Registration of change of address in the Population Information System
If you are a Finnish citizen and live outside Finland, you must notify the Digital and Population Data Services Agency of change of your address.
It is important to keep address data up to date. Matters such as military service are based on the address and nationality data in the Population Register System. You can be notified of your right to vote or the threat of losing your citizenship only if your address details are correct in the register.
Changes of address abroad can be notified either directly to a Digital and Population Data Services Agency (Link to another website.) (Opens New Window)in Finland or to a Finnish mission.
