TWIC — and the exemption almost nobody knows about

What a TWIC is

The Transportation Worker Identification Credential, issued by the TSA. It is a biometric card required for unescorted access to secure areas of regulated maritime facilities and vessels. You enrol in person, give fingerprints and a photograph, prove your identity and citizenship, pay TSA's fee, and undergo a security threat assessment under 49 CFR 1572.5.

The general rule

• 46 CFR 10.203(a) — failure to obtain or hold a valid TWIC is a basis for denial of an application.
• 46 CFR 10.209(f) — the Coast Guard will not issue an MMC until it has received proof the mariner holds a valid TWIC.
• 46 CFR 10.235(i) — a mariner denied a TWIC, or whose TWIC was revoked, is ineligible for an MMC.
• 46 CFR 10.237(c) — the Coast Guard will not review a TSA decision to suspend, revoke or deny a TWIC. That appeal goes to the TSA, not to the Coast Guard.

The exemption

Section 809 of the Coast Guard Authorization Act of 2010 let the Coast Guard exempt mariners who do not need unescorted access to a secure area. Policy Letter 11-15 does exactly that, for mariners on vessels that carry no security plan — and the first item on its list is:

Uninspected passenger vessels of less than 100 gross register tons.

That is the whole OUPV population. The letter also covers Subchapter T vessels not on international voyages, and certain towing vessels. The current CG-719B carries a tick-box for the exemption.

CAUTION — Exempt from HOLDING the card — not from ENROLLING Policy Letter 11-15 is explicit. A mariner being issued an initial MMC, or who has never held a TWIC, must still enrol at a TWIC enrolment centre — because that is the only place the Coast Guard can capture the fingerprints it requires. You pay the fee and give the biometrics. What you need not do is return to collect the card.

So: anyone who says "no TWIC needed for an OUPV" is wrong. Anyone who says "you must have the card in hand" is also wrong. Both halves of that sentence get repeated as gospel, and both are half-truths.

Renewal is different

A mariner renewing, who previously held or applied for a TWIC, may skip enrolment and take a name-based security check instead. The NMC's own guidance warns that a name-based check can significantly delay processing — so the convenience is real but it is not free.

Practical

• Enrol early. TSA's stated goal is a response in 30–45 days, and it is a goal, not a promise.
• Bring a current US passport, or a driver's licence and birth certificate.
• The fee is a TSA fee, not a Coast Guard one, and it is separate from the MMC fees entirely.
• If you intend to work on an inspected vessel with a security plan, the exemption does not help you — get the card.
