History of EDI ANSI ASC X12 Standard

Way back in the 1960’s railroad companies developed and used inter-company communications. By the 1970s many big grocery retailers started using EDI and proliferated their early form of technology. By 1973 the committee that had been established in the 1960s decided to create a set of standards that all EDI users could use to make the exchange of information seamless. In 1981 these standards eventually became ratified as the EDI ANSI X12 standard in use today.

ASC X12 has sponsored more than 315 X12-based EDI standards and a growing collection of X12 XML schemes for insurance, healthcare, government, transportation, finance, and many other industries.
