Area Code 2137 – Neuss-Norf

Overview of Area Code 2137 (Neuss-Norf)

Area code 2137 is a geographic destination code within the German national numbering plan, conforming to ITU-T E.164 recommendations. It is assigned to the district of Neuss-Norf, located in the western part of the city of Neuss, in the federal state of North Rhine-Westphalia. The code serves the local exchange area that encompasses the districts of Norf, Rosellen, and parts of the surrounding communities, including the localities of Hoisten and Grefrath. Administratively, these areas fall under the jurisdiction of the Rhein-Kreis Neuss district, and the code is managed by the German Federal Network Agency (Bundesnetzagentur).

Geographic Coverage and Dialing Formats

The area code 2137 is used for fixed-line telephone services within the Neuss-Norf area. When dialing locally within the same code, callers can typically use the abbreviated format, omitting the area code. However, for calls originating from other regions within Germany, the full national trunk prefix 0 must be dialed, followed by the area code and the subscriber number. The international format for callers from abroad requires the German country code +49, followed by the area code without the leading zero, and then the subscriber number.

For example, a local call to a subscriber number 123456 within the Neuss-Norf area would be dialed as 123456. A call from elsewhere in Germany would be dialed as 02137 123456. An international caller would dial +49 2137 123456.

Overlay and Numbering Considerations

Currently, there is no overlay code for the 2137 area, meaning that the area code is unique to this region. The subscriber numbers within this code typically have a length of 6 to 7 digits, resulting in a total national significant number length of 10 or 11 digits, including the area code. This is consistent with the German numbering plan, which allows for variable subscriber number lengths.

Caller Instructions

For local callers within the 2137 area, it is important to note that even local calls may require the area code if the call is made between different local exchanges that share the same code. To avoid confusion, it is recommended to always use the full national format (0 2137) when dialing from a mobile phone or from a fixed line outside the immediate local area. For foreign callers, it is essential to replace the leading zero with the +49 country code, and to ensure that the correct international exit code is used when dialing from their country.

As with all geographic numbers in Germany, calls to 2137 numbers are typically charged at standard landline rates, depending on the caller's tariff. Mobile and VoIP users should check their specific rate plans for any variations.
