The Tonga Post National Home Addressing System is a national initiative to establish a structured, reliable and verifiable addressing framework across Tonga, with the full national building inventory across the country’s five island divisions already captured. Developed with technical support from the Universal Postal Union (UPU) and aligned with its S42 standard for postal address components and templates, the system aims to strengthen last-mile delivery for e-commerce and postal services while supporting emergency response, KYC processes and access to essential services.
