Anyone who moves to or within Germany should register their name and residential address at the Residents’ Registration Office ("Einwohnermeldeamt", "Bürgeramt" or "Bürgerbüro") within two weeks at the latest. If you don't register or do it too late, you might have to pay a fine. When you register you will receive an Official Registration Confirmation ("Amtliche Meldebestätigung"). Keep this paper in a safe place. This enables you to prove - even without your ID - that you are registered in a municipality or city in Germany, i.e. you reside there.
Registering your address in Germany
Where and when to do the "Anmeldung"?

In principle, all those who come to Germany and want to stay longer than three months, have to register ("Anmeldung") their residential address with the German authorities after two weeksat the latest. Even if you move within Germany, you must always inform the authorities about your new address.
Important: This registration has nothing to do with the registration you -as an asylum seeker- need to do at the immigration office, i.e. refugees are required to do both. Find out more about registeration process for refugees in the chapter “Registration as an asylum seeker”. Details of registration laws are specified in the Federal Registration Act (BMG).
What do I need to know?
Important
If you are being stalked or working in a profession in which you are potentially at risk, you can apply to block your personal data at your local Residents' Registration Office by §51 of the Federal Registration Law ("Bundesmeldegesetz"). Your address is then hidden and cannot be queried by a third party.
