Area Code 2458 – Soleuvre/Differdange

Geographic Coverage and Administrative Jurisdiction

The +352 2458 prefix is a geographic number range allocated within the Luxembourgish national numbering plan, specifically serving the communes of Soleuvre and Differdange in the canton of Esch-sur-Alzette, in the southwestern part of the Grand Duchy of Luxembourg. This area is part of the industrial heartland known as the 'Terres Rouges' (Red Lands), historically centered on steel production. The prefix is assigned to fixed-line services, typically provided by the incumbent operator (POST Luxembourg) or alternative carriers, and is used for both residential and business subscribers within this locality.

Dialing Formats and Caller Instructions

Luxembourg uses a closed dialing plan, meaning that the full national number (including the prefix) must always be dialed, even for local calls. The national number for a subscriber in this area is 2458 followed by the subscriber's extension number, typically 4 to 5 digits, resulting in a total national number length of 8 or 9 digits. For example, a local number might be 2458 1234 (8 digits) or 2458 12345 (9 digits).

• Local calls (within Luxembourg): Dial the full national number: 2458 1234. Do not add any trunk prefix, as none is used in Luxembourg.
• International calls from abroad: Dial the international access prefix (00 or +), then the Luxembourg country code 352, followed by the national number without any leading zero: +352 2458 1234.
• Calls from a mobile phone in Luxembourg: Simply dial 2458 1234, as the network automatically recognizes the geographic destination.

Overlay and Numbering Considerations

Luxembourg does not use area codes in the traditional sense; instead, the entire country is treated as a single numbering area. The prefix 2458 is part of a broader range (245x) that serves the Differdange/Soleuvre region. There are no overlay codes or changes required for local dialing. Number portability is available, allowing subscribers to retain their numbers when changing operators, but the geographic significance of the prefix may be lost if the number is ported to a non-geographic service.

Practical Usage

Businesses and residents in Soleuvre and Differdange use this prefix for fixed-line telephony, including fax and DSL services. Callers from outside Luxembourg should note that the country code +352 is mandatory, and the national number must be dialed in full. For example, a caller from France would dial: 00 352 2458 1234. For callers within Luxembourg, the number is dialed exactly as it appears in the local directory.
