Geographic Overview
The +352 2645 numbering range is a geographic allocation within the Luxembourg public switched telephone network (PSTN), specifically assigned to the locality of Diedrich (also spelled Diederen or Diedrichs). This area falls under the administrative jurisdiction of the Commune of Junglinster, situated in the canton of Grevenmacher in central-eastern Luxembourg. The code serves a predominantly rural and residential catchment, with Diedrich itself being a small village. However, the numbering range may also cover nearby hamlets and scattered dwellings within the same exchange area, as is typical for low-density geographic allocations in the Grand Duchy.
Dialing Formats and Procedures
Luxembourg employs a closed numbering plan, meaning the full national significant number (NSN) is always 9 digits, including the leading '2' for geographic numbers. The area code '2645' is not a separate trunk prefix but an integral part of the subscriber number. Therefore, the complete national number for a Diedrich landline would be formatted as 2645 XX XX (where X represents the subscriber's unique digits).
- Local calls within Luxembourg: Dial the full 9-digit number directly, e.g., 2645 12 34. No trunk prefix '0' is used.
- International calls from abroad: Dial the international access prefix (00 or +), followed by Luxembourg's country code 352, and then the full 9-digit number. For example, from the United States, you would dial 011 352 2645 12 34; from most European countries, 00 352 2645 12 34.
Regulatory and Technical Notes
The Institut Luxembourgeois de Régulation (ILR) oversees numbering assignments. Geographic numbers like 2645 are traditionally associated with fixed-line services, but since the liberalization of the telecom market, such numbers may be used by VoIP providers or resellers, though they remain tied to the geographic location for tariff and emergency call routing purposes. Overlay codes are not applicable in Luxembourg due to the closed plan and sufficient numbering capacity. Callers should note that while the code is geographically assigned, the actual physical location of the called party may vary if number portability has been exercised, though this is less common for fixed geographic numbers.
For businesses or residents in Diedrich, having a 2645 number reinforces a local presence. When calling from a mobile phone within Luxembourg, the same 9-digit number is used. For international callers, always omit any leading '0' that might appear in local directories (though none exists for Luxembourg). The cost of calling a 2645 number depends on the caller's operator and tariff plan, but it is generally charged as a standard fixed-line call to a geographic destination.
