Where must you register if you move in Germany?

1. at the residents' registration office (Einwohnermeldeamt) ✓
2. at the registry office (Standesamt)
3. at the public order office (Ordnungsamt)
4. at the trade office (Gewerbeamt)

Registering your address at the Einwohnermeldeamt is a legal requirement that helps you access health insurance and other essential services. It's the official way of saying 'I live here now!'
