Monaco's country calling code
The international telephone calling code for Monaco is +377. It appears in the standard international table of country calling codes as the code for Monaco.
Scope: +377 is a country-level code. It identifies Monaco as the destination country. It does not identify a city, district or individual line. The reference used here lists a single country code for Monaco and does not describe any internal area codes or subscriber number lengths.
Monaco has its own country code. Although it borders France, calls to Monaco use +377, not France's code.
How to dial a number in Monaco from abroad
An international call to Monaco has three parts, dialed in this order:
- 1. The international access prefix (exit code) for the country you are calling from.
- 2. Monaco's country code, 377.
- 3. The subscriber number in Monaco.

+377 [subscriber number]What depends on where you are calling from
The international access prefix belongs to the country or network you are calling from, not to Monaco. You did not state your location, so this guide cannot give a single definitive digit sequence. Check the exit code for your country or carrier, or use the plus-sign format on a mobile phone to avoid this step.
Checking the subscriber number
The source used for this guide confirms the country code only. It does not document Monaco's subscriber number lengths, its mobile and landline number ranges, or whether Monaco uses a domestic trunk prefix. If a Monaco number you have been given starts with a leading 0 or other domestic-only digit, confirm with the number's owner or your carrier whether that digit should be dropped after +377. As a general international rule, domestic trunk prefixes are not dialed after a country code.
