Area Code 2505 – Altenberge Westfalen

Geographic Overview

The area code 02505 is a geographic destination code assigned to the town of Altenberge in the federal state of North Rhine-Westphalia (Nordrhein-Westfalen), Germany. Altenberge is located in the Münsterland region, approximately 15 kilometers north of the city of Münster. The code serves the municipal area of Altenberge, including its districts such as Altenberge-Dorf, Altenberge-Walddorf, and the surrounding rural settlements. As a geographic number, 02505 is administered by the German Federal Network Agency (Bundesnetzagentur) and is allocated to the local fixed-line network operated by Deutsche Telekom and other licensed carriers.

Dialing Formats

When calling a subscriber within the German fixed-line network, the national trunk prefix 0 must be dialed before the area code. For example, a local call from another German city would be dialed as 02505 123456. From abroad, callers must use the international access prefix (typically 00 or +), followed by Germany's country code 49, and then the area code without the leading zero: +49 2505 123456. Within the local calling area, it is often possible to dial only the subscriber number (e.g., 123456) without the area code, depending on the specific network configuration and carrier.

Geographic Significance and Numbering

The prefix 02505 is part of the German numbering plan that follows the ITU-T E.164 recommendation. Geographic area codes in Germany are assigned based on administrative boundaries, and each code corresponds to a specific exchange area. The number length for local subscribers typically ranges from 3 to 7 digits, resulting in a total national significant number (NSN) length of 10 to 11 digits when including the area code. For international calls, the NSN length remains the same, but the leading zero is dropped.

Overlay and Number Portability

Currently, there is no overlay code for 02505; the area code is exclusively used for Altenberge. However, number portability allows subscribers to retain their 02505 numbers when switching to a different fixed-line provider, even if the service is delivered via VoIP or other technologies. This means that the geographic association is not strictly tied to the physical location of the line, but the code remains indicative of the original geographic area.

Caller Instructions

For callers within Germany, simply dial 02505 followed by the subscriber number. For international callers, dial +49 2505 followed by the subscriber number, omitting the leading zero. It is important to note that calls to geographic numbers are typically charged at standard landline rates, which may vary depending on the caller's provider and tariff.
