Eastern Massachusetts has area codes 339, 351, 508, 617, 774, 781, 857, and 978. [8] Western Massachusetts has area code 413. [8]

Just three years ago, two new area codes were created in Massachusetts by splitting existing area codes in half. The 781 area code was carved out of the 617 code and the 978 area code was carved out of the 508 area code. With the addition of the four new overlay codes, Massachusetts will have nine area codes.
