Area Code 2352 – Altena Westfalen

Geographic Overview

The area code +49 2352 is a geographic National Destination Code (NDC) assigned to the region of Altena in Westphalia (Altena Westfalen), located in the state of North Rhine-Westphalia, Germany. This code serves the city of Altena and its surrounding municipalities, including parts of the Märkischer Kreis district. The service area encompasses both the urban center of Altena and nearby communities such as Nachrodt-Wiblingwerde and portions of the Lenne valley. As a geographic code, it is tied to the physical PSTN infrastructure of the region, although calls may be routed over IP-based networks by modern carriers.

Dialing Formats

When calling a subscriber within Germany, the national trunk prefix 0 must be dialed before the area code. Thus, a local number is reached by dialing 02352 [subscriber number]. For international callers, the German country code +49 replaces the leading zero, resulting in the format +49 2352 [subscriber number]. For example, a typical landline number in Altena might be +49 2352 123456 (or 02352 123456 domestically). Subscriber numbers in this area typically have between 4 and 7 digits, depending on the specific exchange and historical allocation.

Caller Instructions

• Local callers (within Altena): If you are dialing from another number within the same area code, you may often omit the area code and dial only the subscriber number, depending on your carrier's local dialing rules. However, for clarity and to avoid misdialing, it is recommended to always include the area code.
• National callers (from elsewhere in Germany): Dial 02352 followed by the subscriber number. Do not use the +49 international prefix when dialing from within Germany.
• International callers (from outside Germany): Dial the international access prefix (e.g., 00 from most European countries, or 011 from the US/Canada), then 49, then 2352, and finally the subscriber number. Drop the leading zero of the area code.

Overlay and Numbering Considerations

As of the latest ITU-T and German Federal Network Agency (Bundesnetzagentur) data, there is no overlay code for the 2352 area. The numbering capacity is sufficient for the region's demand, and no changes are currently planned. However, with the ongoing migration to all-IP telephony, some subscribers may have numbers that are not tied to a physical location, but the geographic significance remains for routing and emergency services.

Practical Usage

Businesses and residents in Altena use this code for landline services, and it is also used for some VoIP services that offer geographic numbers. When dialing from abroad, ensure you have the correct subscriber number, as omitting digits can lead to misrouting. For emergency services (112 or 110), the area code is not required; these numbers are valid throughout Germany and the EU.
