X12 EDIFACT Mapping

In 1979, the American National Standards Institute chartered the Accredited Standards Committee X12 to develop uniform standards for interindustry electronic exchange of business transactions-electronic data interchange
In 1986, the United Nations Economic Commission for Europe approved the acronym "UN/EDIFACT" which translates to United Nations Electronic Data Interchange for Administration, Commerce and Transport. UN/EDIFACT is an international EDI standard designed to meet the needs of both government and private industry.
The UN/EDIFACT Working Group, a permanent working group of the United Nations Centre for Trade Facilitation and Electronic Business, develops and maintains UN/EDIFACT
X12 is used in the USA and by U.S. organizations worldwide. Much of the rest of the world uses the EDIFACT messages.
