ANSI X12

ANSI X12 was developed for the American National Standards Institute (ANSI) by the Accredited Standards Committee (ASC) in 1979. The aim was to develop uniform standards for inter-industry electronic exchange of business transactions. ANSI X12 was originally conceived to support businesses across different industry sectors in North America. The ANSI X12 standard is now used worldwide by over 300,000 companies.

ANSI X12 is similar to EDIFACT in that each EDI document is made up of multiple segments. Each segment is composed of a sequence of elements.
