Area code 413

Area code 413 is a telephone area code in the North American Numbering Plan (NANP) for the western third of Massachusetts. It is the largest numbering plan area in the Commonwealth, and extends from the New York state line eastward into Worcester County (only the towns of Hardwick and Warren), while excluding the Franklin County towns of Orange, New Salem, Warwick, and Wendell, which use the overlay of area codes 978 and 351. The most-populous city of area code 413 is Springfield. 413 also includes Chicopee, Northampton, Holyoke, Greenfield, and Amherst (LATA code 126).

History

Massachusetts was proposed to receive two area codes in the preliminary model of the North American Numbering Plan, the only state in New England to be split between multiple numbering plan areas. Area code 413 was intended for use in Pennsylvania.[1] However, when area codes were finalized, the eastern two-thirds of the state (including Boston and Worcester) was assigned 617, with 413 in the west.

Because of the low population density of western Massachusetts, 413 remained in its original configuration even as the eastern portion of the state went from one area code to four from 1988 to 1997. As a result, 413 is the only original numbering plan area of Massachusetts that still maintains its original boundaries, and is one of the few original area codes (not counting those that cover an entire state) that has never been split or overlaid. Even with the proliferation of cell phones and pagers, particularly in and around Springfield, it is currently projected to stay that way for the foreseeable future. The most recent exhaustion analysis does not provide an exhaust date for 413, meaning its exhaust date is more than 30 years in the future.[2]
