AO — Angola

Angola is a Southern African nation on the Atlantic coast, known for its vast natural resources including oil, diamonds, and minerals. As a former Portuguese colony that gained independence in 1975, it is one of the largest Portuguese-speaking countries in Africa. Luanda, the capital, is one of the most expensive cities in Africa due to its oil-driven economy. The country spans 1.25 million square kilometers with diverse landscapes from tropical rainforests to arid deserts. For developers working with internationalization, the AO code maps to the pt-AO locale for Angolan Portuguese, which has subtle differences from Brazilian and European Portuguese. The Angolan Kwanza (AOA) uses specific formatting rules for currency display, and the +244 country calling code is necessary for any phone validation targeting Angolan users. Angola's growing tech scene and mobile-first population make proper localization increasingly important for applications serving the Lusophone African market.
