Description
Standard Carrier Alpha Code (SCAC)
The Standard Carrier Alpha Code (SCAC) is a unique two-to-four-letter code used to identify transportation carriers and companies. Developed by The National Motor Freight Traffic Association (NMFTA) in the 1960s to help transport carriers computerize their data and records.
The SCAC code allows the registration of your shipping documents (e.g., freight bills, bills of lading, purchase orders, packing lists) within a digital computer system for ease of access. It is vital to keep your computer systems optimized to use SCAC.
Once these records are digital, stakeholders can access important documents related to your company and operations. These digital records also allow you to track your shipment at every stage of the journey. SCAC is mandatory in certain circumstances. It efficiently monitors transportation companies across various transport modes, such as motor vehicles, railway lines, and waterways.
