A TWIC card is the federal ID that lets you walk into the secure areas of U.S. ports, terminals and regulated vessels without an escort. You apply by pre-enrolling online, visiting an enrollment center for fingerprints and a photo, paying the fee and passing a TSA background check. The card is valid for five years.
If a job offer at a terminal, a trucking contract with a port or a Coast Guard license application has put "TWIC required" in front of you, this guide walks through the whole process. It covers who needs the card, what to bring, the current fees, how renewal works online, and what happens if something in your record triggers a denial.
What a TWIC Card Is and Who Needs One
TWIC stands for Transportation Worker Identification Credential. According to the TSA program page, the Maritime Transportation Security Act requires it for workers who need access to secure areas of the nation's maritime facilities and vessels. TSA runs the security threat assessment and issues the card, while the U.S. Coast Guard decides how facilities use it at the gate.
In practice, the people who carry a TWIC card fall into a few groups:
- Longshore workers, crane operators and terminal staff at container, bulk and tanker facilities
- Truck drivers who pick up or drop off containers inside port terminals
- Merchant mariners who hold a Coast Guard credential
- Contractors, surveyors, pilots, vendors and repair crews who work on regulated vessels or inside secure terminal areas
For mariners, the card is tied directly to the license. Under federal rules for the Merchant Mariner Credential, failing to obtain or hold a valid TWIC is a basis for denying an original, renewal or upgraded credential. TSA puts it simply: most mariners licensed by the Coast Guard also require a TWIC.
If your path runs through a license, our guide to getting hired in the merchant marine shows where the TWIC fits among the other documents.
TWIC Card Requirements: Who Is Eligible
You may apply if you are a U.S. citizen, a lawful permanent resident, a naturalized citizen, or a nonimmigrant, asylee or refugee in lawful status. Noncitizen workers in lawful nonimmigrant status generally need employment authorization as well.
Applicants can be turned down for two broad reasons: incomplete or false information on the application, and disqualifying criminal offenses or other factors that the background check turns up. The offense rules are specific enough that they get their own section further down.
There is also a route for some foreign workers. TSA describes a TWIC annotated B-1 visa for people who meet the State Department's requirements for a business visitor visa and bring an official letter from their employer. That letter has to say a TWIC is required for the job and give the type of work, its location and duration, and employer contact details.
One rule catches visa holders by surprise. The card belongs to the federal government, and an employer must collect it and return it to TSA when a worker's visa expires.
What You'll Need Before You Apply
Gather these before your enrollment appointment so the visit takes one trip:
- Identity documents: a current U.S. passport on its own, or a driver's license together with a birth certificate. TSA publishes a longer list of other acceptable documents for applicants who have neither combination.
- Immigration documents, if you are not a U.S. citizen
- A payment method: credit card, money order, company check, or certified or cashier's check
- A commercial driver's license with a hazardous materials endorsement, or a FAST card, if you want the reduced fee
- A mailing address where the card can be delivered, or a plan to pick it up at the center
Give yourself time. TSA recommends that every applicant, renewals included, enroll at least 60 days before they need a valid card, and warns that some applicants are currently waiting more than 45 days.
How to Apply for a TWIC Card in 6 Steps
Step 1: Pre-enroll online
Start the application on the TSA Enrollment by IDEMIA website. Pre-enrollment is optional, since the whole process can be done at a center, but entering your details in advance shortens the in-person visit.
Step 2: Book an appointment
Schedule a slot online or by calling 1-855-347-8371, weekdays from 8 a.m. to 10 p.m. Eastern. Walk-ins are accepted at most centers, but appointments take priority. If the nearest center is booked out, TSA suggests trying another center in the same area.
Step 3: Visit the enrollment center
At the center you show your documents, have your fingerprints taken and sit for a facial photo. New applicants have to complete this step in person; there is no fully online first enrollment.
Step 4: Pay the fee
The fee is non-refundable and covers the full five years of the card. Current amounts are in the next section.
Step 5: Wait for the background check
TSA's stated goal is a response within 60 days of receiving your enrollment information. It can take longer if your fingerprints were hard to capture. You can check progress at any time on the IDEMIA service status page or by phone.
Step 6: Receive the card
After approval you get a phone or email notification. The card should then arrive within 10 days, either at your home address or at the enrollment center you chose. You do not receive the card on the day you enroll; every card is printed and mailed from a central facility.
How Much a TWIC Card Costs
TSA's enrollment provider raised its fees on October 1, 2026, because the FBI raised its own fingerprint fee. The new amounts, posted in the IDEMIA enrollment notices, are:
| Service | Fee from October 1, 2026 |
|---|---|
| New enrollment | $127 |
| Reduced-rate enrollment (HME or FAST holders) | $93 |
| Online renewal | $119 |
| In-person renewal | $127 |
| Card replacement | $60 |
Some TSA pages still show the older amounts of $124 for enrollment and $116 for online renewal, so do not be surprised by the difference at the counter. The reduced rate exists because you have already passed a comparable security threat assessment; you have to present a valid commercial driver's license with a hazardous materials endorsement, or a FAST card, to qualify.
A TWIC also opens one extra door. TSA says many TWIC holders meet the criteria for TSA PreCheck and may be eligible for expedited airport screening using the credential they already have.
TWIC Card Renewal: Online or In Person
A TWIC card is valid for five years from the date it is issued. You can renew online up to one year before the expiration date printed on the card and up to one year after it expires. Past that one-year window, you are treated as a new applicant and go through in-person enrollment again.
