Case Study: Tonga Post improves national postal delivery across 36 islands with what3words

Tonga adopts what3words as national postal addressing system

Tonga Post, the official postal service for the Kingdom of Tonga, faced major delivery challenges across 36 inhabited islands spread over 700,000 square kilometres, with few named streets and many undelivered parcels. To improve national infrastructure and support growing international mail and e-commerce demand, Tonga Post adopted what3words’ 3 word address system.

what3words enabled Tonga Post to give every location in Tonga an instant address, making deliveries more practical, user-friendly, and cost and time efficient. The rollout allowed postal services to expand beyond centralised PO Boxes, reduce undelivered mail, and support new revenue from inbound parcels and e-commerce, helping Tonga Post serve customers across the islands more effectively.
