The Transportation Security Administration on Sunday published its latest set of cancelled Transportation Worker Identification Credentials (TWIC), a move that quietly but materially impacts thousands of long-shore, offshore-energy, and supply-chain professionals who require unescorted access to secure U.S. port facilities.
The November 30 release includes four updated files—digital and “visual” lists plus corresponding integrity hashes—that ports use to sync access-control systems. Workers whose cards appear on the list lose their right to enter secure areas until they resolve underlying issues such as expired documents, security holds, or disqualifying offenses.

Why this matters: TWIC status often determines whether maritime engineers, project managers, and vessel crew can board ships on short notice. A cancelled card can derail a time-critical LNG maintenance call or delay cargo worth millions. Global mobility teams should cross-check employees and contractors against the new list and schedule renewal appointments early; current wait times at IdentoGO enrollment centers average 18 days in major ports.
The update also foreshadows TSA’s upcoming digital-credential pilot, expected in early 2026, that will allow ports to verify TWIC status in real time via a mobile API—reducing reliance on static PDF lists and shrinking the compliance burden for multinational operators.
