Area Code 88 – Mertzig/Wahl

Geographic Coverage and Administrative Jurisdiction

The +352 88 numbering range is a geographic allocation within the Luxembourg national numbering plan, specifically assigned to the communes of Mertzig and Wahl. These localities are situated in the canton of Diekirch, in the central-northern part of the Grand Duchy of Luxembourg. The area is characterized by its rural landscape and close-knit communities, with Mertzig serving as the primary administrative and commercial hub. Wahl, a smaller commune, lies to the northwest, and both are part of the broader Redange region, which borders Belgium to the west.

Dialing Formats and Number Structure

In Luxembourg, the national significant number (NSN) for geographic services is typically composed of the area code (1 to 2 digits) followed by a subscriber number. For the +352 88 range, the full national number is usually 9 digits long, including the leading '88'. For example, a local number might appear as 88 12 34 56 when dialed domestically. When calling from abroad, the international format requires the country code +352, followed by the NSN without any leading zero: +352 88 12 34 56. It is important to note that Luxembourg does not use trunk prefixes like '0'; therefore, international callers must not add a '0' after the country code.

Caller Instructions

• Local callers (within Luxembourg): Simply dial the 9-digit national number, e.g., 88 12 34 56. No area code separation is needed; the entire sequence is dialed.
• International callers: Dial the international access prefix (e.g., 00 from most countries, or '+' from mobile phones), then the Luxembourg country code 352, followed by the subscriber number 88 12 34 56. Example: +352 88 12 34 56.

Overlay and Numbering Plan Considerations

Luxembourg's numbering plan is closed, meaning that all numbers, both geographic and mobile, have a fixed length. The country has implemented number portability, allowing subscribers to retain their numbers when changing operators, but geographic numbers are generally tied to the physical location of the line. As of the latest ITU-T E.164 guidelines, there are no overlay codes in Luxembourg; each geographic area has a unique prefix. The 88 range is exclusively used for the Mertzig/Wahl area, and no other geographic code overlays this region.

Practical Usage and Examples

Businesses and residents in Mertzig and Wahl use numbers in the 88 range for fixed-line telephony, including PSTN and VoIP services. When listing a number on a website or business card, it is common to display it in international format, e.g., +352 88 12 34 56, to facilitate calls from abroad. For local directories, the number may appear as 88 12 34 56.
