Do I Need a SCAC?
Many companies across the freight transportation ecosystem are required—or expected—to have a Standard Carrier Alpha Code® (SCAC™). If you move freight, contract transportation, or interact with shipper or broker onboarding systems, there’s a strong chance you need one.
This page helps you quickly confirm whether a SCAC applies to your operation.
You likely need a SCAC if you:
-
Operate as a motor carrier (Class 8 or Non-Class 8);
-
Work with shippers, brokers, or third-party logistics providers (3PLs) that require a SCAC for onboarding;
-
Haul freight that will be tendered through a transportation management system (TMS)/load platform;
-
Support government or regulated freight workflows (including USPS contractors); or
-
Operate cross-border or within systems that require standardized carrier identifiers.
Common "Yes" Scenarios
-
Owner-operators and small fleets
A SCAC is often required to get onboarded with brokers or shipper programs.
-
Non-CDL box truck/van carriers
A SCAC is commonly required for last-mile and middle-mile contract work.
-
Private fleets
If you tender, broker, or move freight through external platforms, you may need a SCAC for identification.
-
Maritime/ intermodal operations
Many port and maritime workflows require standardized identifiers.
If You're Not Sure
If a shipper, broker, 3PL, government entity, or platform told you a SCAC is required, the simplest path is to apply.
