Luxembourg numbering plan & how to dial
Under country code +352, Luxembourg runs a closed numbering plan — just a 8-digit subscriber number after the country code, no area code required.
3 major networks cover Luxembourg (POST Luxembourg, Tango, Orange Luxembourg), against 98% internet penetration. VoIP is permitted and regulated by ILR (Institut Luxembourgeois de Régulation). Because Luxembourgish, French, German is the primary language and EUR the local currency, both should inform IVR scripts, SMS content, and support hours.
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
Luxembourg calls from the US need 011 first, then +352 — the exit code isn't optional.
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
Before dialing Luxembourg, check the local clock — it runs on UTC+1, and off-hours calls tend to go unanswered.
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).

FAQ
Calling Luxembourg — frequently asked questions
