Monaco numbering plan & how to dial
Monaco uses a closed numbering plan under country code +377: subscribers are reached with a single 8-digit number after the country code, with no separate area code to dial.
Monaco has 97% internet penetration and is served by 3 major mobile networks (Monaco Telecom, Orange (roaming), SFR (roaming)). VoIP is permitted and regulated by AMSN (Autorité Monégasque de Sécurité Numérique). The local currency is EUR and the primary language is French, 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 +377 country code to reach Monaco.
Adding an area code that doesn't exist
Monaco uses a closed plan — dial the +377 country code then the 8-digit subscriber number directly, with no area code.
Ignoring the time difference
Monaco runs on UTC+1. Check local hours before dialing so calls don't land outside business time.
