SCAC

A unique two to four letter identifier assigned by the National Motor Freight Traffic Association (NMFTA) to transportation companies operating in North America. SCAC codes standardize carrier identification across the logistics industry, enabling seamless communication between shippers, warehouses, and transportation providers.

In warehouse operations, SCAC codes are essential for accurate shipment tracking, carrier performance analysis, and automated data exchange through EDI systems. When integrated with WMS platforms, these codes streamline carrier selection, rate shopping, and shipment visibility by providing a consistent reference point across all logistics partners. The associated class of service designation further specifies the transportation method—such as ground, air, or expedited delivery—helping warehouse managers optimize shipping decisions based on cost and transit time requirements.

For example, “UPSN” identifies UPS Next Day Air service, while “UPGF” represents UPS Ground Freight, allowing precise carrier and service level selection during order fulfillment processes.
