KN — Saint Kitts and Nevis

Saint Kitts and Nevis is a dual-island Caribbean nation, the smallest sovereign state in the Americas by both area and population. Basseterre, on Saint Kitts, is the capital. The federation pioneered the Citizenship by Investment program in 1984, which has since been adopted by many nations. The East Caribbean Dollar (XCD) is the currency. For developers, the KN country code and .kn domain identify this small federation. The +1-869 follows the North American Numbering Plan. The en-KN locale handles local English. Saint Kitts and Nevis's Citizenship by Investment program means its passport and nationality codes appear in identity verification systems more frequently than its population size might suggest. The federation structure (two islands that can theoretically separate) creates interesting constitutional data edge cases. Despite its tiny size, the country's financial services and investment programs give it outsized importance in fintech and identity verification applications.
