									Area codes 203 and 475
From Wikipedia, the free encyclopedia

Area code 203 is a North American telephone area code that covers the
southwestern part of Connecticut, and is overlain with area code 475.
The area codes stretch from Connecticut's western border, along its
southern coast, to beyond the city of New Haven, and ends just south of
Hartford. (The rest of Connecticut is served by the 860 area code, which
will be overlain with 959 at an undisclosed date.) The region
encompassed by 203 and 475 roughly corresponds to the part of
Connecticut belonging to metro NYC. Prior to August 28, 1995 (when the
split with 860 took effect), area code 203 encompassed all of

Area code overlay
The Connecticut Department of Public Utility Control    , in August 1999, proposed an area code overlay for the 203 area
code.[3] Area code 475 went into effect on December 12, 2009. Even though area code 475 overlays only 203, all callers in
Connecticut (including those in area code 860) had to dial all calls with ten digits, effective November 14, 2009 [4] ; this is
because when needed, an overlay of area code 959 on area code 860 will be implemented.
The first range of available numbers made available in Connecticut's third area code was (475) 882-4xxx, in the Huntington
section of Shelton.
