Polish citizens can book a slot online to register a permanent address, or a temporary stay of over three months.
Bring the completed signed form, ID, accepted mObywatel identity document or passport, and evidence of the legal right to occupy the property. The owner or another authorised holder confirms your actual stay; if you hold the legal right yourself, you confirm it. Online filing requires the relevant electronic housing-right documents and, where needed, the owner’s confirmation or their digital copies.
