About standards

Standards are necessary for effective postal operations and to interconnect the global postal network.

Standards Board

The UPU's Standards Board develops the technical standards and EDI message specifications that facilitate the exchange of operational information between Posts.

It also coordinates UPU standardization initiatives with those of other international standardization bodies, and works closely with Posts, customers, suppliers and many international organizations to this end.

The Standards Board also ensures that coherent standards are developed in areas such as electronic data interchange (EDI) and mail encoding.


All Standards that have reached a particular stage within the Standards Approval process are published in either the UPU Technical Standards or the UPU EDI Messaging Standards.

A listing of all published standards together with a very brief overview of their content can be found in the Catalogue of UPU standards.

Many standards refer to code lists.
