[edit] History

Area code 617 once covered the entire eastern half of Massachusetts, and was coextensive with the Eastern Massachusetts LATA #128. It now covers only the city of Boston and some immediate suburbs. When the demand for phone numbers in the Boston area skyrocketed due to rising use of fax machines, pagers, alarm systems and dial-up computer service providers, area code 508 split off in 1988, with the immediate vicinity of the city (roughly inside of Route 128) keeping the code 617. Area code 617 split again in 1997, with area code 781 assigned to areas more distant from Boston. Subsequently, area code 857 was added as an overlay to parts of area code 617.

[edit] Trivia

In an odd coincidence, and has been noted by national commentators, the Boston Celtics, the local professional basketball team, won their 17th NBA title on 6/17/2008, playing in front of their home crowd within the 617 area code.^[1]
