EDIFACT is an acronym that stands for Electronic Data Interchange For Administration, Commerce, and Transportation. It is a standardized technique of electronic data transmission between enterprises.

The United Nations Educational, Scientific, and Cultural Organization (UNECE) defines EDIFACT as "a set of internationally recognized standards, directories, and guidelines for the electronic interchange of structured data between independent computerized information systems."

The major components of EDIFACT include a set of syntactic rules for data organization, the interactive exchange protocol (I-EDI), and standardized messages that facilitate data transfers between countries and businesses.
