Area Code 2745 – Diedrich

Geographic Scope and Administrative Jurisdiction

The +352 2745 prefix is a geographic numbering resource allocated within the Luxembourg national numbering plan, specifically serving the locality of Diedrich. Diedrich is a small rural settlement situated in the commune of Waldbillig, within the canton of Echternach, in the eastern part of the Grand Duchy of Luxembourg. This area falls under the administrative jurisdiction of the Institut Luxembourgeois de Régulation (ILR), the national regulatory authority responsible for assigning and managing all telecommunications numbering resources in accordance with the ITU-T E.164 recommendation and national legislation.

Dialing Formats and Caller Instructions

In Luxembourg, the national numbering plan operates under a closed dialing system, meaning that the full national significant number (NSN) must always be dialed, even for local calls. The NSN for numbers within the 2745 prefix is 9 digits long, beginning with the prefix itself. Therefore, a typical subscriber number in Diedrich would appear as 2745 xx xx (where x represents a digit).

• Local callers (within Luxembourg): Dial the full 9-digit number directly, e.g., 2745 12 34. No trunk prefix (such as '0') is used.
• International callers: Dial the Luxembourg country code +352, followed by the 9-digit national number, omitting any leading zero. For example, from abroad, you would dial +352 2745 12 34 or 00352 2745 12 34 depending on your country's international access code.

Overlay and Numbering Plan Considerations

Luxembourg does not employ area code overlays in the traditional sense; instead, the entire country uses a single country code (+352) with geographic prefixes that are integrated into the national number. The 2745 prefix is part of the geographic numbering ranges assigned to fixed-line services in the eastern region. Due to the small geographic size of Luxembourg and the implementation of number portability, a number beginning with 2745 may not always physically terminate in Diedrich; it could be ported to another operator or location. However, the prefix retains its original geographic designation for administrative and routing purposes.

Services and Usage

Subscribers under the 2745 prefix are typically connected to the public switched telephone network (PSTN) or VoIP services, provided by incumbent operator POST Luxembourg or alternative carriers. These lines are used for residential and business purposes, offering standard voice telephony, fax, and broadband services. When calling a 2745 number, the caller is connected to a line that is geographically associated with the Diedrich area, which can be important for local businesses that wish to establish a regional presence.
