Capital City to Country

About this calculator

This is a quick reference lookup: type in a capital city and get back the country it belongs to, along with practical details like the country's international dialing code and official currency. It covers the world's national capitals, including commonly confused or lesser-known ones (administrative vs. constitutional capitals, capitals that have changed in recent decades, and small or disputed-territory capitals).

Students studying world geography, trivia and quiz-night enthusiasts, travelers double-checking a destination's currency or phone code before a trip, and app or game developers building geography-based content all use lookups like this instead of digging through an atlas or encyclopedia entry by entry.
