FAQ
Which city should I use for federal ministries?
Use "Berlin" for most federal ministries as they have moved to Berlin. Some ministries like BMF (Finance) still have major operations in Bonn - check the specific address.
How do I handle cities that are also federal states?
Use the city name: "Berlin", "Hamburg", "Bremen". The federal state context is understood from the organization name and address.
Should I include district information for large cities?
Generally use the main city name unless the district has its own postal identity. For Berlin, use "Berlin" rather than specific districts like "Berlin-Mitte".
