Geographic Overview of Luxembourg's 52 Prefix

The +352 52 prefix is a geographic National Destination Code (NDC) assigned to the southern region of Luxembourg, specifically serving the city of Dudelange and its surrounding communes. Dudelange, located in the canton of Esch-sur-Alzette, is one of the country's major industrial and residential hubs, situated near the French border. This prefix is used for fixed-line PSTN (Public Switched Telephone Network) services within this area.

Dialing Formats and Procedures

Luxembourg employs a closed telephone numbering plan, meaning that the full national number (including the NDC) must always be dialed, even for local calls. The national number for a subscriber in Dudelange typically consists of the NDC '52' followed by a 4-digit subscriber number, resulting in a total length of 6 digits. For example, a local number might be formatted as 52 12 34.

  • Local calls (within Luxembourg): Dial the full national number: 52 12 34.
  • International calls from abroad: Dial the international access prefix (e.g., 00 from most countries, or + from mobile), then the Luxembourg country code +352, followed by the national number: +352 52 12 34.

It is important to note that Luxembourg does not use trunk prefixes (like '0' in many countries). Therefore, when calling from abroad, you do not drop any leading zero—simply dial +352 followed by the complete national number.

Administrative and Geographic Coverage

The 52 prefix covers the city of Dudelange and may also serve adjacent localities within the same exchange area. Dudelange is known for its steel industry heritage and is part of the broader Esch-sur-Alzette canton, which is the second-largest urban area in Luxembourg. The prefix is allocated for fixed-line services, and as with all geographic numbers in Luxembourg, it is subject to number portability, allowing subscribers to retain their numbers when switching providers.

Caller Instructions

For callers within Luxembourg, simply dial the 6-digit national number. For international callers, ensure you use the correct international format: +352 followed by the national number. Avoid omitting the '52' prefix, as it is essential for routing the call to the correct geographic region.
