Connecticut State in United States
Description
Connecticut, one of the original 13 colonies, offers a charming mix of colonial history, Ivy League prestige, and coastal beauty. With picturesque towns, historic maritime centers like Mystic, and proximity to New York City, Connecticut blends the serenity of New England with metropolitan sophistication. The state is also a hub for insurance, education, and biotech innovation.

The state originally had just one area code — 203, assigned in 1947. Due to rising demand in the Fairfield and New Haven regions, 860 was added in 1995 to cover the rest of the state. To support continued growth, overlays 475 (for 203) and 959 (for 860) were introduced in the 2000s. Today, Connecticut area codes reflect a balance between dense coastal urbanization and rural interior communities, keeping the state connected across business, healthcare, and academic institutions.
