The Population Information System is maintained by local register offices called Maistraatti/Magistrat and keeps record of the Finnish population data. Everyone residing in Finland for periods exceeding three months is registered with this system. The information collected by the Population Information System is used for purposes like organisation of elections, employment and taxation, health care, statistical purposes, and in judicial administration. Naturally, all information is treated confidentially.
As a general rule foreign citizens, whose residence in Finland is permanent or exceeds one year, can get a personal identity code (henkilötunnus/personnummer). The personal identity code is issued by the Local Register Office (maistraatti/magistrat) and requires registration at this office. The registration has to be done personally. When registering at the Local Register Office, your information including name, date of birth, nationality, family relationships and address will be entered into the Finnish Population Information System. The personal identity code is a means of identification which is more specific than a name.
The personal identity code is needed in a variety of situations in Finnish everyday life such as payment of salaries, opening a bank accound or for paying with a debit/credit card, renting a flat, and health care.
Foreign citizens staying in Finland for less than one year can also be entered into the Population Information System, if this is necessary in order to be able to stay or work in Finland. In this case, it is possible to get a personal identity code. The Local Register Office makes the decisions concerning the issuance of personal identity codes. For the registration you will need a passport, a valid residence permit and, if applicable, a marriage certificate and birth certificates for the children.
Please note that the documents must be legalized (Apostille / Grand Legalization) and translated. An official notification of move is needed whenever your address changes, including when your residence in Finland ends.
