Area Code 2736 – Hesperange/Kockelscheuer/Roeser

Overview of Luxembourg Geographic Code 2736

The prefix 2736 is a geographic National Destination Code (NDC) within the Luxembourg national numbering plan, aligned with ITU-T E.164 recommendations. It serves the southern-central region of the Grand Duchy, specifically the communes of Hesperange, Kockelscheuer, and Roeser. These localities form part of the canton of Luxembourg and are situated in close proximity to the capital, Luxembourg City, within the broader agglomeration.

Geographic Coverage and Administrative Context

Hesperange is a commune located to the southeast of Luxembourg City, known for its residential areas and the historic Hesperange Castle. Kockelscheuer, a small town within the commune of Roeser, lies to the south and is notable for its recreational facilities and conference center. Roeser itself is a rural commune that includes several villages. The 2736 prefix is assigned to fixed-line PSTN and VoIP services within these areas, reflecting the traditional geographic allocation of numbers based on the location of the subscriber's physical connection.

Dialing Formats and Procedures

For callers within Luxembourg, the national format requires dialing the full 9-digit subscriber number, which includes the leading '2' of the area code. For example, to reach a fixed line in Hesperange, you would dial 2736 1234 (where 1234 is the local subscriber number). No trunk prefix '0' is used in Luxembourg; the national significant number (NSN) is always 9 digits.

For international callers, the format is +352 2736 1234. The plus sign represents the international access code, followed by Luxembourg's country code 352, and then the NDC and subscriber number. Callers from abroad must omit any leading '0' (though none exists) and should replace the '+' with their country's international exit code (e.g., '00' from most European countries, '011' from the United States).

Numbering Plan and Overlays

Luxembourg operates a closed numbering plan with no area code overlays; each geographic region has a unique NDC. The 2736 prefix is exclusively assigned to the Hesperange/Kockelscheuer/Roeser area, and there are no plans for overlay codes. Subscribers in this region can keep their numbers when moving within the same geographic area, but number portability allows them to retain the number even if they relocate to another part of the country, as long as the service provider supports it.

Practical Guidance for Callers

• Local callers within Luxembourg should dial the 9-digit number directly (e.g., 2736 1234).
• International callers should dial +352 2736 1234.
• Emergency services (112) are always free and accessible regardless of the prefix.
• When calling from a mobile phone, the same international format applies if you are outside Luxembourg.
