For each election, the Population Register Centre establishes a register of eligible voters (a voting register) based on the Population Information System. In this context, it also posts the notification of eligibility (notification card) to each eligible voter.
The Population Information System is also used to check the details of candidates and to establish the register of candidates.
When there is an election in Finland, the Population Register Centre provides a Polling Station Service on this website. The service can be used to check the location of the nearest advance polling station and the polling station on the actual election day on the map. Unfortunately, this service is only available in Finnish.
