Area Code 2571 – Greven Westfalen

Geographic Overview and Administrative Jurisdiction

The German national destination code 02571 is a geographic area code assigned to the city of Greven in the federal state of North Rhine-Westphalia (Nordrhein-Westfalen). Greven is situated in the Münsterland region, approximately 20 kilometers northwest of Münster. The code covers the urban area of Greven, including its districts such as Reckenfeld, Schmedehausen, and Gimbte, as well as the surrounding rural communities that fall within the local exchange area. As a geographic code, 02571 is used exclusively for fixed-line telephone services (PSTN and VoIP) that are physically or administratively tied to this locality.

Dialing Formats and Caller Instructions

For callers within Germany, reaching a number in Greven requires dialing the national trunk prefix 0 followed by the area code and the local subscriber number. The local subscriber numbers in this area typically consist of 6 to 7 digits, resulting in a complete national significant number (NSN) of 10 or 11 digits when including the leading zero. For example, a local number might be formatted as 02571 123456.

International callers must replace the leading zero with the German country code +49, omitting the trunk prefix. Thus, the same number would be dialed as +49 2571 123456 from abroad. When calling from a mobile phone within Germany, it is generally acceptable to dial the number in international format (+49 2571 ...) as well, though the national format is also valid.

Overlay and Numbering Plan Considerations

Currently, there is no overlay code for the 02571 area; the region uses a single area code without additional overlays. However, as with all German geographic codes, number portability allows subscribers to retain their 02571 numbers when switching to a different fixed-line provider or even to a VoIP service, provided the service is registered to the same geographic area. This means that a number with the 02571 prefix may not necessarily be physically located in Greven if the user has ported it to a non-geographic service, but the number remains associated with the original tariff zone for billing and emergency services routing.

Practical Calling Examples

To illustrate, a local call from a landline in Greven to another local number would simply require dialing the 6- or 7-digit subscriber number without the area code. A call from elsewhere in Germany (e.g., from Berlin) would be dialed as 02571 123456. An international caller from the United States would dial 011 49 2571 123456, while a caller from the United Kingdom would dial 00 49 2571 123456. These formats ensure proper routing through the public switched telephone network (PSTN) to the intended subscriber in Greven.
