UID register

The UID register kept by the FSO is a central database used exclusively to identify enterprises. The data it contains are limited to the minimum necessary for identification.

All enterprises active in Switzerland are included in the UID register. Information on the enterprises can be accessed by the administration (UID services), by the enterprise itself and, to some extent, by the public.

Core properties and additional properties

The data contained in the UID register are divided into core and additional properties. Different access rights exist for these two categories. The core propertiescan be accessed by the public, the additional ones only by the administration.

Core properties

An enterprise’s core properties consist of the name and address as well as information on whether the enterprise is registered in the commercial register or the VAT register. An additional name (e.g. a job title), which the enterprise itself can make known, is also considered to be a core property.

The core properties of enterprises that are registered in a public register (e.g. the commercial register) can always be accessed by the public in the UID register. Enterprises that are not registered in a public register can publish their core properties themselves.

Additional properties

Additional properties are used to identify UID entities more accurately. They provide information on the enterprises economic activity (NOGA code), the legal form and the language of correspondence. They also make it possible to register an alternative address. Only the administration has access to them.
