Area Code 78 – Junglinster

Geographic Significance and Coverage

The +352 78 prefix is a geographic National Destination Code (NDC) assigned to the Junglinster area in the Grand Duchy of Luxembourg. Junglinster is a commune and town in the canton of Grevenmacher, located in the eastern part of the country, approximately 15 kilometers northeast of Luxembourg City. The code serves the town itself and the surrounding localities, including Altlinster, Blumenthal, Bourglinster, Eisenborn, Gonderange, Graulinster, Imbringen, and Lellig. As part of Luxembourg's national numbering plan, the prefix is used for fixed-line PSTN services, and it is administered by the Institut Luxembourgeois de Régulation (ILR), the national regulatory authority.

Dialing Formats and Caller Instructions

Luxembourg uses a closed telephone numbering plan, meaning that the full national (significant) number must always be dialed, even for local calls. The national number for Junglinster subscribers consists of the NDC '78' followed by a four-digit subscriber number, resulting in a six-digit total length. For example, a local number might be 78 12 34.

• Domestic calls (within Luxembourg): Dial the full national number: 78 12 34. There is no trunk prefix (such as '0') used in Luxembourg; the number is dialed exactly as it appears.
• International calls from abroad: Dial the international access prefix (e.g., 00 from most countries, or '+' from mobile phones), followed by Luxembourg's country code +352, and then the subscriber number without any leading zero: +352 78 12 34.

It is important to note that when calling from a foreign country, callers must not add a '0' before the '78', as Luxembourg's numbering plan does not use a trunk prefix. The correct international format is +352 78 XX XX.

Overlay and Numbering Considerations

As of the latest ILR updates, there is no overlay code for the Junglinster area; the 78 prefix remains the sole geographic code for this region. However, number portability is available in Luxembourg, allowing subscribers to retain their numbers when changing operators, but this does not affect the geographic significance of the prefix. For callers, this means that a number starting with 78 will always be associated with the Junglinster exchange area, regardless of the service provider.

Practical Usage for Businesses and Residents

Businesses and residents in Junglinster use the 78 prefix for their fixed-line services. For international callers, it is essential to use the correct format to avoid misdialing. For example, a business in Junglinster with the number 78 45 67 would be reached internationally at +352 78 45 67. Local callers within Luxembourg simply dial 78 45 67. Understanding these dialing rules ensures seamless connectivity with this historic and scenic region of Luxembourg.
