Area Code 2547 – Rosendahl-Osterwick

Geographic Overview

The German area code 02547 is a geographic National Destination Code (NDC) assigned to the town of Rosendahl-Osterwick in the federal state of North Rhine-Westphalia. This code serves the Osterwick district of the municipality of Rosendahl, which is situated in the western part of the Münsterland region, near the border with the Netherlands. The area is characterized by its rural landscape, historic churches, and proximity to the larger cities of Münster and Enschede.

Dialing Formats

When calling a landline number in Rosendahl-Osterwick from within Germany, subscribers must dial the national trunk prefix 0 followed by the area code and the local subscriber number. For example, a local number might be dialed as 02547 123456. The local subscriber numbers in this area typically consist of 6 to 7 digits, making the total national number length 10 or 11 digits (excluding the leading 0).

For international callers, the German country code +49 replaces the leading zero. Thus, the same number would be dialed as +49 2547 123456 from outside Germany. It is important to omit the leading zero of the area code when dialing from abroad.

Geographic Coverage and Administration

The 02547 area code is administered by the German Federal Network Agency (Bundesnetzagentur) and is allocated exclusively to the geographic region of Rosendahl-Osterwick. This allocation is part of the national numbering plan, which ensures that geographic codes correspond to specific administrative districts. The code covers the Osterwick locality, which is one of the two main constituent communities of Rosendahl (the other being Darfeld, which has its own code, 02547 is specifically for Osterwick).

Overlay and Numbering Considerations

Currently, there is no overlay code for this area, meaning that 02547 is the sole area code for Osterwick. However, as with all German geographic codes, number portability allows subscribers to retain their numbers when changing providers, even if they move within the same geographic area. This does not affect the dialing format.

Caller Instructions

For local callers within the 02547 area, it is possible to dial the subscriber number without the area code in some cases, but for clarity and to avoid misdialing, it is recommended to always use the full national format. For callers from other parts of Germany, dial 02547 followed by the local number. For international callers, use +49 2547 followed by the local number. Ensure that you have the correct country code and omit the leading zero.
