text: Area codes 508 and 774 are telephone area codes in the North American Numbering Plan (NANP) for the U.S. state of Massachusetts. The numbering plan area comprises south-central and most of southeastern Massachusetts (LATA 128). It includes Worcester, Outer south and southwest Greater Boston (such as the MetroWest region), as well as Fall River, New Bedford, Cape Cod, Martha's Vineyard, and Nantucket.
  History
  Massachusetts was originally divided into two numbering plan areas, when AT&T published the configuration of the first nationwide telephone numbering plan for Operator Toll Dialing in 1947. Area code 617 was assigned to the eastern two-thirds of Massachusetts from roughly the western end of Worcester County to Boston, The Cape and Islands, and the South Coast, while the western part received area code 413.
