Geographic Scope and Administrative Allocation
The +352 2643 prefix is a geographic number range allocated within the Luxembourgish national numbering plan, serving the northeastern sector of Luxembourg City. Specifically, it covers the Findel area—home to Luxembourg Airport (LUX)—and the adjacent Kirchberg Plateau, a major administrative and financial district hosting European Union institutions (e.g., the European Court of Justice, European Investment Bank) and numerous corporate headquarters. The prefix is assigned under the authority of the Institut Luxembourgeois de Régulation (ILR), the national regulatory authority, and is used for fixed-line PSTN and VoIP services.
Dialing Formats and Caller Instructions
Luxembourg uses a closed dialing plan: all national numbers, including those beginning with 2643, are dialed with the full eight-digit subscriber number without any trunk prefix. For local callers within Luxembourg, dial the complete number: 26 43 XX XX. For international callers, the country code +352 is required, followed by the eight-digit number: +352 26 43 XX XX. Note that the leading '0' is not used in Luxembourg; the number begins directly with '2'. When calling from abroad, replace the '+' with your country's international access code (e.g., '00' from most European countries).
Coverage and Numbering Details
The 2643 prefix is part of the 26 geographic range, which serves the capital region. Subscribers in this range may include businesses, government institutions, and residential customers. The Kirchberg/Findel area is a key economic zone, so many numbers are used by enterprises and EU bodies. The numbering plan does not currently apply an overlay; each geographic area has a unique prefix, and number portability allows users to retain their numbers when changing providers, though the geographic significance remains tied to the original allocation.
Practical Usage Notes

For callers, be aware that calls to Luxembourg from abroad are typically charged at international rates, while domestic calls are local. VoIP users may have different tariff structures. Always verify the complete eight-digit number, as omitting digits will result in a failed call.
