Area Code 2454 – Esch-sur-Alzette

Overview of Area Code 2454

Area code 2454 is a geographic National Destination Code (NDC) assigned to the city of Esch-sur-Alzette, the second-largest city in Luxembourg. This code is part of the national numbering plan administered by the Institut Luxembourgeois de Régulation (ILR) under the ITU-T E.164 framework. Esch-sur-Alzette is the administrative center of the canton of Esch-sur-Alzette and lies in the southern Red Lands region, near the French border. The code 2454 serves both residential and business subscribers within the city and its immediate suburban areas.

Geographic Coverage and Administration

The 2454 prefix covers the urban area of Esch-sur-Alzette, including neighborhoods such as Lallange, Brill, and Raemerich, as well as parts of the neighboring communes of Sanem and Schifflange. As a geographic code, it is tied to a physical exchange area, and subscribers are typically connected via fixed-line PSTN or VoIP services that are registered to an address within the coverage zone. The code is administered by the ILR, which ensures that number allocation remains consistent with the national telecommunication regulations.

Dialing Formats and Usage

For local callers within Luxembourg, the national format is 2454 12345 (without the leading '0', as Luxembourg does not use trunk prefixes). For international callers, the full international format is +352 2454 12345. When calling from abroad, you must replace the '+' with your country's international access code (e.g., '011' from the US, '00' from most European countries). The number length after the country code is 9 digits, which includes the NDC (2454) and the subscriber number (5 to 6 digits).

Overlay and Numbering Considerations

Luxembourg has a closed numbering plan, meaning that all numbers, including those in Esch-sur-Alzette, are dialed in full national format even for local calls. There are no overlay codes in Luxembourg; each geographic area has a unique NDC. However, number portability is available, so a subscriber may retain a 2454 number even if they move to another part of the country, though the number remains associated with the original geographic area for routing purposes.

Caller Instructions

For local callers: simply dial the 9-digit national number, e.g., 2454 12345. For international callers: dial your country's exit code, then 352, then the 9-digit number, e.g., +352 2454 12345. Ensure you drop any leading '0' if you are accustomed to using trunk prefixes in other countries; Luxembourg does not use them.
