Area Code 74 – Wasserbillig

Overview of Luxembourg Area Code 74

Area code 74 is a geographic National Destination Code (NDC) within the Luxembourg public switched telephone network (PSTN), allocated to the town of Wasserbillig and its immediate surroundings. Wasserbillig is located in the eastern part of the Grand Duchy, at the confluence of the Sauer and Moselle rivers, directly on the border with Germany. The code serves the administrative commune of Mertert, which includes the localities of Mertert and Wasserbillig.

Geographic Coverage and Administrative Jurisdiction

The 74 prefix covers a compact but economically significant area. Wasserbillig is a key river port and a transit hub for road and rail traffic between Luxembourg and Germany. The code is assigned to fixed-line services, including residential, business, and public payphones, within this specific geographic zone. It does not cover mobile numbers, which in Luxembourg are non-geographic and begin with 6 or 691.

Dialing Formats and Instructions

For callers within Luxembourg, the national dialing format requires the leading 0 before the area code. Thus, to call a fixed line in Wasserbillig, you would dial: 0 74 XX XX XX (where the local subscriber number is 6 digits long, making the total national number 8 digits after the trunk prefix).

For international callers, the Luxembourg country code is +352. The trunk prefix 0 is not used when dialing from abroad. Therefore, the international format becomes: +352 74 XX XX XX. For example, a typical number might be +352 74 12 34 56.

When dialing locally within the 74 area, it is possible to omit the area code and dial only the 6-digit subscriber number, provided you are calling from another fixed line within the same geographic exchange. However, for clarity and to avoid misdialing, it is recommended to always use the full national format.

Overlay Considerations and Numbering Plan

Luxembourg does not currently have overlay area codes for geographic numbers; each town or region has a distinct NDC. The 74 code is exclusively used for the Wasserbillig/Mertert area. The Luxembourg numbering plan is regulated by the Institut Luxembourgeois de Régulation (ILR), which ensures that geographic codes are assigned to fixed-line services and that number portability is available. This means that if a subscriber moves to a different geographic area, they may retain their number, but the area code will no longer reflect their physical location. For callers, this implies that the 74 prefix does not guarantee the called party is physically in Wasserbillig, though in practice most numbers remain associated with the area.

Caller Instructions

For local callers: dial 0 74 followed by the 6-digit subscriber number. For international callers: dial the international access prefix (e.g., 00 from most European countries, or 011 from North America), then 352, then 74, and the subscriber number. Do not include the leading 0 of the national trunk prefix.

Understanding the correct dialing format is essential for both residential and business callers to ensure seamless connectivity to Wasserbillig's fixed-line subscribers.
