Geographic Overview
The +352 2452 prefix is a geographic numbering resource allocated within the Luxembourg public switched telephone network (PSTN). Specifically, it serves the town of Dudelange, located in the canton of Esch-sur-Alzette in southern Luxembourg, near the French border. Dudelange is the fourth-largest city in the Grand Duchy and forms part of the country's industrial heartland. The prefix is assigned to fixed-line services, including residential and business subscribers, within this locality.
Dialing Formats
Luxembourg uses a closed dialing plan, meaning the national significant number (NSN) is always eight digits long, and the country calling code +352 is required for international calls. The prefix 2452 is part of the NSN; there is no separate trunk prefix like '0' used in many other countries.
- National calls (within Luxembourg): Dial the eight-digit subscriber number directly, e.g., 24 52 12 34.
- International calls (from abroad): Dial the international access prefix (00 or +), then 352, followed by the eight-digit number, e.g., +352 24 52 12 34.
- Local calls: Within Dudelange, you still dial the full eight-digit number; no local abbreviated dialing is used.
Regulatory and Technical Notes
The Institut Luxembourgeois de Régulation (ILR) oversees numbering assignments in Luxembourg. Geographic numbers like 2452 are tied to a physical address for billing and emergency services (112). However, number portability allows subscribers to retain their 2452 number when moving to a different operator, though the number remains associated with the Dudelange geographic area.
For callers from abroad, it is essential to omit any leading '0' that might be part of a local notation; Luxembourg numbers do not include a trunk prefix. When dialing from a mobile phone, using the plus sign (+) followed by 352 is the most reliable method.
Businesses in Dudelange often use this prefix to establish a local presence, and callers should be aware that tariffs for calling +352 2452 numbers depend on their own telecom provider's international rate schedule. For emergency services, always dial 112 within Luxembourg, regardless of the prefix.
