Notify the address or name change of the main unit of a company or organisation in the Business Information System (YTJ)
If the address or the name of the company’s main unit changes, submit a notification to the Business Information System based on electronic identification. The new address or name will then also be updated to the Transport Register.
Do the same if you want to enter the company’s PO Box or Poste Restante address in the Transport Register. In this case, the company cannot have another address in the Population Information System.
