Area Code 249 – Luxembourg

Overview of Luxembourg Area Code 249

Area code 249 is a geographic National Destination Code (NDC) within the Luxembourgish public switched telephone network (PSTN), allocated under the international country calling code +352. In accordance with ITU-T E.164 recommendations, Luxembourg employs a closed dialing plan, meaning that the national significant number (NSN) is always 9 digits long, including the leading '2' of the NDC. The code 249 serves the northern part of the country, specifically the region around the town of Wiltz and its surrounding communes, including Kautenbach, Goesdorf, and Boulaide. This area is characterized by the Ardennes hills and is part of the Diekirch district.

Geographic Coverage and Administrative Jurisdiction

The 249 prefix covers the canton of Wiltz, one of the twelve administrative cantons of Luxembourg. The principal city is Wiltz, which is also the capital of the canton. Other notable localities served by this code include Winseler, Esch-sur-Sûre, and Lac de la Haute-Sûre. The region is predominantly residential and touristic, with a mix of small businesses and public services. The code is assigned to fixed-line services, and numbers under this prefix are typically used for landlines, though some may be used for VoIP services that are registered to a physical address in the area.

Dialing Formats and Instructions

Because Luxembourg uses a closed numbering plan, the national significant number (NSN) for a subscriber in the 249 area is always 9 digits, starting with '249'. For example, a local number might be 249 123 456. To call this number from within Luxembourg, you simply dial the 9-digit number without any trunk prefix. There is no '0' to be dropped, as is common in many other countries. For international callers, the format is +352 249 123 456 (or 00352 249 123 456 from countries using the international prefix 00). When calling from a mobile phone, the plus sign (+) is often used to denote the international access code, so you would dial +352 249 123 456. It is important to note that there are no area code overlays in Luxembourg; each geographic region has its own distinct NDC, and the 249 code is unique to the Wiltz area.

Caller Instructions

For local callers within Luxembourg, dialing a number in the 249 area requires no special prefix—just the full 9-digit number. For example, if you are in Luxembourg City and wish to call a business in Wiltz, you would dial 249 123 456. For international callers, you must include the country code +352 and then the 9-digit number, omitting any leading zero (though there is none). It is also worth noting that Luxembourg has implemented number portability, so a number with the 249 prefix could theoretically be ported to a different geographic location or even to a mobile network, but in practice, geographic numbers are usually tied to the area. When dialing from abroad, always ensure you have the correct international access code for your country (e.g., 011 from the US, 00 from most European countries).
