Area Code 2388 – Hamm-Uentrop

Geographic Coverage and Administrative Jurisdiction

The area code 02388 (international format +49 2388) is a geographic destination code assigned to the Hamm-Uentrop area within the city of Hamm, located in the state of North Rhine-Westphalia, Germany. This code specifically serves the eastern districts of Hamm, including Uentrop, and may extend to adjacent localities such as Werries and Braam-Ostwennemar. As a geographic number, it is tied to the PSTN infrastructure of this region, and calls to numbers bearing this prefix are routed to fixed-line subscribers within this defined area.

Dialing Formats and Caller Instructions

For domestic callers within Germany, the local dialing format is 02388 XXXXXX, where the leading zero is part of the national trunk prefix. When dialing from abroad, the international format must be used: +49 2388 XXXXXX. The subscriber number length typically ranges from 6 to 7 digits, resulting in a complete national significant number (NSN) of 10 or 11 digits when including the area code (excluding the trunk prefix). For example, a local number might be 02388 123456, which becomes +49 2388 123456 for international callers.

Callers from within Germany should note that the leading zero is required for all domestic calls, including those made from mobile phones. International callers must replace the leading zero with the German country code +49. No additional access codes are needed when dialing from most countries, but if you are in a country using international prefix (e.g., 011 in the US), dial 011 49 2388 followed by the local number.

Overlay and Numbering Plan Considerations

As of the current ITU-T E.164 allocation for Germany, the 02388 area code does not have an overlay code. The city of Hamm is primarily served by the 02381 code for central areas, while 02388 is dedicated to the Uentrop district. This separation ensures that local calls within the same geographic region may require the full area code if dialing between different districts. For example, a caller in central Hamm (02381) must dial 02388 followed by the subscriber number to reach a party in Uentrop, even though both are within the same city. This is standard practice in Germany's open dialing plan, where area codes are mandatory for calls between different numbering areas.

Service and Usage Notes

Numbers under 02388 are primarily used for fixed-line telephony, including residential and business services. They are also used for ISDN and VoIP lines that are registered to physical addresses within the coverage area. However, due to number portability, a number with this prefix may be reassigned to a user located elsewhere, but the geographic association remains for routing purposes. For emergency services, dialing 112 (EU-wide) or 110 (police) works regardless of the area code. For international callers, be aware that calls to German fixed-line numbers are typically charged at varying rates depending on your carrier, but there are no special premium charges associated with this standard geographic code.
