Area Code 39 – Windhof/Steinfort

Geographic Coverage and Administrative Jurisdiction

The +352 39 prefix is a geographic National Destination Code (NDC) assigned to the Windhof/Steinfort area in the Grand Duchy of Luxembourg. This region falls under the administrative jurisdiction of the Canton of Capellen, in the western part of the country, near the Belgian border. The code serves the town of Steinfort and its surrounding localities, including Windhof, which is a major commercial and logistics hub. The area is known for its business parks and residential communities, making the prefix common for both corporate offices and private households.

Dialing Formats and Number Structure

Luxembourg uses a closed dialing plan, meaning that the full national significant number (NSN) must always be dialed, even for local calls. The NSN for this geographic prefix is 9 digits long, starting with the NDC '39' followed by a 7-digit subscriber number. For example, a typical number would be formatted as 39 12 34 56 when dialed domestically. Internationally, callers must dial the Luxembourg country code (+352) followed by the NSN, omitting any trunk prefix (there is none). Thus, the international format is +352 39 12 34 56.

Caller Instructions

Local callers (within Luxembourg) should dial the full 9-digit number, e.g., 39 12 34 56, without any leading '0'. International callers should dial their country's international access code (e.g., 011 from the US, 00 from most European countries), then the Luxembourg country code 352, followed by the subscriber number 39 12 34 56. There is no area code trunk prefix in Luxembourg, so the number remains the same regardless of the caller's location.

Overlay Considerations

Luxembourg does not use overlay codes; each geographic area has a unique NDC. However, due to the small size of the country and the high density of telecommunications infrastructure, some geographic codes may be used by alternative service providers, but the '39' prefix remains specifically associated with the Windhof/Steinfort area. Number portability is available, so a number with this prefix may be reassigned to a different operator, but the geographic significance remains for routing purposes.

Practical Usage and Examples

Businesses in the Windhof business park often use numbers like +352 39 78 45 12 for their main lines. For instance, a logistics company might list its contact as +352 39 21 45 78. When calling from abroad, ensure you replace the '+' with your international access code. For example, from the UK, you would dial 00 352 39 21 45 78. From the US, you would dial 011 352 39 21 45 78.

Understanding the correct dialing format is crucial for both personal and business communications to ensure seamless connectivity with the Windhof/Steinfort area.
