351 Area Code: Location, Time Zone & Phone Lookup - Page 2

Area code 351 is one of the original 86 area codes created in 1947. It covers the western suburbs of Boston, MA.The history of area code 351 is intertwined with the history of the Boston metropolitan area. The first phone exchange in the area was in Brookline, MA in 1877. The first area code was 617, which covered the entire Boston metropolitan area. In 1947, when area codes were introduced, area code 617 was split into two area codes: 617 and 857. Area code 351 covered the western suburbs of Boston, while 857 covered the eastern suburbs.

In 1984, area code 617 was split again, this time into three area codes: 617, 339, and 781. Area code 339 covered the southern suburbs of Boston, area code 781 covered the northern suburbs of Boston, and area code 351 continued to cover the western suburbs of Boston.

In 2001, area code 617 was combined with area code 857 to create area code 857. This left area code 351 as the only area code in the western suburbs of Boston.
