This specification provides the definition of the Request for document message (REQDOC) to be used in Electronic Data Interchange (EDI) between trading partners involved in administration, commerce and transport.


1.1. Functional definition

A message to enable a party request the sending, or re-sending, of data, either as a document or message, or in some other agreed form.

1.2. Field of application

The Request for document message may be used for both national and international applications. It is based on universal practice related to administration, commerce and transport, and is not dependent on the type of business or industry.

1.3. Principles

The message is used to request a document to be sent, either electronically or otherwise. Its use should be limited to requesting documents, for which there is no other more specific message already provided (e.g. Request for Quotation).

Parties can request documents on their own behalf, or on behalf of third parties.

The message can be used to request individual documents by identity, or by specifying product and/or other related data to retrieve all relevant documents.

Typical uses of the Request for Document Message are to request information from a data base (e.g. requesting a copy of a test certificate), requesting catalogue data, and requesting statements of account.


See UNTDID, Part 4, Chapter 2.3 UN/ECE UNSM - General Introduction, Section 1.
