Regulatory and Technical Notes
As a geographic code, 02366 is administered by the German Federal Network Agency (Bundesnetzagentur). The code is not portable outside the geographic area, meaning that a number assigned to this NDC is tied to the Herten exchange area. However, within the area, number portability is possible between different providers. The code is used for both fixed-line PSTN and VoIP services, but the geographic location remains the basis for tariffing and emergency services routing.
Herten is not subject to any overlay codes, so the 02366 code is the sole area code for the region. Callers within the same code area can often dial the subscriber number without the area code, depending on their local exchange configuration, but for clarity and reliability, it is recommended to always use the full national or international format.
