Monaco Country Code

How do I dial mobiles vs landlines in Monaco

Monaco’s country calling code is +377. Monaco doesn’t use a national trunk prefix (no leading “0”), so the simplest rule is: dial the national number as-is inside Monaco, and from abroad dial +377 followed by the national number. Monaco uses a compact numbering plan: fixed-line numbers are typically 8 digits and commonly start with 9, while mobile services use dedicated mobile prefixes (including 3, 44, 45x, 46, and some 9-digit mobile ranges starting with 6). 

One practical nuance: although Monaco sits next to France, calls between France and Monaco must be dialed in international format (e.g., +377 …), not as a domestic French call. From inside Monaco, the international dialing prefix is commonly 00 (or just use + on a mobile). For reliable contact storage across devices and travel, save every Monegasque number in E.164 format like +377 …—this avoids country/format confusion, especially for mobile ranges that can be 8 or 9 digits depending on the prefix block.
