Area Code 2654 – Esch-sur-Alzette

Geographic Overview

The +352 2654 prefix is a geographic number range assigned to the Esch-sur-Alzette area in the Grand Duchy of Luxembourg. Esch-sur-Alzette, located in the southern part of the country near the French border, is the second-largest city in Luxembourg and serves as the capital of the canton of Esch-sur-Alzette. This numbering range is part of the national numbering plan administered by the Institut Luxembourgeois de Régulation (ILR), in accordance with ITU-T E.164 recommendations.

Dialing Formats

When calling a number using the 2654 prefix from within Luxembourg, subscribers typically dial the eight-digit national significant number (NSN) without any trunk prefix. For example, a local call to a subscriber would be placed as 2654 1234 (or the full eight-digit number as assigned). From abroad, callers must dial the international access code (00 or +), followed by Luxembourg's country code +352, and then the eight-digit subscriber number. Thus, an international call would be formatted as +352 2654 1234.

Geographic Coverage and Administrative Jurisdiction

The 2654 prefix is allocated to the Esch-sur-Alzette exchange area, which encompasses the city proper and its surrounding communes. This includes the administrative jurisdiction of the Esch-sur-Alzette canton, which is part of the electoral district of Sud. The area is a significant economic hub, home to the University of Luxembourg's Belval campus and the former steel industry sites now developed into a modern science and technology park. The prefix serves both residential and business customers within this region.

Numbering Plan Considerations

Luxembourg employs a closed numbering plan, meaning that all subscriber numbers, whether geographic or mobile, are eight digits long. Geographic prefixes, such as 2654, are not used as overlay codes; instead, each geographic area has its own distinct prefix range. This simplifies dialing: no trunk prefix or area code is required for domestic calls. For callers within Luxembourg, dialing the eight-digit number is sufficient. For international callers, the country code +352 is added before the eight-digit number.

It is important to note that number portability is available in Luxembourg. A subscriber may retain their 2654 number when moving to a different geographic area, but the number will remain associated with the original exchange. However, for new allocations, the prefix indicates the geographic location of the line. Businesses and residents in Esch-sur-Alzette should ensure that their contact details reflect the correct international format to avoid dialing errors.
