Find any 475- phone number in Connecticut
The Connecticut area code 475 is located within the North American Numbering Plan, also known as NANP, as an overlay to the 203/860 area code. This means that within Connecticut, both the 203/860 and 475 area codes are used to designate local telephone numbers. In addition to Connecticut, the NANP includes Canada, the Bahamas, some Caribbean nations, and the U.S. territories.
The particular area code and the regional boundaries assigned to it is determined by the US Federal Communications Commission (FCC). Connecticut became the first NANP state to introduce an overlay in 2009, making the numbers that once corresponded to the 203/860 area code available to the 475 code. The 475 area code is designed to alleviate the issue of having a limited number of telephone numbers in the 203/860 area code, which consequently caused consumers to be unable to acquire a telephone number.
