Area Code 30 – Capellen/Kehlen

Geographic Context and Coverage

The +352 30 numbering block is a geographic allocation within the Luxembourg national numbering plan, serving the Capellen/Kehlen area in the southwestern part of the Grand Duchy. This region, part of the canton of Capellen, includes the communes of Kehlen, Mamer, and Strassen, among others. The prefix is used for fixed-line PSTN services, connecting subscribers within this administrative district. Unlike mobile or non-geographic numbers, +352 30 numbers are tied to a physical location and are typically assigned to residential and business landlines.

Dialing Formats and Number Structure

Luxembourg uses a closed dialing plan, meaning that the full national significant number (NSN) is always dialed locally, including the leading '0' (if present) or the country code. For +352 30 numbers, the NSN is 9 digits long, starting with '30'. The format is: +352 30 XX XX XX (or 30 XX XX XX when dialed within Luxembourg). When calling from abroad, you dial the international access code (e.g., 00 from most countries), followed by the Luxembourg country code 352, and then the subscriber number without any leading zero. For example, a local number might be 30 12 34 56; from the US, you would dial 011 352 30 12 34 56.

Caller Instructions

For local callers within Luxembourg, simply dial the 9-digit number starting with 30. No trunk prefix is required. For international callers, always use the +352 country code. Be aware that while most numbers are 9 digits, some older allocations might have been shorter; however, the current standard is 9 digits. If you encounter a number with fewer digits, it may be outdated or misprinted.

Overlay and Numbering Plan Considerations

Luxembourg does not use area code overlays in the traditional sense; instead, geographic prefixes like 30 are part of the national numbering plan. Number portability allows subscribers to retain their numbers when switching providers, but geographic numbers are generally not portable outside their designated region. VoIP services may also use geographic numbers, but they are not tied to a physical line.

Practical Examples

• Calling a fixed line in Kehlen from abroad: +352 30 45 67 89
• Calling the same number from a Luxembourg mobile: 30 45 67 89
• International format for SMS or fax: +352 30 45 67 89

Always verify the number length and format with your contact, as misdialing can lead to unintended destinations.
