Application
If you work at a port, on a vessel, or in any secure maritime facility in the United States, chances are you've heard of the TWIC card. But what exactly is it, who needs one, and how do you get it? This guide covers everything.
TWIC stands for Transportation Worker Identification Credential. It is a federally issued, tamper-resistant smart card that proves the holder has passed a rigorous government security background check and is authorized to access secure areas of U.S. maritime facilities and vessels without an escort.
The TWIC is required by the Maritime Transportation Security Act (MTSA) for workers who need unescorted access to secure areas of the nation's maritime facilities and vessels. Coggno The program is jointly administered by the Transportation Security Administration (TSA) and the U.S. Coast Guard.
The TWIC program originated post-9/11 as part of the Maritime Transportation Security Act of 2002, aimed at bolstering security in the United States' maritime sector. The program officially launched in 2007, with one million workers enrolled by 2009.
The goal was simple: ensure that anyone walking into a sensitive port, dock, or vessel had been thoroughly vetted. Before TWIC, there was no single, standardized security credential for maritime workers across the country.
This is one of the most searched questions — and the answer is broader than most people expect.
A merchant mariner or Coast Guard-credentialed seafarer
A truck driver who enters port terminals (TWIC CDL jobs)
A contractor or vendor with regular access to port facilities
An offshore oil and gas worker at a maritime facility
A government employee or contractor at a sensitive transportation hub
Those seeking unescorted access to secure areas aboard affected vessels, and all Coast Guard credentialed merchant mariners, must obtain
The TWIC card is a tamper-resistant smart card that includes embedded microchips and magnetic stripes storing the holder's fingerprint and photo, facilitating accurate and swift identity verification at checkpoints
The issued card contains an Integrated Circuit Chip (ICC) which stores the holder's information and biometric data. The chip can be read by inserting it into a reader or holding it near a "contactless" reader. There is also a magnetic strip and a linear barcode on the back as alternative reading methods.
The cost of a TWIC card is $125.25 for new applicants, with a $60 fee for replacements. USCG
A reduced rate of $93.00 is available for applicants who present a valid commercial driver's license with a hazardous materials endorsement (HME), or a Free and Secure Trade (FAST) card. TSA
Each TWIC applicant undergoes a security threat assessment. The assessment considers convictions, arrest warrants, and indictments for certain offenses and other background information.
Permanent disqualifiers include convictions for espionage, treason, terrorism, and certain felonies involving transportation security or hazardous materials. An applicant can, however, appeal a denial or apply for a waiver in some circumstances.
A standard TWIC card is valid for five years. You can renew it online through the TSA enrollment portal. Again, plan ahead — apply for renewal well before your card expires to avoid gaps in access that could cost you work.
