Standard Carrier Alpha Code™ (SCAC®) Product Descriptions

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.

The Standard Carrier Alpha Code is the recognized transportation company identification code used in the American National Standards Institute (ANSI) Accredited Standards Committee (ASC) X12 and United Nations EDIFACT approved electronic data interchange (EDI) transaction sets such as the 856 Advance Ship Notice, the 850 Purchase Order and all motor, rail and water carrier transactions where carrier identification is required. The SCAC is required on tariffs filed with the Surface Transportation Board (STB).

Each Standard Carrier Alpha Code is published by the National Motor Freight Traffic Association, Inc. The SCAC data is available via an online search engine on the internet through SCAC Online. If you require a data download, SCAC data is accessible Quarterly or Daily by either FTP or email, both in UTF8 encoded ASCII format. The record length is 254 characters.
