Massachusetts, by the numbers.
In 1947, Massachusetts split into two codes: 617 for Boston and the eastern two-thirds, and 413 for the western third.
508 split from 617 in 1988 for south-central and southeastern Massachusetts. In 1997, 781 split off for Boston's inner suburbs and 978 split from 508 for the northeast.
774 later overlaid 508. In 2001, three overlays arrived at once: 339 over 781, 351 over 978, and 857 over 617 — nine codes total with 413.
