The Standard Carrier Alpha Code (SCAC) is a unique two-to-four-letter code used to identify transportation companies. NMFTA developed the SCAC identification codes in the mid 1960's to facilitate computerization in the transportation industry.

SCACs are required when doing business with all U.S. Government agencies and with many commercial shippers including, but not limited to, those in the automobile, petroleum, forest products, and chemical industries as well as suppliers to retail businesses and carriers engaged in railroad piggyback trailer and ocean container drayage. Carriers who use the Uniform Intermodal Interchange Facilities Access Agreement (UIIA) are required to maintain a valid SCAC. The petroleum industry uses SCACs in their integrated software programs that expedite the movement of bills of lading, pipeline tickets, product transfer orders, and inventory data. Many commercial shippers and receivers utilize SCACs in their freight bill audit and payment systems.
