Area Code 87 – Larochette

Overview of Luxembourg Area Code 87

Area code 87 in Luxembourg is a geographic National Destination Code (NDC) assigned to the town of Larochette and its surrounding areas. Located in the central-eastern part of the Grand Duchy, Larochette is known for its medieval castle and scenic valleys. The code 87 is part of the national numbering plan administered by the Institut Luxembourgeois de Régulation (ILR), following ITU-T E.164 recommendations.

Geographic Coverage and Administration

The 87 prefix covers the administrative commune of Larochette, which includes the town itself and nearby localities such as Ernzen and Bourglinster. This region falls under the canton of Mersch, in the district of Grevenmacher. As a geographic code, it is tied to the physical location of the subscriber's line, typically served by fixed-line PSTN or VoIP providers offering local numbers.

Dialing Formats

For local callers within Luxembourg, the number is dialed as an eight-digit national significant number (NSN) that includes the leading '87'. For example, a local number might be 87 12 34 56. When calling from abroad, the full international format is required: +352 87 12 34 56. The country code for Luxembourg is +352, and the trunk prefix '0' is not used in Luxembourg, so international callers simply dial +352 followed by the NSN.

Number Structure and Overlays

Luxembourg uses a closed numbering plan with no trunk prefix. All geographic numbers, including those starting with 87, have a fixed length of 8 digits (including the NDC). There are no overlay codes in Luxembourg; each geographic area has a unique NDC. This simplifies dialing and ensures that the 87 prefix unambiguously identifies Larochette and its environs.

Caller Instructions

For local callers within Luxembourg, simply dial the 8-digit number. For international callers, replace the leading '87' with '+352 87' when dialing from a mobile or fixed line. For example, to call a number in Larochette from the United States, you would dial 011 352 87 12 34 56. From a mobile phone, you can use the plus sign: +352 87 12 34 56.

Service Considerations

Geographic numbers in Luxembourg are primarily used for fixed-line services, but they can also be assigned to VoIP subscribers who may be located elsewhere. However, the number remains associated with the Larochette area for regulatory and emergency services purposes. When calling these numbers, standard national call rates apply for domestic calls, and international rates apply for calls from abroad. There are no special restrictions, but it is advisable to check with your service provider for any specific charges.
