EDI SCAC, or Standard Carrier Alpha Code, is a standardized code that allows companies to keep track of packages from the SCAC code look up service. The National Traffic Association used standard carrier alpha codes to ID transportation companies like FedEx with the tracking number.
The Standard Carrier Alpha Code is a unique code that was developed by the National Motor Freight Traffic Association to control operations and monitor all transportation services. It effectively allows the National Traffic Association to look through the list of numbers through SCAC code look up. The directory includes an annual release and is updated on a quarterly basis.
