Area Code 29 – Luxembourg/Kockelscheuer

Geographic Overview

The +352 29 prefix is a geographic National Destination Code (NDC) assigned to the Kockelscheuer area, a locality within the administrative jurisdiction of Luxembourg City, in the Grand Duchy of Luxembourg. Kockelscheuer is situated in the southern part of the capital, near the French border, and is known for its recreational facilities, including a golf course and an ice rink. The prefix serves fixed-line PSTN (Public Switched Telephone Network) subscribers in this specific exchange area.

Dialing Format

For international callers, the number must be dialed as +352 29 followed by the subscriber's local number. In Luxembourg's national numbering plan, geographic numbers typically consist of the NDC (1-2 digits) plus a subscriber number, with a total length of 9 digits (including the leading '352' country code). For example, a local number might be formatted as +352 29 123 456 when dialed from abroad. Within Luxembourg, callers can dial the national significant number directly, often omitting the trunk prefix '0' (which is not used in Luxembourg). Thus, a domestic call to the same number would be dialed as 29 123 456.

Geographic Allocation and Overlay

The 29 prefix is part of the geographic numbering plan managed by the Institut Luxembourgeois de Régulation (ILR), the national regulatory authority. It is allocated to fixed-line services, and numbers under this prefix are tied to a physical location in Kockelscheuer. There are no overlay codes currently in effect for this area; the prefix is exclusive to this exchange. However, number portability allows subscribers to retain their 29 numbers even if they move to a different geographic location within Luxembourg, provided the service provider supports it.

Caller Instructions

For local callers within Luxembourg, simply dial the 9-digit national number (e.g., 29 123 456). For international callers, always use the +352 country code followed by the 29 prefix and the subscriber number. When calling from a mobile phone, the same international format applies. It is important to note that Luxembourg uses a closed dialing plan, so there is no trunk prefix like '0' to be added. Ensure you have the correct number of digits after the prefix, as subscriber numbers in Luxembourg can vary in length, typically between 4 and 6 digits.
