Area Code 2448 – Contern/Foetz

Geographic Coverage and Administrative Jurisdiction

The +352 2448 prefix is a geographic allocation within the Luxembourg national numbering plan, serving the localities of Contern and Foetz. Contern is a commune in the canton of Luxembourg, situated southeast of Luxembourg City, while Foetz is a small town within the commune of Mondercange, located in the canton of Esch-sur-Alzette. The prefix is administered under the regulatory oversight of the Institut Luxembourgeois de Régulation (ILR), which manages the E.164 numbering resources for the Grand Duchy.

Dialing Formats and Caller Instructions

Luxembourg employs a closed dialing plan, meaning that the national significant number (NSN) is always eight digits long, and the country code +352 is required for international calls. The prefix 2448 is part of the NSN; there is no separate trunk prefix like '0' used in many other countries. For local callers within Luxembourg, dialing the eight-digit subscriber number (e.g., 2448 1234) is sufficient. International callers must dial +352 2448 1234, replacing the leading '+' with the appropriate international access code (e.g., 00 from most European countries, 011 from North America).

Numbering and Overlay Considerations

Geographic numbers in Luxembourg are not subject to overlay codes, as the country uses a single national destination code structure. The 2448 prefix is assigned to fixed-line services, typically provided by incumbent operator POST Luxembourg or alternative carriers offering PSTN and VoIP services. Subscriber numbers under this prefix follow the standard eight-digit format, with the prefix itself occupying the first four digits. There are no known plans for number exhaustion or overlay in this region, given Luxembourg's relatively small population and efficient number management.

Practical Usage and Routing

Numbers under +352 2448 are used for both residential and business lines in Contern and Foetz. For businesses, this prefix may be used for customer service lines, administrative offices, or local branches. Calls to these numbers are routed over the public switched telephone network (PSTN) or via IP-based infrastructure, depending on the service provider. When calling from abroad, it is essential to omit any leading '0' that might be part of the local dialing habit in other countries, as Luxembourg does not use a trunk prefix. For example, a number formatted locally as 2448 5678 should be dialed internationally as +352 2448 5678.

Regulatory and Technical Notes

As with all geographic numbers in Luxembourg, number portability is available, allowing subscribers to retain their numbers when changing providers within the same geographic area. However, porting does not alter the geographic significance of the prefix. The ILR ensures that numbering resources are used efficiently and in compliance with ITU-T E.164 recommendations. For troubleshooting or verification, users can consult the ILR's official numbering database or their service provider.
