| Don’t get denied at the gate. Learn why every port and intermodal carrier needs a SCAC code |
Picture this: You’ve driven hours to the terminal, paperwork in hand, but the gate guard says, “You’re not in the system.”
Without a valid Standard Carrier Alpha Code® (SCAC®), your truck—and your shipment—aren’t going anywhere.
What Is SCAC?
A SCAC is a unique two-to-four-letter identifier assigned by the National Motor Freight Traffic Association, Inc. (NMFTA) to transportation companies operating in the United States (U.S.).
It’s more than just a code; it’s your key to operate, access ports, and be recognized by shippers, brokers, and customs systems.
A valid SCAC is required to:
- Identify carriers in U.S. Customs filings;
- Facilitate Electronic Data Interchange (EDI) transactions; and
- Grant terminal and port access for freight pickup and delivery.
What Happens If You Don’t Have One?
Showing up at a port without a valid SCAC can lead to:
- Gate Denial: Most U.S. ports and intermodal terminals won’t let you in without it.
- Customs Delays: No SCAC means no clearance for your cargo, and your freight stays put.
- Appointment Rejection: Terminals may refuse to load/unload your freight.
Bottom line: No SCAC, no access.
What to Do Before You Arrive at a Port or Intermodal Terminal
Here’s what every driver, dispatcher, and carrier should do before heading out:
1. Confirm Your Appointment
- Double-check gate time, terminal location, and entry instructions.
2. Prepare Your Paperwork
- Bill of Lading (BOL);
- Delivery or pickup reference number; and
- Any special shipper/receiver instructions.
3. Verify Your Credentials
- Valid driver’s license;
- Transportation Worker Identification Credential (TWIC) card (if required); and
- Company ID or carrier credentials and active SCAC.
If your company operates under another carrier’s authority, confirm their SCAC is active and listed correctly.
Where to Get a SCAC
- NMFTA: Apply at scaccode.com — the official NMFTA application site.
- Carrier or Dispatch Team: They should have your company’s SCAC.
- Broker or Terminal Communications: Often include SCAC requirements.
Bottom Line
Before you roll up to the port, make sure your SCAC is:
- Registered, active, and correctly listed on all documentation.
- Ensure your team (dispatchers, brokers, drivers) uses the same SCAC consistently.
It’s a small code with big consequences—don’t leave it to chance.
