01 — Connecticut at a Glance

Connecticut, by the numbers.

Connecticut received area code 203 in 1947, covering the whole state for nearly fifty years.

The first split came in 1995: 860 took northern and eastern Connecticut, including Hartford, leaving 203 for the southwest — Bridgeport, New Haven, and Stamford.

203 got an overlay, 475, in 2009 to add capacity in the same southwestern territory.

The 860 region followed suit, gaining overlay 959 in 2014 to serve Hartford and eastern Connecticut.

Did you know?

Connecticut abolished county government back in 1960, yet its modern area code boundaries still roughly trace the old county lines, with 203/475 covering Fairfield and New Haven counties.
