What is the Meldebescheinigung?

The certificate of registration (Meldebescheinigung) is a document that confirms that you still live at a certain address. You can request a Meldebescheinigung from the Bürgeramt.

The Anmeldebestätigung is often called the Meldebescheinigung, but that's a different document. You only get the Anmeldebestätigung when you register your address, but you can request a Meldebescheinigung anytime. If you moved a long time ago, you might need a recent Anmeldebestätigung to prove that you still live there.
