Huldange is a small village situated in the commune of Troisvierges, in the far north of the Grand Duchy of Luxembourg, within the canton of Clervaux. This area lies in the Ardennes region, near the borders with Belgium and Germany, and is part of the country's rural northern district.

The number is used for both residential and business fixed-line services, including PSTN and VoIP-based fixed connections that are registered to a local exchange.

Dialing Format

Luxembourg uses a closed telephone numbering plan, meaning that the national significant number (NSN) is always 9 digits long, including the leading '2' for geographic numbers. The country calling code is +352.

• National dialing (within Luxembourg): 2497 XX XX (subscriber number is 5 digits after the prefix, making the total NSN 9 digits: 2497 + 5 digits).
• International dialing (from abroad): +352 2497 XX XX (drop any leading '0' – Luxembourg does not use trunk prefix '0').

For example, a local number in Huldange might be +352 2497 1234 (if the subscriber number is 1234) or +352 2497 12345 (if the subscriber number is 12345). Always verify the exact subscriber number length with the service provider.

Caller Instructions

For callers within Luxembourg: Simply dial the 9-digit national number, e.g., 2497 1234. No trunk prefix is required.

Overlay and Number Portability

Luxembourg does not use overlay area codes; the entire country is a single numbering plan area. Geographic numbers like 2497 are not portable to other geographic areas, but they can be ported to VoIP or mobile operators while retaining the original prefix, as per national number portability rules. However, the number's geographic association remains for routing and emergency services purposes.

For businesses, having a 2497 number signals a local presence in Huldange, which can be beneficial for customer trust and local marketing. For residents, it ensures that calls are treated as local calls within the national tariff structure.
