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.

What are the city and area codes in Monaco

Dialing tip: Monaco doesn’t have geographic “city area codes” the way larger countries do—these are service/prefix blocks that are part of the full national number. From abroad, dial +377 plus the full number (no leading 0 to drop).

Which mobile prefixes do mobile operators use in Monaco

Dialing tip: Monaco is commonly listed as not requiring mobile number portability, so prefixes are generally more stable as an “operator hint” than in many EU markets. Still, the safest approach for calling and messaging is to store numbers in +377 format

Monaco Telecom	3 (8-digit mobile), 44 (8-digit mobile), 451–459 (8-digit mobile), 46 (8-digit mobile), 6 (9-digit mobile ranges), 2 (12-digit M2M/IoT ranges)
