued by the Transportation Security Administration (TSA) that grants unescorted access to secure areas of maritime facilities and vessels regulated under the Maritime Transportation Security Act (MTSA). TWIC cards are required for port truck drivers, longshoreworkers, and other workers who need access to secure port and maritime areas. The program is administered jointly by the TSA and the U.S. Coast Guard.
The TWIC program was established under the Maritime Transportation Security Act of 2002 and the SAFE Port Act of 2006 to ensure that individuals with unescorted access to secure areas of the nation's maritime transportation system have undergone a thorough security threat assessment. While primarily a maritime security credential, the TWIC card is especially relevant to the trucking industry because thousands of truck drivers regularly pick up and deliver freight at port terminals, refineries, and other MTSA-regulated facilities.
To obtain a TWIC card, applicants must visit a TWIC enrollment center for fingerprinting and an in-person identity verification. The TSA then conducts a security threat assessment that includes a criminal history records check, an immigration status check, and a review against the terrorist screening database. The entire enrollment-to-issuance process typically takes 8 to 12 weeks, though expedited processing is sometimes available. Applicants with certain criminal convictions or immigration violations may be permanently or temporarily disqualified.
TWIC cards are valid for five years from the date of issuance and must be renewed before expiration to maintain unescorted access to secure facilities. Because the renewal process also requires a new security threat assessment and can take several weeks, drivers should begin the renewal process at least 60 to 90 days before their card expires. For trucking companies that serve port customers, tracking TWIC card expirations alongside CDL and medical card renewals is essential to avoiding disruptions in freight delivery. A driver with an expired TWIC cannot enter a secure port facility, which can delay loads and damage customer relationships.
