📍 Geographic Location of Rumelange

Geographic Overview and Jurisdiction

The +352 56 prefix is a geographic National Destination Code (NDC) assigned to the town of Rumelange, located in the canton of Esch-sur-Alzette in southwestern Luxembourg, near the French border. This area is part of the historic Red Lands (Terres Rouges) region, known for its former iron ore mining industry. Administratively, Rumelange is a commune with a population of approximately 5,600 residents. The prefix covers the town center and its immediate surroundings, including the localities of Haut-Rumelange and Bas-Rumelange. It is important to note that Luxembourg's numbering plan is fully closed, meaning the national significant number (NSN) is always 9 digits long, including the leading '56'. There are no overlay codes in Luxembourg; each geographic area has a unique prefix, and local numbers are not portable across different geographic NDCs.

Dialing Formats and Caller Instructions

For callers within Luxembourg, the national format requires dialing the full 9-digit number, including the leading '56'. For example, a local Rumelange number would be dialed as 56 12 34 56 (using the standard 2-2-2 grouping). No trunk prefix '0' is used in Luxembourg, so you simply dial the NDC followed by the subscriber number. For international callers, the format is +352 56 12 34 56 or 00 352 56 12 34 56 from most European countries. When calling from a mobile phone, the plus sign (+) is typically used. It is essential to omit any leading '0' that might be part of the local dialing habit from other countries, as Luxembourg does not use a trunk prefix. Calls to this geographic number are charged at standard landline rates, depending on the caller's operator and subscription plan.

Numbering and Technical Details

The subscriber numbers associated with the +352 56 prefix are 6 digits long, resulting in a total NSN length of 9 digits (e.g., 56 12 34 56). These numbers are allocated to fixed-line services, including PSTN and VoIP, and are primarily used by residential and business customers within Rumelange. The Luxembourg Institute of Regulation (ILR) oversees the allocation of numbering resources. As with all fixed geographic numbers in Luxembourg, calls to +352 56 are routed via the public switched telephone network (PSTN) or IP-based networks, depending on the operator. There are no special premium-rate or service-related restrictions associated with this prefix; it is a standard geographic code. For emergency services, callers should always dial 112, regardless of the prefix.
