Area code 413 covers western Massachusetts, including cities like Springfield, Pittsfield, and Northampton. It was established in 1947 and remains the only area code to serve this region, which includes the Berkshires and parts of the Connecticut River Valley. Known for its scenic beauty, historic towns, and colleges like Amherst and Williams, the 413 region is culturally rich and geographically distinct from eastern Massachusetts. Seven-digit dialing remains common. Area code 413 is a marker of rural charm, intellectual heritage, and regional pride in a part of New England that values history, nature, and community.
