Stranger at my address — Digi- ja väestötietovirasto (DVV)

Direct answer

It happens more than you would think: a previous tenant who never deregistered, or a fraudster using your address. It can affect your benefits, taxes and mail, so act. Ask Digi- ja väestötietovirasto (DVV) (0295 536 000) — the population registry — to start an address investigation: you declare that the person does not live there, they check, and the entry is corrected or moved to "unknown". Kunta — asiakaspalvelu / ympäristövalvonta (kuntaliitto.fi) is the desk for it in many municipalities. If mail arrives suggesting fraud (loans, orders, court letters in their name), Poliisi — rikosilmoitus (poliisi.fi) takes the report.

❓ Frequently asked

Does it affect my benefits?

It can — a "household" of two changes calculations. Tell the benefit agency in writing that the person does not live there and that an investigation is running.

A former flatmate will not deregister

The same investigation route. Their new address is their problem; the register can set them to "departed, unknown".

Someone used my address for a company

Report to the company register as well; a registered office at your home without consent can be removed.
