Area code 413とは 意味・読み方・使い方

Area code 413 is the area code for western Massachusetts. It is the largest area code by land area covered in the Commonwealth, an original area code for Massachusetts (with 617), and extends from the New York border to the border of Worcester County, though it includes two towns within that county, Hardwick and Warren, while excluding several eastern Franklin County towns, Orange, New Salem, Warwick and Wendell and covering from border to border north to south. Although western Massachusetts has no overlay area code, it requires 10 digit-dialing for calls outside of designated calling areas.
