CL — Chile

Chile is a long, narrow South American country stretching 4,300 km along the Pacific coast from Peru to the southern tip of the continent. Santiago, the capital, is the cultural and financial center. Chile has the most advanced economy in South America and hosts the world's most powerful astronomical observatories in the Atacama Desert. The Chilean Peso (CLP) has no subdivision — all amounts are whole numbers with no decimal places. For developers, the CL country code maps to the es-CL locale for Chilean Spanish, which has distinctive slang and conventions. The .cl domain is well-established, and +56 is the dialing code. Chile's RUT (Rol Único Tributario) tax identification system uses a unique check-digit algorithm (modulus 11) that applications must validate. The CLP's lack of decimal places simplifies some formatting but applications must not display centavos. Chile's strong tech startup ecosystem and high internet penetration make it a key South American market for digital products.
