FAQ
How should I format addresses for German public authorities?
Use the complete official address as listed in public directories. For ministries, include the full street address, not just "Wilhelmstraße 97" but the complete official location.
Should I use the department address or main organization address?
Use the address where invoices should be sent for processing and payment. This might be different from the main organization address, especially for large public institutions.
What about PO Boxes for public institutions?
Many German public institutions use PO Boxes for invoice processing. Format as "Postfach [number]" (e.g., "Postfach 123456"). Check with the institution for their preferred invoice delivery address.
