Detailed Country Guide
Overview and identity
Tonga, officially listed here as Kingdom of Tonga, is structured as a practical country reference guide for users searching country facts, maps, flags, codes, and daily-use data. The page should make Tonga, TO, TON, the flag, the official name, and the country slug easy to confirm because users often land on country pages while checking identifiers for forms, travel, education, or data products. Tonga is grouped under Oceania, more specifically Polynesia, with Oceania shown as the continent context.

Capital and urban network

Including cities alongside country-level facts helps the guide answer searches such as largest cities in Tonga, capital of Tonga, and major urban areas in Tonga. This is useful because many users compare the official capital with the largest business, transport, or population centers.

How to use this profile
This Tonga profile is designed to be scanned in layers: first the name, official name, flag, capital, population, area, and density; then identity, geography, cities, governance, memberships, formats, connectivity, currency, languages, transport, and references. That structure supports both human readers and product workflows where users need to verify a phone code, compare cities, inspect fiscal dates, check postal formats, review memberships, or open a map reference without searching across multiple pages.
