Jurisdictional and Administrative Notes

This geographic allocation follows the German numbering plan administered by the Federal Network Agency (Bundesnetzagentur).
Overlay and Number Portability
Currently, there is no overlay code for 02357, meaning that local calls within the same area code do not require an additional area code. However, due to number portability, a number with the 02357 prefix may be assigned to a subscriber who has moved to a different region, but the original geographic code remains. This is an important consideration when identifying the physical location of a caller.
Caller Instructions
For callers within Germany, always dial 02357 followed by the subscriber number, even if you are calling from within the same area code (though local calls may be dialed without the area code in some legacy systems, it is safer to include it). For international callers, dial the international access prefix (e.g., 00 from most European countries, 011 from the US/Canada), then 49, then 2357, and finally the subscriber number, omitting the leading zero.
