Why Niue has its own code
ISO 3166-1 assigns codes to territories as well as to sovereign states, because the codes are used for shipping, banking, internet domains, statistics and data exchange rather than as a statement about statehood. That is why this territory appears in country dropdowns, address forms and datasets alongside places many times its size.
Niue holds the alpha-2 code NU, the alpha-3 code NIU, the numeric code 570 and the internet domain .nu. The World Bank does not publish a separate population figure for it, so this page shows none rather than an estimate. Calls are routed through the code +683.
