New Caledonia Country Code

How do I dial mobiles vs landlines in New Caledonia

New Caledonia’s country calling code is +687, and it uses a closed 6-digit numbering plan. That means local numbers are typically written in pairs (e.g., XX XX XX) and you dial all 6 digits within New Caledonia—there’s no national trunk prefix (no leading 0) to add or remove. When calling from abroad, dial your international exit code (or use +), then 687, then the 6-digit number, for example: +687 20 XX XX or +687 75 XX XX. If you’re calling out of New Caledonia, the international access prefix is commonly 00 (or simply use + on mobiles). 

The difference between landlines and mobiles is mostly the starting digits, not a city “area code” system. Fixed (PSTN) lines commonly start with prefixes like 20, 23–29, 30–35, and 41–47, while mobile numbers are allocated in ranges such as 70–79, 80–87, and 89–99 (and additional mobile series exist). As of 15 January 2025, OPT-NC also announced new mobile number series 55XXXX–59XXXX for its Mobilis services, so you may increasingly see mobiles beginning with 55–59 as well. For clean contact storage across travel and messaging apps, save numbers as +687 plus the full 6 digits.
