What is UN/EDIFACT Standard and Messages?

Introduction

UN/EDIFACT (United Nations/Electronic Data Interchange for Administration, Commerce, and Transport is the international standard that was developed by the United Nations). Comprise a set of internationally agreed standards, directo­ries, and guidelines for the electronic interchange of structured data, between independent computerized information systems. The work of maintenance and further development of this standard is done through the United Nations Center for Trade Facilitation and Electronic Business (UN/CEFACT) under the UN Economic Commission for Europe.

EDIFACT has served as the default international EDI standard for several decades and is largely used throughout Europe.

EDIFACT Message Structure

An EDIFACT message represents a single business document. – For example, an ORDRSP file represents a Purchase Order note. Each message has a six-letter identifier that shows the short name of the message.

Any document in the UN / EDIFACT standard has a hierarchical structure. The entire electronic document is called a message. A message consists of data groups combined in some way, for example, a data group describing customs payments, a group of data describing the attributes of documents, etc. In turn, the group consists of typical data segments that describe document attributes in more detail. The standard provides about 200 different types of segments from which messages are composed. The segments themselves also have a hierarchical structure and consist of data elements that can be simple (data field) and composite (usually 2-3 data fields).

The following is the structure of an EDIFACT transmission:

  • Service String Advice
  • Interchange Header
  • Functional Group Header
  • Message Header
  • User Data Segments
  • Message Trailer
  • Functional Group Trailer
  • Interchange Trailer

Conclusion

The UN/EDIFACT standard provides a set of syntax rules to structure, an interactive exchange protocol, and provides a set of standard messages which allow multi-country and multi-industry exchange of electronic business documents. EDIFACT is widely used across Europe, mainly since many companies adopted it very early on. EDIFACT has seen some adoption in the ASPAC region, however, there are currently more XML-based standards being used in this region today.

Frequently Asked Questions

The UN/EDIFACT (United Nations/Electronic Data Interchange for Administration, Commerce, and Transport) standard is an international messaging format developed by the United Nations to facilitate electronic data exchange for various business processes, including administration, commerce, and transport. It defines a set of rules and structures for creating structured messages that enable seamless communication between different computer systems.

The primary purpose of the UN/EDIFACT standard is to establish a common format for electronic data interchange (EDI) among businesses and organizations worldwide. By providing a standardized framework for representing and exchanging business data, the UN/EDIFACT standard helps streamline communication, reduce errors, and enhance efficiency in processes such as procurement, transportation, and customs clearance.

The UN/EDIFACT standard works by defining a set of message types and data elements that represent specific business transactions or information exchanges. These messages are organized into directories and directories into segments, creating a hierarchical structure. Each segment contains relevant data elements, and the messages are formatted using a combination of letters and numbers. When two trading partners want to exchange information, they follow the UN/EDIFACT guidelines to create, send, and receive standardized messages.

Yes, UN/EDIFACT messages are designed to be technology-neutral, meaning they can be implemented and used across various technology platforms and communication methods. While the standard originated in the era of electronic data interchange (EDI) systems, it can still be adapted to modern technologies, such as XML-based formats, web services, and APIs, ensuring seamless integration with contemporary business systems.

UN/EDIFACT messages cover a wide range of business processes. Some common examples include:

  • ORDERS: Used for purchase orders and order responses between trading partners.
  • INVOIC: Used for transmitting invoice information from the seller to the buyer.
  • DESADV: Used for providing details about shipments and deliveries.
  • CUSDEC: Used for customs declarations during international trade.
  • REMADV: Used for transmitting payment instructions and advice.

These messages serve as standardized templates for specific interactions, helping businesses communicate effectively while minimizing errors and discrepancies.
