Change your register details

It is very important that you notify the PRH immediately if your name, company type, address or other such details change.

It is in your own interest to keep the register details up to date, as we rely on the register for example when we remind trademark owners of due renewals at least 6 months before their registrations expire.

Check your current details in our Trademark Database.

How to apply

Use our online service for registered trademarks (available in Finnish and in Swedish) to submit the changes. The service requires user identification through the portal. Go to the service.

We can accept applications filed on paper or by email only for special reasons, for example if the online service is unavailable due to a technical problem or an interruption to the data traffic, or if the applicant has no real chance of using the online service.


In most cases, we charge a fee for changing the register details. Note that if you are paying for the application from abroad you must also pay any handling fees charged by your bank.See the fees on our price list and payment instructions.
