📍 Geographic Location of Waltrop
Overview of Area Code 2309 (Waltrop)
Area code 2309 is a geographic National Destination Code (NDC) within the German telephone numbering plan, assigned to the town of Waltrop and its immediate surroundings. Waltrop is located in the northern part of the Ruhr metropolitan region, within the state of North Rhine-Westphalia (Nordrhein-Westfalen). The code serves the local exchange area of Waltrop, which is administratively part of the Kreis Recklinghausen district. The area is bordered by the cities of Datteln, Castrop-Rauxel, and Lünen, but those localities use their own distinct area codes (e.g., 2363 for Datteln, 2305 for Castrop-Rauxel, 2306 for Lünen).
Geographically, the 2309 code covers the entire municipal territory of Waltrop, including its central town and the districts of Brockenscheidt, Oberwiese, and Leveringhausen. The population of Waltrop is approximately 29,000, and the area is characterized by a mix of residential neighborhoods, commercial zones, and remnants of the region's industrial heritage, such as the former Zeche Waltrop mine. The code is used for fixed-line telephone services, including PSTN and VoIP connections, provided by Deutsche Telekom and alternative carriers.
Dialing Formats and Usage
When dialing a number within the Waltrop area, the local format is 02309 XXXXXX, where the leading zero is the national trunk prefix. For international callers, the number must be dialed as +49 2309 XXXXXX, omitting the leading zero. The subscriber number length typically ranges from 6 to 7 digits, resulting in a total length of 10 or 11 digits when including the area code (without the trunk prefix). For example, a typical local number might be 02309 123456 or, internationally, +49 2309 123456.
Callers from within Germany but outside the 2309 area must dial the full national format: 02309 XXXXXX. Callers from abroad should use the international format: +49 2309 XXXXXX (or 0049 2309 XXXXXX when using the international prefix from many countries). It is important to note that Germany has implemented number portability, so a fixed-line number with the 2309 prefix may be assigned to a subscriber who has moved outside the geographic area, but the number retains its original area code. Conversely, a subscriber within Waltrop may have a number with a different area code if they ported their number from another location.
There are no overlay codes in this area; the 2309 code is the sole geographic code for Waltrop. The local tariff for calls to 2309 numbers depends on the caller's own fixed-line or mobile plan, but calls within the German fixed network are typically charged at standard national rates unless the plan includes flat-rate options. Emergency services (112) and other short codes are accessible without the area code.
