UID InfoAbo

For the UID register to be able to fulfil its data hub role, an automatic notification system has been developed. This system is called "InfoAbo".

With the introduction of the UID register, an enterprise's original data need only be entered once, dispensing with the need to enter it on each occasion they deal with the authorities. New registrations, head office transfers, changes of names and addresses as well as the deletion of enterprises are automatically sent via the UID InfoAbo to the relevant administrative services.

All information regarding InfoAbo-Report and InfoAbo-Configuration can be found in the document "The UID InfoAbo".

Two types of notification can be sent via InfoAbo:

  • Replies to the sender: feedback to the notifying UID service with confirmation or refusal of the new entries or changes made.
  • Notification to the services concerned: interested parties are informed of the new entries and changes made by other administrative or UID services.

All the necessary information about the InfoAbo report and the configuration of the InfoAbo are available in the document "InfoAbo operating principles" (available in German, French and Italian).
