Geographic Coverage and Administrative Jurisdiction
The area code +49 261 is a geographic National Destination Code (NDC) assigned to the city of Koblenz and its immediate surrounding areas in the state of Rhineland-Palatinate (Rheinland-Pfalz), Germany. Koblenz, situated at the confluence of the Rhine and Moselle rivers, serves as the administrative seat of the district of Mayen-Koblenz and is one of the oldest cities in Germany. The code covers the urban core of Koblenz, including districts such as Altstadt, Mitte, Süd, and parts of the neighboring municipalities like Lahnstein and Vallendar, which are within the city's metropolitan influence.
Dialing Formats and Number Structure
Within Germany, local calls to Koblenz numbers are made using the 0 261 prefix followed by the subscriber number, which typically has a length of 5 to 7 digits. The complete national significant number (NSN) is therefore 10 to 11 digits including the leading trunk prefix '0'. For example, a local number might be dialed as 0261 123456.
From abroad, callers must use the international format: the German country code +49, followed by the area code 261 (without the leading '0'), and then the subscriber number. For instance, a call from the United States to the same number would be dialed as +49 261 123456. It is important to note that the trunk prefix '0' is only used within Germany and must be omitted when dialing from outside the country.
Overlay and Numbering Considerations
As of the latest ITU-T E.164 national numbering plan updates, the 261 area code does not have an overlay code. Subscribers in Koblenz have a single geographic area code, and local calls are charged at standard fixed-line rates. The code is administered by the German Federal Network Agency (Bundesnetzagentur) and is allocated to various fixed-line operators, including Deutsche Telekom, Vodafone, and regional carriers, enabling number portability across providers.
Caller Instructions
- Local callers within Koblenz can dial the subscriber number directly without the area code, but it is common practice to include the area code for clarity.
