Area Code 48 – Contern/Foetz

Geographic Overview

The +352 48 prefix is a geographic National Destination Code (NDC) assigned to the Contern and Foetz area in the Grand Duchy of Luxembourg. Contern is a commune located in the southern part of the country, within the canton of Luxembourg, and includes the town of Contern itself as well as the smaller localities of Moutfort, Oetrange, and Medingen. Foetz, on the other hand, is a small town in the commune of Mondercange, in the canton of Esch-sur-Alzette. Both areas are part of the country's central and southern economic corridor, with Contern situated just southeast of Luxembourg City and Foetz lying to the southwest, near the industrial heartland around Esch-sur-Alzette.

Dialing Formats

Luxembourg uses a closed telephone numbering plan, meaning that the full national (significant) number must always be dialed, even for local calls. The national number for subscribers in the Contern/Foetz area begins with the NDC '48' followed by a subscriber number of variable length, typically 3 to 4 digits. Therefore, the complete national number is usually 6 to 7 digits long (e.g., 48 1234).

• National calls (within Luxembourg): Dial the full number starting with '48', e.g., 48 1234.
• International calls from abroad: Dial the international access prefix (00 or +), then the Luxembourg country code 352, followed by the national number without any leading zero (Luxembourg does not use trunk prefixes). For example, to call a number in Contern from the US, you would dial 011 352 48 1234.

Numbering Plan Details

Luxembourg's numbering plan, administered by the Institut Luxembourgeois de Régulation (ILR), follows ITU-T E.164 recommendations. Geographic NDCs are allocated based on exchange areas, and the '48' prefix is one of several assigned to the southern and central regions. Unlike some countries, Luxembourg does not use overlay codes or area code changes; the geographic significance is primarily for routing and administrative purposes, and subscribers may keep their numbers when moving within the same exchange area.

Caller Instructions

For local callers within the Contern/Foetz area, it is essential to remember that even a call to a neighbor requires dialing the full national number, as there are no local dialing shortcuts. For international callers, it is crucial to omit any leading '0' (none exists) and to use the correct international prefix for their country. For example, from the UK, you would dial 00 352 48 1234.

As with all geographic numbers in Luxembourg, calls to +352 48 numbers are typically charged at standard national rates when dialed from within the country, and at international rates when dialed from abroad. These numbers are primarily used for fixed-line services, including PSTN and VoIP, and are not portable to mobile networks.
