FAQ
Should I use the official city name or common name?
Use the official postal city name as recognized by Deutsche Post. For cities with districts, use the main city name unless the district has its own postal identity.
What about cities with special characters or umlauts?
Include German umlauts and special characters as they appear officially (ä, ö, ü, ß). Most electronic systems now support these characters properly.
How should I handle compound city names?
Use the complete official name including connecting words (e.g., "Frankfurt am Main", "Neustadt an der Weinstraße"). Don't abbreviate unless space is critically limited.
