Area code 413

Area code 413 (LATA code 126) 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 Great Barrington, Greenfield, North Adams, Northampton and Pittsfield.

History

In the preliminary model of the North American Numbering Plan, Massachusetts was allotted two area codes, the only state in New England to be split between multiple numbering plan areas. Area code 413 was intended for use in Pennsylvania.[1] When the area code map was finalized, Massachusetts remained split between two numbering plan areas. However, 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 despite the proliferation of cell phones and pagers, particularly in and around Springfield. The projected exhaust date for 413 is 2041.[2]
