History of Area Code 475

Area code 475 was established in 2009 as an overlay for area code 203. The Connecticut Department of Public Utility Control approved the overlay after the older 203 area code began to run short on available phone numbers. The overlay took effect on December 12, 2009.

Area code 203 is one of the original area codes created in 1947, and it once covered all of Connecticut. In 1995, Connecticut split off area code 860 for most of the rest of the state, leaving 203 in southwestern Connecticut. The later addition of 475 let the region add more phone numbers without changing existing 203 numbers.
