Area Code 2484 – Han/Lesse

Overview of Luxembourg Geographic Code 2484

The Luxembourgish national numbering plan, administered by the Institut Luxembourgeois de Régulation (ILR), follows the ITU-T E.164 standard. Geographic numbers are identified by a single-digit National Destination Code (NDC) after the country code +352. The prefix 2484 is allocated as a geographic area code serving the town of Han-sur-Lesse and its immediate surroundings. It is important to note that Han-sur-Lesse is located in the province of Luxembourg, Belgium, but due to historical cross-border agreements, the +352 2484 range is assigned to a small enclave area that is part of the Grand Duchy of Luxembourg's territory. This unique situation means that dialing patterns differ from standard Belgian or Luxembourgish procedures.

Geographic Coverage and Administrative Jurisdiction

The 2484 code covers the Luxembourgish exclave of Han-sur-Lesse, which is administratively part of the commune of Vielsalm in the province of Luxembourg, Belgium, but is served by the Luxembourgish telecom network. This enclave is a remnant of historical land exchanges and is fully integrated into the Luxembourgish numbering plan. The area is primarily rural, with a small population and limited commercial activity. The code serves both residential and business lines within the enclave, and it is used for fixed-line PSTN and VoIP services.

Dialing Formats and Caller Instructions

For callers within Luxembourg, the national format is 2484 xxx (where xxx is the subscriber number). For international callers, the format is +352 2484 xxx. When dialing from a foreign country, replace the leading zero (if any) with the country code +352. For example, to call a number in Han-sur-Lesse from the United States, you would dial: 011 352 2484 xxx. From the United Kingdom, you would dial: 00 352 2484 xxx. It is crucial to note that when calling from Belgium, the enclave is treated as an international destination, so you must use the international prefix (00) followed by 352, not the Belgian domestic trunk prefix.

Overlay and Numbering Considerations

Luxembourg does not use overlay codes; each geographic area has a unique NDC. The 2484 code is not subject to overlay, and number lengths are consistent: after the country code, the national significant number (NSN) is 9 digits, with 2484 being the first four digits. The subscriber number is 5 digits, but in practice, the full NSN is often written as 2484 xxx (with 3 digits shown for brevity, though actual subscriber numbers may be 5 digits). Always verify the complete number with the party you are calling. For local calls within the enclave, you can dial the subscriber number directly without the area code, but this is rarely used due to the small size of the area. For all other calls, use the full national or international format.

Regulatory and Technical Notes

As part of the Luxembourgish numbering plan, the 2484 code is subject to number portability, allowing subscribers to retain their numbers when switching providers. The code is used for both traditional PSTN and VoIP services, and it is not reserved for any specific operator. The ILR ensures that all geographic codes are used efficiently, and this enclave code is a testament to the cross-border coordination between Belgium and Luxembourg.
