Contact us / Classifications Hotline
We are constantly trying to improve the content of our website. If you have any suggestions or questions, please let us know.
You can also contact us if you need assistance with proper classification of activities, products etc. in one of the classifications supported by the United Nations.
The United Nations Statistics Division is currently undergoing a restructuring, which will also affect the work on statistical classifications. The Industrial and Energy Statistics Section, which was previously responsible for the coordination of classifications work, does no longer exist and it is planned that individual Branches of UNSD take over the responsibility for classifications applicable to their work areas. The UN Classifications Hotline will serve as a portal to direct your questions and comments to the appropriate contacts in the different Branches of UNSD.
The Classifications Hotline can be reached by e-mail, fax or regular mail:
