When calling a Datteln number from within Germany, you must use the national trunk prefix 0 followed by the area code and the subscriber's local number. For example, a local Datteln number might be dialed as 02363 456789. From abroad, you would dial the international access code (e.g., 00 from most countries), then Germany's country code +49, followed by the area code without the leading zero, and the subscriber number: +49 2363 456789.
Number Structure and Overlays
Subscriber numbers in the 02363 area typically have between 5 and 7 digits, depending on the historical allocation. The total length of a national significant number (NSN) for a Datteln fixed-line number is usually 10 or 11 digits, including the area code but excluding the trunk prefix. There are no overlay codes in this region; the 02363 code is exclusive to Datteln. However, due to number portability, a number with this prefix may have been moved to a different provider or even a different technology (e.g., VoIP), but the geographic association remains for administrative purposes.
Caller Instructions
For local callers within Datteln, it is possible to dial the subscriber number without the area code if the call is within the same local network, but this practice is becoming less common. For all other domestic calls, the full national format with the leading 0 is required. International callers should always drop the leading 0 and use the +49 country code. When storing numbers in a mobile phone, it is recommended to use the international format (+49 2363 ...) to ensure proper routing both domestically and abroad.
Regulatory and Technical Notes
The allocation of geographic numbers in Germany is regulated by the Federal Network Agency (Bundesnetzagentur).

However, with the rise of flat-rate calling plans and VoIP, the actual cost may vary. Emergency services and directory assistance are reached via short codes and are not affected by this area code.
