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.

UID newsletter

The UID team compiles a newsletter for interested administrative units and enterprises.
