Country by Capital City

About this calculator

This lookup matches a capital city to its country using standard ISO country data, then surfaces two related facts that usually travel together with geography: the country's official currency and its international dialing code — details that are easy to mix up between neighboring or historically linked countries (Vienna and Bratislava, for instance, sit less than 60 km apart but belong to entirely different currency and calling-code systems).

Reference tools like this trace back to standard geographic databases used in atlases, almanacs, and now digital gazetteers, which pair a capital with its country's key identifying facts precisely because capital cities are the most commonly known landmark for a country, more so than any other single city.

Students studying world geography, trivia and quiz writers double-checking facts, travelers researching currency and calling codes before a trip, and journalists fact-checking a dateline all use a lookup like this instead of committing 190-plus capital-country pairs to memory.
