Enterprise Identification Number UID

All active companies in Switzerland are given a standardised business identification number (UID). The use of the UID decreases the administrative burden on businesses and allows for a more efficient collaboration between authorities.

The FSO maintains the UID register to ensure correct allocation, management and use of the UID.

Under The UID in general you will find further information on the purpose and use of the UID, key milestones in the use of the UID as well as on the legal bases and data protection.
