Finnish citizens residing abroad have a statutory obligation to inform any changes in their personal data while abroad. This applies also to Finns with a dual citizenship living in Sweden.*)
You are advised to check from time to time that you address and other data in the Finnish Population Information System are up-to-date.
To check your data you can access the free service maintained by the Population Register Centre or ask the data to be checked in a local register office (https://verkkopalvelu.vrk.fi/Omat/Etusivu.aspx).
Documents concerning changed information can be either sent directly to the local register office or left to be taken there at a Finnish diplomatic mission abroad.
NB! The documents must be original copies, legalised and translated into Finnish.
Please consult the website of the Local Register Offices at http://www.maistraatti.fi/fi/Palvelut/ohjeita_ulkosuomalaisille/ where expatriate Finns are advised on how to submit information on a change in personal details. The forms are available on their websites and at www.suomi.fi.
When data in the Population Information System are up-to-date
*) Finland and Sweden have concluded a separate agreement according to which the Swedish authorities will automatically convey any changes in the personal data of Finnish citizens to the Finnish authorities. However, persons with a dual citizenship are considered to be Swedish citizens and they are therefore liable to inform changes in their data to the Finnish Population Information System themselves.
