Area Code 2467 – Dudelange

Geographic Context and Coverage

The +352 2467 numbering range is a geographic allocation within the Luxembourg national numbering plan, specifically designated for the city of Dudelange. Dudelange is the fourth-largest commune in Luxembourg, located in the canton of Esch-sur-Alzette in the southern part of the country, near the French border. This prefix is used for fixed-line telephone services provided to residential and business subscribers within the Dudelange exchange area. As part of the Luxembourg numbering plan, the 2467 prefix is a National Destination Code (NDC) segment that routes calls to the appropriate central office in Dudelange.

Dialing Formats and Procedures

Luxembourg uses a closed dialing plan, meaning that the full national number (including the NDC) must always be dialed, even for local calls. The national significant number (NSN) for geographic numbers in Luxembourg is typically 9 digits long, excluding the leading trunk prefix '0' used for national dialing.

• National dialing (from within Luxembourg): Dial 0 2467 12345 (replace 12345 with the subscriber's 5-digit line number). The leading '0' is the national trunk prefix.
• International dialing (from outside Luxembourg): Dial +352 2467 12345 (or 00 352 2467 12345 from most countries). The country code +352 is used, and the trunk prefix '0' is omitted.

For example, to call a Dudelange number with the local extension 67890, a caller from abroad would dial +352 2467 67890. A caller within Luxembourg would dial 02467 67890.

Overlay and Numbering Considerations

Luxembourg does not currently use overlay codes for geographic numbers; each geographic area has a distinct NDC. However, number portability is available, allowing subscribers to retain their 2467 number when moving to a different operator, but the number remains associated with the Dudelange geographic area. Callers should note that while the prefix is geographic, the actual physical location of the subscriber may vary due to portability, but the tariff and routing are based on the original geographic allocation.

Practical Guidance for Callers

For local callers within Dudelange, it is still necessary to dial the full national number, as there are no local dialing shortcuts. For international callers, always use the plus sign (+) or the international access code of your country, followed by Luxembourg's country code 352 and the full national number without the leading '0'. Ensure you have the correct number of digits: the NDC (2467) plus a 5-digit subscriber number, totaling 9 digits.

This prefix is part of the public switched telephone network (PSTN) and supports traditional voice services, including VoIP adapters that may be assigned geographic numbers. When dialing from a mobile phone, the same international format applies.
