History

The history of Massachusetts area codes is characterized by the need to accommodate the state's expanding telecommunications demands. Initially, Massachusetts had a single area code, 617, covering the entire state. However, as population and communication needs grew, additional area codes were introduced. In 1988, area code 508 was added to serve central and western Massachusetts, followed by area code 781 in 1997, which relieved congestion in the Boston metropolitan area. These changes reflect the evolving landscape of telecommunications in response to the state's growth and technological advancements.
