The ANSI ASC X12 standard for Electronic Data Interchange (EDI), also referred to as ASC X12, is the EDI standard most widely used in the US and Canada. The group that has sponsored it since 1979, the American National Standards Institute Accredited Standards Committee, includes over 3,000 experts from more than 350 countries.
EDI transaction codes, sometimes called transaction sets or T-sets, correspond to a specific type of electronic business document, such as an invoice or a purchase order. There are many different documents that you might exchange with your trading partners, and many more specialized transaction sets that are not used as commonly.
This document provides a list of ANSI X12 Transaction Sets that correspond to supply chain logistics activities. The X12 standard organizes these transaction sets into series, according to the transportation or business document activities they support.
