Connecticut sits between New York City and Boston — Stamford's financial corridor, New Haven's Yale ecosystem, and Hartford's insurance industry make it a dense business market.
Connecticut's area codes split the state between its two economic identities — 203 for the southwest (Greenwich, Stamford, Bridgeport, New Haven), the hedge fund and financial corridor along I-95 and Metro-North, and 860/959 for Hartford, Waterbury, New Britain, New London, and the rest of the state — in the Eastern Time zone.
