Luxembourg numbering plan & how to dial
Luxembourg uses a closed numbering plan under country code +352: subscribers are reached with a single 8-digit number after the country code, with no separate area code to dial.
Luxembourg has 98% internet penetration and is served by 3 major mobile networks (POST Luxembourg, Tango, Orange Luxembourg). VoIP is permitted and regulated by ILR (Institut Luxembourgeois de Régulation). The local currency is EUR and the primary language is Luxembourgish, French, German, which shape IVR prompts, SMS content, and business-hours handling.
Most European numbering plans follow ITU-T E.164 with a national trunk prefix that is dropped for international dialing, and cross-border VoIP is widely supported across the region.
Skipping the exit code
From the US you must dial 011 before the +352 country code to reach Luxembourg.
Adding an area code that doesn't exist
Luxembourg uses a closed plan — dial the +352 country code then the 8-digit subscriber number directly, with no area code.
Ignoring the time difference
Luxembourg runs on UTC+1. Check local hours before dialing so calls don't land outside business time.
Permitted — ILR regulated
Regulated by ILR (Institut Luxembourgeois de Régulation)
- VoIP operators must obtain authorisation from ILR under the Law of 27 February 2011 on Electronic Communications Networks.
- Emergency service access (112) is required for all authorised VoIP providers serving Luxembourg users.
- GDPR enforcement is managed by the CNPD (Commission Nationale pour la Protection des Données).
