Tonga Address Format
Addresses go from smallest unit to largest: recipient, street address or P.O. Box number, town/island, then TONGA. Because there are no postal codes, the town name (and island for outer islands such as Vava'u or Ha'apai) is the key routing element. Limited public documentation on formal street addressing; P.O. Box addressing dominates.
