CO — Colombia

Colombia is a country in the northwest corner of South America with coastlines on both the Caribbean Sea and the Pacific Ocean. Bogotá, the capital, sits at 2,640 meters elevation in the Andes. Colombia is the world's leading emerald producer and a major coffee exporter. The Colombian Peso (COP) operates with large denomination values, meaning everyday prices are in thousands. For developers, the CO country code is notable because the .co ccTLD has been brilliantly marketed as a generic alternative to .com, making it one of the most commercially successful ccTLDs worldwide (used by companies like t.co, g.co, and many startups). The es-CO locale handles Colombian Spanish. The +57 dialing code serves Colombia's growing digital market. Colombia's NIT tax identification system requires specific validation. The .co domain's global success means developers frequently encounter it as both a Colombian ccTLD and a generic commercial domain, requiring context to determine the user's actual location.
