Why Macau 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.
Macau holds the alpha-2 code MO, the alpha-3 code MAC, the numeric code 446 and the internet domain .mo. It lists no capital city, because there is no seat of government to name. Calls are routed through the code +853.
