A Department of Transportation (DOT) number and a Standard Carrier Alpha Code® (SCAC)® aren’t the same, and getting one doesn’t automatically create the other. A DOT number identifies your company in federal transportation records and supports safety monitoring and compliance oversight. A SCAC is a separate, private-sector code issued by NMFTA, so you must apply for it independently once your federal records are active.
The DOT Number: Your Federal Identifier
The Federal Motor Carrier Safety Administration (FMCSA) issue a DOT number. It identifies your company for safety monitoring, compliance reviews, and federal transportation oversight. It is an important early step for carriers entering the industry, but it does not replace any separate registration, authority, or industry-code requirements that may apply.
But here’s the key point: A DOT number does not classify you as a carrier in NMFTA’s system. It confirms that your company is registered in FMCSA’s federal transportation records, but it does not automatically provide a SCAC.
Why a DOT Number Doesn’t Automatically Create a SCAC
The SCAC, or Standard Carrier Alpha Code, is issued by the National Motor Freight Traffic Association® (NMFTA)®. It’s used for:
- EDI transactions;
- Load tendering;
- Billing and rating;
- Customs and international shipping; and
- Carrier identification across transportation systems.
Because FMCSA and NMFTA maintain separate systems, NMFTA must verify your company information before assigning a SCAC. That independent verification is why a DOT number alone is not enough.
The Current Process: Step-by-Step
If your business needs a SCAC, complete the following steps after confirming that your federal records are active and accurate:
Step 1: Confirm That Your Federal Records Are Active
FMCSA must activate your DOT number and operating authority before NMFTA can verify your credentials.
Step 2: Ensure Your Company Information Matches
NMFTA cross-checks your legal name, address, and authority against FMCSA records to confirm accuracy.
Step 3: Apply for Your SCAC
Once your DOT authority is active, you must submit a separate SCAC application through NMFTA’s online portal at https://scaccode.com.
Step 4: Wait for NMFTA Verification
NMFTA reviews your application and confirms your authority before issuing your Standard Carrier Alpha Code.
Step 5: Receive Your SCAC Assignment
After approval, NMFTA assigns your SCAC. Renew it annually to keep it active.
A DOT number is necessary, but not sufficient, to receive a SCAC. The two systems serve different purposes, are managed by different entities, and require separate applications. Once your federal records are active and accurate, apply directly through NMFTA for the SCAC your business needs.
