Area Code 241 – Luxembourg

Overview of Luxembourg Area Code 241

Area code 241 is a geographic National Destination Code (NDC) within the Luxembourgish public switched telephone network (PSTN), allocated under the country calling code +352. It serves the central and northern parts of the Grand Duchy, primarily covering the capital city, Luxembourg City, and its surrounding communes. As a fully integrated numbering plan, Luxembourg does not use trunk prefixes; therefore, callers within the country dial the eight-digit subscriber number directly, starting with the area code. For international callers, the number is formatted as +352 241 xxx xx (or +352241xxxxx when dialed without spaces).

Geographic Coverage and Administrative Jurisdiction

The 241 prefix is assigned to fixed-line services within the Canton of Luxembourg, which includes the capital and key administrative districts such as Kirchberg, Limpertsberg, and Bonnevoie. It also extends to nearby towns like Strassen, Bertrange, and Mamer, which function as suburban hubs for businesses and government institutions. This area is the economic and political heart of the country, hosting the European Union institutions, the Luxembourg Stock Exchange, and numerous multinational headquarters.

Dialing Formats and Caller Instructions

• Local callers (within Luxembourg): Dial the full eight-digit number, e.g., 241 123 45. No trunk prefix (like '0') is used.
• International callers: Dial the international access prefix (00 or +), followed by the country code 352 and the eight-digit number, e.g., +352 241 123 45.
• Callers from countries with different exit codes: Replace the '+' with the appropriate international prefix (e.g., 011 from North America).

Overlay and Numbering Considerations

Luxembourg employs a closed numbering plan with no area code overlays. The 241 prefix is not overlaid by other geographic codes; instead, the country uses distinct NDCs for different regions (e.g., 26 for the south, 27 for the north). Number portability allows subscribers to retain their 241 number when moving within the country, but the geographic association remains for routing purposes. For VoIP users, the 241 prefix can be assigned to nomadic services, but it still indicates a Luxembourg-based number.

Practical Examples

To illustrate, a business in Luxembourg City might have the number +352 241 555 00. A local caller would dial 241 555 00, while a caller from France would dial 00 352 241 555 00. For international SMS or fax, the same formatting applies. Always verify the number length (eight digits) when dialing, as omitting a digit will result in a failed call.
