Area Code 2784 – Han/Lesse

Overview of Luxembourgish Geographic Numbering

In the Grand Duchy of Luxembourg, the national numbering plan follows ITU-T E.164 recommendations, with country calling code +352. Geographic numbers are allocated to fixed-line services and are associated with specific administrative areas, although the small size of the country means that local calls are not subject to trunk prefixes. The national significant number (NSN) for geographic services is typically nine digits in length, beginning with a two-digit area code that identifies the geographic region.

The 2784 Prefix and the Han/Lesse Region

The prefix 2784 is a geographic area code assigned to the Han/Lesse region, a picturesque area in the Ardennes, known for its natural beauty and the famous caves of Han-sur-Lesse. This code is used by fixed-line subscribers in that locality, including residential, business, and administrative numbers. The full national number format is 2784 xx xxx, where the remaining digits represent the local subscriber number. When dialed from abroad, the international format is +352 2784 xx xxx.

Dialing Instructions

• Local calls within Luxembourg: Dial the eight-digit subscriber number directly, e.g., 2784 12 345. No trunk prefix is required.
• International calls from abroad: Dial the international access prefix (00 or +), followed by the country code 352, then the subscriber number without any leading zero, e.g., +352 2784 12 345.
• Calls from Luxembourg to other countries: Dial 00 followed by the destination country code and the national significant number.

Regulatory and Technical Considerations

Luxembourg's telecommunications regulator, the Institut Luxembourgeois de Régulation (ILR), administers the numbering plan. Geographic numbers are portable within the same geographic area, allowing subscribers to retain their numbers when changing operators. As of recent years, Luxembourg has implemented number portability across all services, including fixed and mobile. The 2784 prefix is exclusively for fixed-line services; mobile numbers in Luxembourg are identified by prefixes starting with 6 (e.g., 621, 661, 691) and are non-geographic.

For callers, it is important to note that calls to geographic numbers are typically charged at standard local rates, depending on the caller's operator and tariff plan. VoIP users may also reach these numbers, but international rates may apply if the VoIP service is based outside Luxembourg. The Han/Lesse region, being a popular tourist destination, may have businesses that rely on these numbers for reservations and inquiries, so ensuring correct dialing is essential for seamless communication.
