PORT SECURITY COMPLIANCE
TWIC-Certified Drayage Carriers
TWIC stands for Transportation Worker Identification Credential, a tamper-resistant biometric card issued by the Transportation Security Administration (TSA) that grants workers unescorted access to secure areas of US maritime facilities. All commercial motor vehicle drivers who enter secure port areas to pick up or deliver cargo must hold a valid TWIC card. A drayage carrier whose drivers lack TWIC credentials cannot complete terminal gate-in and gate-out procedures at most US container ports, making TWIC certification a fundamental requirement for any carrier operating in the maritime freight market.
What is TWIC and who needs it?
The TWIC program was established under the Maritime Transportation Security Act of 2002, passed following the September 11 attacks to improve security at US maritime facilities. The credential is required for any worker who needs unescorted access to secure areas of a maritime facility covered by the Maritime Transportation Security Act, including commercial truck drivers making terminal pickups or deliveries. To obtain a TWIC card, applicants must submit to a TSA security threat assessment, which includes a criminal background check, immigration status verification, and checks against federal terrorist watchlists. The process typically takes several weeks from application to card issuance. TWIC cards are valid for five years and must be renewed before expiration. The practical impact on drayage carriers is significant: every driver in the fleet who will enter port terminals must hold a current TWIC card. Carriers with multiple drivers must manage an ongoing TWIC renewal calendar to avoid any driver being denied gate access due to an expired credential. Carriers who operate only at inland intermodal rail ramps (such as Chicago) do not require TWIC, as the TWIC mandate applies specifically to maritime security zones. However, carriers working at seaports universally require it. When a carrier is described as "TWIC-certified," it means their driver pool holds current TWIC credentials and the carrier has the internal processes to maintain ongoing compliance.
Why TWIC compliance matters when booking drayage
From a freight forwarder's or shipper's perspective, the consequences of booking a carrier whose drivers lack current TWIC credentials are immediate and costly. If a driver arrives at the terminal gate without a valid TWIC card, they are denied entry. The container sits at the terminal, accruing demurrage. The carrier must send a different driver, which adds delay, or the shipper must find an alternative carrier urgently, usually at premium rates. These failures are entirely avoidable by verifying TWIC compliance before booking. TWIC compliance is also a signal of broader operational discipline: carriers that maintain current TWIC credentials for their full driver roster have the internal compliance management systems in place to track expiring certifications, manage renewals, and keep their workforce port-ready. This same discipline typically extends to FMCSA safety compliance, UIIA enrollment management, and other operational requirements. Beyond container drayage, TWIC is required for any driver delivering to petroleum terminals, LNG facilities, and other regulated maritime infrastructure. Carriers with TWIC credentials across their fleet can serve a broader range of industrial customers in the maritime supply chain. For shippers with supply chains that touch multiple US ports, requiring TWIC compliance from all drayage carriers simplifies vendor management and eliminates a category of gate-related delay risk.
TWIC Compliance Requirements
- TSA Background Check: Each driver must pass a TSA security threat assessment including criminal background, immigration status, and watchlist screening before a TWIC card is issued.
- Five-Year Validity: TWIC cards expire after five years. Carriers must track renewal dates and ensure no driver enters a secure port area with an expired credential.
- Card Readers at Terminals: Some ports use TWIC card readers at gates for electronic verification. Carriers must ensure their drivers understand how to present credentials at both visual inspection and reader-enabled gates.
- Applies to Maritime Facilities Only: TWIC is required at ports and other MTSA-regulated facilities. Inland intermodal rail ramps (Chicago, Memphis, etc.) do not require TWIC.
How to find TWIC-certified carriers on DrayLocator
DrayLocator lists drayage carriers across all major US container ports with FMCSA-safer/" style="color:inherit; text-decoration:underline; text-decoration-style:dotted; text-underline-offset:2px;">FMCSA SAFER data updated daily. Use the port-specific directory pages to find carriers operating near your terminal. Each carrier listing shows their operating authority, fleet size, and driver count from FMCSA records. When evaluating a carrier's TWIC compliance, always confirm directly with the carrier that their current driver roster holds valid, non-expired TWIC credentials before booking. For high-volume shippers, including a TWIC credential verification step in your carrier onboarding checklist is the most reliable way to prevent gate-related delays.

What does TWIC stand for?
TWIC stands for Transportation Worker Identification Credential. It is a tamper-resistant biometric identity card issued by the US Transportation Security Administration (TSA) that grants the holder unescorted access to secure areas of US maritime facilities, including container terminals, petroleum terminals, and other ports regulated under the Maritime Transportation Security Act of 2002.
Do all drayage drivers need TWIC?
All commercial vehicle drivers who need unescorted access to secure maritime port areas must hold a valid TWIC card. This includes virtually all drayage drivers making pickups or deliveries at US seaport container terminals. Drivers who only work at inland intermodal rail ramps (such as BNSF or Union Pacific facilities in Chicago) do not need TWIC, as the requirement applies to maritime security zones specifically.
How long does it take to get a TWIC card?
The TWIC application and issuance process typically takes 4 to 6 weeks from submission to card delivery, though it can vary based on TSA processing times and any issues identified in the background check. Carriers should plan ahead and build TWIC renewal cycles into their driver compliance calendar to avoid gaps in port access eligibility.
How do I verify a drayage carrier is TWIC-compliant?
Ask the carrier directly to confirm that all drivers who will be assigned to your terminal pickups and deliveries hold current, non-expired TWIC cards. Request copies of TWIC cards as part of carrier onboarding documentation, or include a TWIC compliance attestation in your carrier agreement. DrayLocator provides FMCSA operating data for carrier verification, but TWIC status must be confirmed directly with the carrier.
