Registration of citizenship 

You can have several citizenships recorded in the Population Information System. We can record your citizenship in the Population Information System based on a valid passport, an original decision on naturalisation or some other reliable evidence. 

If you are a Finnish citizen, you have the obligation to notify the Finnish Population Information System of the foreign citizenship you have received.

If you are applying for Finnish citizenship, contact the Finnish Immigration Service.  

Which documents can I use to prove my citizenship?

Do the following

 

1. Fill in the form below.       

Correction/addition to register information – international 

 

2. Find out whether the document must be legalised and/or translated.

  • You must present the document either as an original or as a certified copy
    • If your document must be legalised, a copy of it must be requested of the legalised document. The copy is then also legalised.
    • A certified copy can be issued either by a notary public or by the same authority that issued the original document

 

3. Deliver the documents as follows:
A) Through the Finnish mission 

  • If you are a Finnish citizen or a foreign citizen permanently residing in Finland
  • Otherwise, you can ask the diplomatic mission whether it is possible to submit documents through them

B) By post

  • Send the form and documents 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.

C)    By bringing the documents to our service location

NOTE. Only electronic documents that can be verified can be sent by email (for example, the document was originally issued electronically by a foreign authority). If necessary, the electronic document must also be legalised. An electronic document does not mean a scanned document. 


See more detailed instructions for submitting documents.
 

4. Please note that inquiries and email messages will not speed up the processing of the notifications. We will contact you if we need more information. You will receive an extract from the Population Information System after your details have been recorded. Check that the 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.
