Change of name abroad 

If you change your forename or surname abroad, please notify us following the instructions on this page. We will record the name change in the Finnish Population Information System. This way your personal data will be up to date and using the services of the Finnish authorities will be easier. If you are a Finnish citizen, you have the obligation to notify the Finnish Population Information System of your name change.  

You can prove that you have changed your name abroad by means of a document showing your new name, such as a passport or a decision issued by a foreign authority. You can alternatively submit a certified copy of your passport.  

If you got married abroad and changed your surname, we can record your new name in the Population Information System. Your new surname must be shown in your marriage certificate or proof of identity document. Read more about the notification of a marriage concluded abroad and the change of name in connection with it.

3. Submit the documents either by through a Finnish mission or by sending them by post to Digital and Population Data Services Agency, PL 1003, 00531 HELSINKI, FINLAND. If your municipality of residence was in Åland before moving abroad, send the documents to Statens ämbetsverk på Åland.

  • if necessary, the original or a certified copy of the translation of the document, legalised if required. 

4. Inquiries and email messages will not speed up the processing of notifications. We will contact you if we need further information. You will receive a confirmation from us once your new name has been recorded. Check that your information has been entered correctly. If for some reason we do not record the information you have submitted in the Population Information System, you will receive a decision on this. Instructions for submitting a request for administrative review are attached to the decision.   

N. B.! Cases are processed in their order of arrival. Unfortunately, we cannot speed up an individual case unless there is a very exceptional and very important reason for doing so. For example, opening a bank account is not a sufficient justification for speeding up the process.


Free of charge.

When the registration has been completed, we will inform you about it by posting an extract from the Population Information System to you.
