Tonga Country Code

How do I dial mobiles vs landlines in Tonga

Tonga’s country calling code is +676. If you’re calling Tonga from abroad, dial your international exit code (or + on a smartphone), then 676, then the full local number. Tonga’s numbering plan is short and consistent: landlines are typically 5 digits total (a 2-digit area code plus a 3-digit subscriber number), so they usually look like +676 20 XXX. Mobile numbers are typically 7 digits total (a 3-digit mobile prefix plus a 4-digit subscriber number), so they commonly look like +676 840 XXXX. If you’re calling out of Tonga to another country, the international access prefix is 00. 

Within Tonga, people generally dial the number exactly as written (there’s no “add a 0” trunk rule you have to remember). The key practical difference is simply the length and prefix: fixed lines use the two-digit geographic codes (like 20–28 in Nukuʻalofa), while mobiles use three-digit operator ranges (like 84x for Digicel). For best reliability (roaming, WhatsApp/SMS verification, saved contacts), publish and store numbers in E.164 format as +676 plus the full number.