Online renewal has two conditions. You have to be a U.S. citizen, a U.S. national or a lawful permanent resident, and your name has to match your original enrollment. If you changed your name since then, call the help center at 1-855-347-8371 to update it before you start, according to the TSA TWIC FAQ.
Anyone who is not eligible for online renewal can still renew in person by following the same steps as a new applicant. Renewing online is also the cheaper route, $119 against $127 at a center.
Plan the renewal like a new application. The same 60-day lead time applies, and a card that lapses while you wait can keep you off a terminal or delay a mariner credential renewal that depends on it.
Disqualifying Offenses, Appeals and Waivers
The background check looks at criminal history, immigration status and mental capacity. The criminal rules are set out in 49 CFR 1572.103 and come in two tiers.
Permanent disqualifying offenses
A conviction, or a finding of not guilty by reason of insanity, for any of these felonies disqualifies you no matter how long ago it happened: espionage, sedition, treason, terrorism, a crime involving a transportation security incident, improper transportation of hazardous materials, unlawful dealing in explosives, murder, bomb threats against public places or infrastructure, and certain racketeering violations tied to those crimes.
Interim disqualifying offenses
A second list counts only if you were convicted within seven years of applying, or released from incarceration for it within five years. It includes weapons offenses, extortion, fraud and identity fraud, bribery, smuggling, immigration violations, drug distribution or importation, arson, kidnapping, rape, assault with intent to kill, robbery, fraudulent entry into a seaport, other racketeering violations, and conspiracy or attempt to commit any of them. Welfare fraud and passing bad checks do not count as fraud for this purpose.
What to do if TSA denies you
A first denial is not the end of the road. You can appeal if the record is wrong, request a waiver if it is accurate, or both. If an arrest never led to a conviction, you have 60 days to send TSA written proof.
A waiver request is due no later than 60 days after TSA serves its final determination. TSA weighs the circumstances of the offense, any restitution, mitigation such as completed treatment programs, and court or medical records. The most serious offenses, espionage, sedition, treason and terrorism, cannot be waived.
TWIC Readers: How Facilities Check Your Card
Electronic readers are still not required at many regulated facilities, where the card is checked by eye. A 2016 Coast Guard rule required electronic TWIC readers at the highest-risk facilities and vessels, known as Risk Group A, but that requirement has been pushed back several times.
A July 2026 GAO report found that the Coast Guard has delayed parts of the reader rollout four times and the full rule twice. Facilities that handle certain dangerous cargoes in bulk and transfer them to or from vessels now have until May 8, 2029. That delay does not cover facilities that receive vessels certificated to carry more than 1,000 passengers.
Even without a reader mandate, TSA stepped up its own TWIC enforcement operations at regulated facilities in 2026, using electronic readers to look for altered, counterfeit or tampered cards. A card on TSA's canceled card list is no longer valid, and that list also includes cards replaced as lost, stolen or damaged.
Troubleshooting Common TWIC Problems
Most problems after enrollment fall into a handful of situations, and TSA has a set answer for each.
Your card never arrived. You have 60 days after the approval notification to report non-receipt through the enrollment website or by phone. Miss that window and you pay the $60 replacement fee.
Your card is lost or stolen. Report it by phone or order a replacement online. If you find the old card later, it is no longer valid; destroy it or mail it to the address on the back. While you wait for the replacement, Coast Guard policy allows workers who meet certain conditions to keep accessing a regulated facility, one of which is a receipt showing you ordered the replacement.
Your status has not changed in weeks. TSA notes that difficulty capturing your fingerprints at enrollment can lengthen the wait. Check the status page first, then call the help center.
You no longer meet the eligibility rules. You have to report the disqualifying condition to TSA and surrender the card, by mail or at an enrollment center.
You have an older card design. TSA began issuing the NexGen card in July 2018, but older cards stay valid until their printed expiration date. You do not need to replace a valid card, though you can for the replacement fee.
Working at a Port Once You Have Your TWIC
The card gets you through the gate, but much of port work is waiting on ships. A drayage driver lined up for a container pickup, or a lashing crew scheduled around a vessel arrival, loses hours when a ship runs late, and port congestion makes those delays common.
Primo Nautic tracks vessels in real time from AIS data and shows two arrival estimates side by side: the ETA the captain reports and an AI-calculated route ETA, with a confidence score. A widening gap between the two is worth watching before you head to the terminal.
It also sends delay notifications and arrival alerts, so you can plan a terminal visit around the ship rather than the schedule printed weeks earlier. You can find any vessel by name, MMSI or IMO number.
For mariners, the people at home often follow the same ship. Primo Nautic has a tracking purpose for loved ones working at sea, so a partner can see where the vessel is and what the weather is like there.
Conclusion
A TWIC card is required for unescorted access to secure areas of U.S. maritime facilities and regulated vessels, and most Coast Guard licensed mariners need one too. New applicants pre-enroll online, visit an enrollment center for fingerprints and a photo, pay $127 from October 1, 2026, and wait up to 60 days for the background check.
The card lasts five years. U.S. citizens, nationals and permanent residents can renew online from a year before expiry to a year after it. Start any application or renewal at least 60 days before you need the card. If the background check turns up a problem, an appeal or waiver is often possible, and the deadline to file is 60 days.
