New Caledonia at a glance
The numbers and facts you need before you dial.
What is the country code for New Caledonia?
New Caledonia answers to +687, a code all its own — not a slice of France's +33. Add it after your exit code and you reach any line in the territory. There is no trunk 0 and no area code to puzzle over: a Caledonian number is 6 digits, dialed straight after +687, and that's the whole story.
Though governed from Paris, New Caledonia carries its own E.164 assignment — +687 belongs to the territory alone and never overlaps with mainland +33.
All four mean the same thing — they connect your call to New Caledonia.
How to call New Caledonia from anywhere
One rule covers the whole archipelago: exit code + 687 + a 6-digit number. No region code, no stray 0 — what you see is what you dial.
Full example: +687 2049 XXX XXXX — drop the local leading 0 when calling from abroad.
New Caledonia phone number format explained
At 6 digits flat, a Caledonian number is among the most compact on the planet — no 0 in front, no area code bolted on. The opening digits do all the sorting, telling you at a glance whether you're ringing a landline or an OPT-NC Mobilis handset.
Teléfono fijo
6 digits, typically beginning 20–49 → e.g. 28 12 34. International: +687 28 12 34.
Móvil
6 digits, OPT-NC Mobilis ranges → e.g. 75 12 34. International: +687 75 12 34.

New Caledonia mobile network prefixes
The prefix after +687 tells you which network issued the SIM — though number portability means it no longer guarantees the operator.
OPT-NC (Office des Postes et Télécommunications de Nouvelle-Calédonie) — Mobilis
the sole mobile network. Mobile numbers fall in the 7x and newer 5x ranges (e.g. 73–79, 55–59). OPT-NC also operates all fixed lines and internet, holding a public-sector monopoly.
New Caledonia time zone
The territory runs on New Caledonia Time (NCT, UTC+11:00), fixed all year with no daylight saving. Sitting that far east, Nouméa greets the sun while Paris is still deep in the small hours — one of the planet's earliest clocks, hours ahead of Europe and a full day apart from the Americas.
With +11:00 working in your favour, Australia and New Zealand share almost your entire workday — dial them freely. France is the tricky one: catch it before lunch in Nouméa and you land in mainland late-afternoon, the only clean overlap of the day.

Common mistakes when calling New Caledonia
Casi todas las llamadas internacionales fallidas se deben a un problema de formato, no a un problema de red.
Padding the number out: a Caledonian line is 6 bare digits
no trunk 0, no city prefix, nothing to add before it.
Dialing it as if it were France: +687 is the territory's own code and shares nothing with mainland +33

Tips to reduce the cost of calling New Caledonia
Route over VoIP/SIP rather than carrier IDD
Pacific termination is among the costliest anywhere.
Hand contacts a +687 virtual number so their side of the call stays a local dial.
Time calls to Nouméa's working hours; the +11:00 gap makes a missed call an expensive redial.
Weigh wholesale +687 termination against the retail surcharges carriers stack on remote Pacific routes.
Why businesses get a New Caledonia virtual number
In a small market where everyone recognises a local line, a +687 caller ID does the quiet work of earning trust — and it sidesteps the steep Pacific tariffs a foreign number drags along.
Answered more often
a +687 Nouméa ID lands far better than a number arriving from the other side of the world.
Reads as one of their own
on a 270,000-person territory, a local line simply looks legitimate.
Inbound at island rates
terminate domestically instead of paying long-haul Pacific surcharges.
One queue for the lagoon
pull Nouméa and Greater Nouméa lines into a single team.
Plant a flag without a lease
serve the territory long before you'd ever open an office there.
A real, ringing line
a genuine +687 Nouméa number landing on your desk wherever it sits.

New Caledonia +687 — FAQ
If New Caledonia is French, why isn't it on +33?expand_more
Because the ITU assigned the territory its own E.164 code, +687. France's +33 will never reach a Caledonian line.
How short is a New Caledonia phone number, really?expand_more
Six digits — full stop. After +687 you dial just six, one of the most compact national formats anywhere.
Where are the area codes for Nouméa or Mont-Dore?expand_more
There aren't any. The whole territory runs a flat plan, so no city carries a separate prefix.
How do I tell a Mobilis mobile from a landline?expand_more
Read the first digit: mobiles fall in the 7-, 8- and 9-ranges (plus newer 5x blocks), while landlines sit in the 20–49 range.
Is there more than one mobile operator?expand_more
No — OPT-NC runs the sole Mobilis network and also holds the fixed-line and internet monopoly across the territory.
How far ahead is New Caledonia of Paris?expand_more
At UTC+11:00 with no daylight saving, Nouméa is typically 9 to 10 hours ahead of mainland France, depending on the European season.
Can someone outside the territory hold a +687 number?expand_more
Yes — MCM provisions +687 virtual numbers for businesses anywhere, no Caledonian residency or office needed.
My +687 call keeps failing — what's wrong?expand_more
Almost always an extra 0 or invented area code, or six digits stretched to seven. Strip it back to +687 plus exactly six.
