Area Code 36 – Hesperange/Kockelscheuer/Roeser

Geographic Coverage and Administrative Jurisdiction

The +352 36 prefix is a geographic National Destination Code (NDC) assigned to the south-central region of Luxembourg, encompassing the communes of Hesperange, Kockelscheuer, and Roeser. These localities form part of the canton of Luxembourg, within the broader Luxembourg District. The area is characterized by a mix of residential suburbs, commercial zones, and light industrial parks, situated immediately south of Luxembourg City. The prefix serves fixed-line PSTN and VoIP subscribers within this defined geographic area, adhering to the ITU-T E.164 numbering plan.

Dialing Formats and Caller Instructions

Within Luxembourg, calls to numbers using the 36 prefix require dialing the full national significant number, which includes the NDC followed by the subscriber number. For example, a local call to a subscriber in Hesperange would be dialed as 36 XX XX XX (the exact subscriber number length may vary). No trunk prefix '0' is used in Luxembourg; the national dialing plan uses the direct country code format. For international callers, the number must be prefixed with the Luxembourg country code +352, resulting in the format +352 36 XX XX XX. When calling from abroad, the leading '+' is replaced with the appropriate international access code (e.g., 00 from most European countries, 011 from North America).

Overlay and Numbering Plan Considerations

Luxembourg operates a closed numbering plan with no trunk prefix, and geographic NDCs are not overlaid with other codes. The 36 prefix is exclusively assigned to the Hesperange/Kockelscheuer/Roeser area, ensuring that the geographic significance of the number is retained. Number portability applies across the country, meaning that a subscriber may retain their 36 number even if they relocate to another region, but the prefix remains associated with the original geographic allocation for routing and administrative purposes.

Practical Usage and Routing

For businesses and residents in this area, the 36 prefix is essential for local identity and cost-effective calling. Calls from mobile networks or other geographic areas within Luxembourg are typically charged at standard national rates. International calls to +352 36 numbers are subject to the caller's international tariff. VoIP users can reach these numbers using standard E.164 dialing, and emergency services (112) are accessible without any prefix. When dialing from a foreign country, ensure the correct international access code is used, and omit any leading '0' that might be part of the local dialing habit in other countries.
