Permits and registration
Register your Finnish address at the Digital and Population Data Services Agency (DVV) within 7 days of arriving.
Your official registration unlocks almost everything else - your henkilötunnus, banking, healthcare access, and Kela benefits.
Visit your local DVV office (maistraatti) or register online at dvv.fi. You will need a valid passport or ID, your rental agreement or a confirmation of your accommodation, and your residence permit if you are from outside the EU/EEA. The process is free and usually takes 15–30 minutes in person.
