Area code 203 covers Fairfield County and New Haven County in southwestern Connecticut — Stamford, Bridgeport, New Haven, Greenwich, Norwalk, and Danbury. Fairfield County is one of the most affluent counties in the US: Greenwich is the global headquarters of the hedge fund industry, with more assets under management per square mile than any location outside Manhattan. Stamford hosts the regional headquarters of major financial institutions, media companies, and professional services firms. UBS, RBS, and Charter Communications all maintain significant 203 operations. New Haven's Yale University and the medical corridor it anchors add a substantial research and healthcare dimension to the already financial-services-heavy 203 economy.
From Bridgeport to Norwalk 203 covers the New England region of Connecticut.
