203 Area Code

Area code 203 is a North American telephone area code that is allotted to the southwestern portion of Connecticut and is covered with area code 475. The numbering plan area (NPA) 203 basically covered the whole state of Connecticut when the North American Numbering Plan was founded in 1947. Today the numbering plan area stretches from Connecticut’s western border, along its southern coast, to Madison, and north to Meriden. The area surrounded by 203 and 475 is mostly coextensive with the Connecticut side of the New York city area.
