The UID in general

Since January 2011, each enterprise active in Switzerland has been allocated a unique enterprise identification number (UID). The aim is to eventually reduce the large number of different identifiers used in the administration (e.g. commercial register number or VAT number) and to replace them with a single and unique identifier.

The use of the UID aims to reduce the administrative burden on enterprises and to increase the administration's efficiency.
