Area Code 35 – Sandweiler/Moutfort/Roodt-sur-Syre

Geographic Coverage and Administrative Jurisdiction

The +352 35 prefix is a geographic National Destination Code (NDC) assigned to the central-eastern region of the Grand Duchy of Luxembourg, specifically serving the communes of Sandweiler, Moutfort, and Roodt-sur-Syre. These localities fall under the canton of Luxembourg and are situated within the broader administrative district of Luxembourg City. The area is characterized by a mix of residential suburbs and light commercial zones, benefiting from proximity to the capital and excellent transport links via the A1 motorway.

Dialing Formats and Number Structure

In Luxembourg, the national numbering plan follows a closed dialing plan, meaning that the full national significant number (NSN) must always be dialed, both for local and national calls. The NSN for numbers under the 35 prefix is 9 digits long, beginning with the NDC '35' followed by a 7-digit subscriber number. For example, a typical number would be formatted as 35 12 34 56 when dialed domestically. When calling from abroad, the international format is +352 35 12 34 56, where the leading '0' is not used (Luxembourg does not use trunk prefixes).

Caller Instructions

• Local callers (within Luxembourg): Dial the full 9-digit number starting with 35. For instance, to reach a subscriber in Sandweiler, dial 35 12 34 56.
• International callers: Dial the international access code (00 or +), followed by the country code 352, then the 9-digit number without any leading zero. Example: +352 35 12 34 56.

Overlay and Numbering Plan Considerations

Luxembourg does not employ area code overlays; each geographic region has a distinct NDC. The 35 prefix is exclusively assigned to the Sandweiler-Moutfort-Roodt-sur-Syre area and is not shared with other regions. This ensures unambiguous routing and simplifies dialing for users. The national regulator, Institut Luxembourgeois de Régulation (ILR), manages the allocation of these codes, and number portability is available, allowing subscribers to retain their numbers when changing operators, though the geographic significance of the prefix remains tied to the original location.

Practical Examples

For a business in Moutfort, the published number might be 35 98 76 54. A customer in Germany would dial 00 352 35 98 76 54 or use the plus notation +352 35 98 76 54. A resident in Luxembourg City would simply dial 35 98 76 54. This straightforward approach eliminates confusion and ensures efficient call completion.
