Information for enterprises

The UID simplifies contacts between the local and federal authorities and enterprises and institutions in Switzerland.
When you indicate your enterprise’s UID to an authority, they can automatically retrieve the reference data for your business, provided they are registered as a UID service in the UID register. You do not have to indicate your data every time you contact the authorities (“once only” principle). Furthermore, all authorities connected to the UID register will automatically be informed of changes to your data (e.g. change of address).

Who receives a UID?

Enterprises or institutions receive a UID when they are announced to an authority that is connected to the UID register. The term “enterprise” is understood in its broadest sense and also includes foundations, associations and enterprises governed by public law.

A UID is allocated upon an entry in one of the following registers or an announcement to one of the following authorities:

In the public sector, all communes and cantons have their own UID. At federal level, the Confederation, Departments and Federal Offices have their own UID.
An additional UID is allocated to entities attached to the Confederation, a canton or commune if they are subject to VAT or are themselves a UID service.

Allocation of UID only through authorities (UID service)

An enterprise cannot request its UID directly from the Federal Statistical Office. The enterprise will be automatically allocated the UID once it is announced to an authority that is connected to the UID register.

An enterprise that is registered in a commercial register or in an AHV/AVS compensation fund, for example, or that is subject to VAT, is automatically entered in the UID register and registered free of charge. The enterprise will then receive an official letter with its UID from the Federal Statistical Office.
