Information for administrative offices

The UID services are administrative offices of the Confederation, cantons and communes as well as institutions governed by public law (under Art. 3 para.1 let. d BINA). They manage enterprises in their data collections and are regularly in contact with them.

Overview of UID services

The data collections of UID services are kept for different purposes. A hierarchy of the UID services has been established that takes these differences into consideration. If several UID services are registered for an entity, the service that is highest in the hierarchy is the one responsible for that entity. This means that in the UID system, only one UID service is responsible for each enterprise.

The diagram below shows the hierarchy (H1 to H4) of the UID services and to which authority they are affiliated (Confederation, canton or institutions governed by public law):
