Massachusetts is divided into five distinct numbering plan areas (NPAs) in the North American Numbering Plan (NANP), which are served by nine area codes,[7] organized as four overlay complexes and a single-area code NPA.
Eastern Massachusetts has area codes 339, 351, 508, 617, 774, 781, 857, and 978.[8] Western Massachusetts has area code 413.[8]
The numbering plan areas are organized into two local access and transport areas (LATAs): 126 comprises the western part, and 128 covers the central and eastern parts.[9]
