Area Code 475 History and Coverage

Area code 475 was implemented as an overlay for existing Connecticut 203 numbering plan area in 2009. This is an example of implementation of a new code within an existing numbering plan area without splitting it into several smaller ones, i.e. not a split. An overlay increases numbering resources within a numbering plan area, while a split divides a territory into several code territories.

Code 203 was one of the first issued in the United States under North American Numbering Plan and was assigned to all Connecticut region in 1947. Later, in 1995, geographic split divided Connecticut between 203 and 860 codes; 203 remained for the lower part of Connecticut near the border with New York State and shores of Long Island Sound.

The introduction of 475 code was necessary for getting additional phone numbers in the 203 region; there was no redrawing of county and municipal boundaries. As a result, 475 covered the same geographical territory as 203, which is Fairfield County and New Haven County, and also neighboring parts of Litchfield County with the southern border along the coast of Long Island Sound.
