Caller Instructions
For local callers within Lünen, it is often possible to dial just the subscriber number without the area code, depending on the local exchange configuration. However, for clarity and to avoid misdialing, it is recommended to always use the full national format. For callers from other German regions, dial 02306 followed by the subscriber number. For international callers, dial the international access prefix (e.g., 00 from most countries) followed by 49, then 2306, and the subscriber number. Remember to omit the leading zero of the area code when dialing from abroad.
Overlay and Regulatory Notes
As of the latest numbering plan updates, there is no overlay code for the Lünen area; the 02306 code is exclusively used for the geographic area. The Federal Network Agency (Bundesnetzagentur) manages the allocation of numbers, and all fixed-line numbers in this area are portable among service providers. This means that a subscriber may retain their 02306 number even if they switch to a different carrier, including VoIP providers. However, the number remains associated with the geographic location for routing purposes, and emergency services (112) use location data to dispatch help.
