The 857 area code covers Boston, Cambridge, Somerville and more in Massachusetts. Provision a local 857 number in minutes.
Area code 857 is the overlay for the 617 code, covering the Boston metro area and Cambridge. As Boston became one of the world's leading hubs for biotechnology, finance, and education, demand for phone numbers grew dramatically. The overlay was introduced in 2001 and both codes now require 10-digit dialing throughout greater Boston.
Across Massachusetts, the 857 area code serves roughly 900,000 residents in 4 communities — including Boston, Cambridge, Somerville, among others. Numbers in the 857 zone keep Easterntime, so a local line rings during your customers' business hours and shows a familiar MA caller ID on every outbound call.
857 was first introduced in 2001 as an overlay of the 617 area code, adding fresh numbering capacity to the same region without forcing anyone to change an existing number. Because an overlay shares geography with another code, ten-digit dialing is standard throughout the area. It remains an active overlay code today.
