About Tonga Calling Code
Every country has a unique international dialing prefix; for Tonga it is +676. The ITU assigns these codes under recommendation E.164. Dial +676 after your country's exit code, then the local subscriber number. Tonga is in Oceania.
Every national network is identified by an E.164 country code. For Tonga that code is +676, allocated by the ITU and recognised by carriers worldwide — which is why a number saved as +676 plus the local digits stays dialable no matter which country you call from.
Where the +676 Calling Code Is Used
The country code +676 is assigned to Tonga, located in Polynesia, with the capital Nukuʻalofa. This code is part of the international telephony numbering plan and is used for all calls made to Tonga from outside the country.
A number displayed as +676 … is in international format: +676 replaces the domestic trunk prefix. From abroad, always drop any leading 0 of the area code and dial +676 + area code + subscriber number.
Calling codes starting with 6 are part of the ITU's regional numbering plan for the area around Tonga, in Polynesia. When saving Tonga numbers internationally, write +676 followed by the area code without its leading 0 — this format works from every country.
Tonga Phone Number Formats
Numbers in Tonga use the standard E.164 pattern — +676, then the area code, then the subscriber number. The same layout applies to landlines and mobile phones:
📱 Number Structure
- International format: +676 [area code] [subscriber number]
- From abroad: exit code + +676 + local number (drop the trunk prefix 0)
- Within Tonga: dial the local number directly
The digits you see on a Tonga business card are in national format and may begin with a trunk 0. That zero is a domestic signal only. Dial +676 first instead, then the rest of the number exactly as printed after the zero.
Time Zone in Tonga
Tonga runs on Pacific/Tongatapu, which is UTC+13:00 UTC. Schedule international calls accordingly — a convenient time for you may be very early or very late there.
Use the UTC offset (UTC+13:00) to plan calls to Tonga. For most international callers, the practical rule is: schedule business-hour calls to Nukuʻalofa during the overlap between your working day and theirs.
Daylight saving time can shift Tonga's clock by one hour in summer. For time-critical calls, confirm the current UTC offset rather than relying on the standard value.
