In Germany, you must register your address at the Bürgeramt. This will become your official address in Germany. This is called the Anmeldung.
When you do your Anmeldung, you get…
- A registration certificate (Anmeldebestätigung)
- A tax ID (Steueridentifikationsnummer)
In Berlin, you can do your Abmeldung in person, or pay someone to do it for you.
