About Electronic Data Interchange (EDI)

Electronic Data Interchange (EDI) is the electronic exchange of routine business information by using an agreed-upon file structure.

The file structures are defined with EDI standards for the electronic documents. These uniform electronic formats are referred to as 'standards'. Standards, which are periodically updated, are referenced with versions that specify releases. For example, X12 Version 4010 is version 004, release 010; Version 3050 is version 003, release 050.

EDIFACT (Electronic Data Interchange For Administration, Commerce, and Transport) transitioned to using the D versions starting in the early 1990s. The D versioning system signifies that the release is a directory, updated twice a year, in a specific year.

• D.XXA

  Indicates the first release of the year XX.

  For example, D.21A refers to the first release of the year 2021.

• D.XXB

  Indicates the second release of the year XX.

  For example, D.21B refers to the second release of the year 2021.
