📍 Geographic Location of Würselen
Geographic Overview
The +49 2405 area code is a geographic National Destination Code (NDC) assigned to the city of Würselen, located in the western part of North Rhine-Westphalia, Germany. Würselen lies directly adjacent to the city of Aachen and forms part of the Aachen urban region (Städteregion Aachen). The code covers the entire municipal area of Würselen, including its districts such as Broichweiden, Linden-Neusen, Morsbach, and the town center. As a geographic code, it is tied to the PSTN (Public Switched Telephone Network) infrastructure, although calls may be carried over IP-based networks by modern carriers.
Dialing Formats
For callers within Germany, the area code is dialed with a leading zero: 02405. The complete national subscriber number (NSN) typically consists of the area code plus a local subscriber number, resulting in a total length of 10 to 11 digits (excluding the international prefix). For example, a local number might be 02405 123456.
For international callers, the German country code +49 is used, and the leading zero of the area code is dropped. Thus, the same number is dialed as +49 2405 123456 from abroad. When calling from a mobile phone within Germany, it is generally necessary to include the area code even for local calls, as mobile networks do not recognize local dialing without the full NDC.
Geographic Coverage and Neighboring Codes
Würselen is bordered by Aachen (area code 0241) to the south, Herzogenrath (02406) to the west, and Alsdorf (02404) to the north. The area code 02405 is exclusively used for Würselen and does not cover any other major municipalities. The proximity to Aachen means that calls between Würselen and Aachen are charged as local or regional calls, depending on the tariff plan of the caller's provider.
Numbering and Overlay Considerations
Germany's numbering plan is administered by the Federal Network Agency (Bundesnetzagentur). The 02405 area code has not been overlaid with another code, meaning that all numbers within this area share the same geographic prefix. Subscriber numbers can vary in length, but the total length of the national significant number (NSN) is standardized to 11 digits (including the leading zero of the area code). This allows for a maximum of 10 million numbers, though actual allocation is far lower.
Caller Instructions
For local callers within Würselen: When dialing another local number, it is still necessary to dial the full area code (02405) followed by the subscriber number, as German fixed-line networks do not support seven-digit local dialing in most regions. For callers from other parts of Germany, simply dial 02405 followed by the subscriber number. For callers from outside Germany, use the international format +49 2405 followed by the subscriber number, omitting the leading zero.
Emergency services (112 and 110) are reached without any area code. Directory assistance and other special services may have their own access numbers.
