United Nations/Electronic Data Interchange for Administration, Commerce and Transport (UN/EDIFACT) is the international EDI standard developed under the United Nations.
In 1987, following the convergence of the UN and US/ANSI syntax proposals, the UN/EDIFACT Syntax Rules were approved as the ISO standard ISO 9735 by the International Organization for Standardization.
The EDIFACT standard provides:
- a set of syntax rules to structure data
- an interactive exchange protocol (I-EDI)
- standard messages which allow multi-country and multi-industry exchange
The work of maintenance and further development of this standard is done through the United Nations Centre for Trade Facilitation and Electronic Business ( UN/CEFACT) under the UN Economic Commission for Europe, in the Finance Domain working group UN CEFACT TBG5.
