UN/EDIFACT message types
A UN/EDIFACT message type is one business document -- a purchase order, a despatch advice, an invoice -- defined once by the standard and then republished, with revisions, in each directory version. This page lists every message type in the library. Open one to see what it is for and which directory versions define it.

Each message type links to its own page, listing every directory version that publishes it. If a trading partner has named a message you do not recognise, find it here first: the name is the same in every version, and only the segment detail changes between them.

Frequently asked questions
What is a UN/EDIFACT message type?
One business document defined by the standard, identified by a six-letter name such as ORDERS or INVOIC. The name stays the same across every directory version; what changes between versions is the segment detail inside it.
How many UN/EDIFACT message types are there?
This library publishes 205 message types across 11,035 version-specific specifications. Most trading relationships use a handful: an order, an order response, a despatch advice and an invoice.
Which version of a message should I use?
The one your trading partner specifies. A partner tells you both the message and the directory, for example D96A ORDERS, because the segments differ between versions. Open a message type here to see every version that defines it.
