Monaco country code +377 — call Monaco & get a number.
Entirely surrounded by France, sharing its currency and language — but phone-wise, Monaco has been strictly separate since June 21, 1996, when it broke away from France's own numbering plan. Even calls across the few-kilometer border must be dialed in full international format. Here's exactly how to dial in from the US, UK and France, the current emergency number, time and weather, and how to get a Monaco number of your own with MCM.

Monaco at a glance
The numbers and facts you need before you dial.
What is the country code for Monaco?
Monaco dials in on +377, its own country code, entirely separate from France's +33 despite being completely surrounded by French territory. The plan behind it is simple: a closed eight-digit system with no area code and no trunk prefix, in place since Monaco split from France's numbering plan on June 21, 1996 (before that, Monégasque fixed lines simply began with French area code "93"). Whether you're reaching Monaco from next door in Nice or from New York, it's the same eight digits every time.
Monaco numbers in E.164 form are written +377 followed by 8 digits (e.g. +377 9X XX XX XX).
All four mean the same thing — they connect your call to Monaco.
How to call Monaco from anywhere
Calling Monaco is a two-step affair plus your exit code: exit code, 377, then the eight digits. Nothing to drop, nothing to prepend — the flat plan means the number you were given is the number you dial.
Full example: +377 9X XX XX XX — eight digits, no area code, fixed-line numbers begin with 9 and mobiles begin with 6.

Monaco mobile network prefixes
The prefix after +377 tells you which network issued the SIM — though number portability means it no longer guarantees the operator.
**Monaco Telecom** (dominant operator)
historically linked to Monaco's government; full mobile and fixed coverage across the principality.
Monaco time zone
Monaco observes Central European Time (CET, UTC+1) in winter, shifting to Central European Summer Time (CEST, UTC+2) during the EU-aligned daylight saving period — identical to France's own time zone, meaning no time adjustment is needed between the two countries despite their separate phone systems.
From the US East Coast, mid-morning through early afternoon ET reaches Monaco's business day, given the steady 6-hour gap. From the UK, add just an hour to your own clock — Monaco's working day runs almost identically to London's, just an hour ahead. From France, no time adjustment is needed at all.

Common mistakes when calling Monaco
Almost every failed international call is a formatting issue, not a network issue.
Assuming Monaco uses France's +33 code
it split away from France's own numbering plan on June 21, 1996 — Monaco has used its own +377 code ever since.
Skipping the international dialing format for France-Monaco calls
despite sharing a land border, calls between France and Monaco must be dialed in full international format on both sides.
Hunting for an area code
the numbering plan is flat — eight digits, no area code, no trunk prefix.
Assuming Monaco shares France's telecom regulator
Monaco maintains its own independent regulatory framework, separate from France's, reflecting its full sovereignty.
Expecting a different time zone from France
Monaco keeps the identical CET/CEST clock as France — no time adjustment needed between the two.
