About Monaco Calling Code
Every country has a unique international dialing prefix; for Monaco it is +377. The ITU assigns these codes under recommendation E.164. Dial +377 after your country's exit code, then the local subscriber number. Monaco is in Europe.
The ITU-T E.164 recommendation standardizes international numbering, giving every country and territory a distinct prefix. Without the correct prefix, international calls cannot be routed to the right destination.
Where the +377 Calling Code Is Used
The country code +377 is assigned to Monaco, located in Western Europe, with the capital Monaco. This code is part of the international telephony numbering plan and is used for all calls made to Monaco from outside the country.
A number displayed as +377 … is in international format: +377 replaces the domestic trunk prefix. From abroad, always drop any leading 0 of the area code and dial +377 + area code + subscriber number.
Calling codes starting with 3 are part of the ITU's regional numbering plan for the area around Monaco, in Western Europe. When saving Monaco numbers internationally, write +377 followed by the area code without its leading 0 — this format works from every country.
Monaco Phone Number Formats
Numbers in Monaco use the standard E.164 pattern — +377, then the area code, then the subscriber number. The same layout applies to landlines and mobile phones:
📱 Number Structure
- International format: +377 [area code] [subscriber number]
- From abroad: exit code + +377 + local number (drop the trunk prefix 0)
- Within Monaco: dial the local number directly
In most countries, domestic numbers start with a trunk prefix (often 0) that must be omitted internationally: dial your exit code, then +377, then the local number as written without its leading zero.
Time Zone in Monaco
Monaco runs on Europe/Monaco, which is UTC+01:00 UTC. Schedule international calls accordingly — a convenient time for you may be very early or very late there.
