By the end of 2025 people may only have a permanent address in one country - 12,000 persons currently have an address in both Finland and Estonia

Finland and Estonia concluded a treaty on the smoother exchange of information between their population registers in September 2022, and it entered into force on 1 May 2024. In its first phase, which began on 15 April 2025, the exchange of information concerns data on deaths. Starting in December 2025, information on moves from one country to another will also be transferred automatically. At the same time, the authorities will also investigate all earlier cases. This will ensure that the address data of people who move between Finland and Estonia will be kept up to date in the population registers of both countries.
