UN Classifications Registry

The Classifications registry keeps updated information on Statistical Classifications maintained by the United Nations Statistics Division (UNSD).

Rulings, corrections, interpretations and proposals for future revisions are recorded and can be viewed from the 'Registry entries' link on the left. These entries can also be searched or viewed sorted by meetings where they have been discussed or the revision process to which they may relate.
Complete updated structure and explanatory notes (in several languages where available) are shown, indicating all changes made since the original publication. Check the 'Classifications' link in the menu on the left for available languages.
Alphabetical indexes and correspondence tables are available for some classifications. They can be accessed from the left menu and individually for a single code in the classifications.
The section on 'National Classifications' includes information on national practices in the area of classifications, covering activity and product classifications used in countries around the world.
