Geographic Coverage
The 413 area code spans the four westernmost counties of Massachusetts – Hampden, Hampshire, Franklin, and Berkshire. It includes the Springfield metro area (Springfield, Chicopee, Holyoke, Westfield), the Five College region around Amherst and Northampton, the Franklin County seat of Greenfield, and the Berkshire city of Pittsfield. It borders Connecticut to the south, New York to the west, and Vermont and New Hampshire to the north.
Time Zone
The 413 area code observes Eastern Time (ET). Clocks follow Eastern Standard Time (UTC−5) in winter and shift to Eastern Daylight Time (UTC−4) from mid-March through early November. If you are coordinating a call from the West Coast, remember that this region is three hours ahead of Pacific Time, so a 9:00 AM call in California reaches a 413 number at 12:00 PM local time.
Tip: Business hours across the 413 region generally run 9:00 AM to 5:00 PM Eastern Time, Monday through Friday.
How to Dial a 413 Number
Area code 413 is not part of an overlay, so it has traditionally allowed 7-digit local dialing. However, 10-digit dialing is now the recommended nationwide standard, and dialing the full 10-digit number (413 + the line number) always works reliably. For international callers, dial your country’s exit code, then +1 (the North American country code), then 413, followed by the seven-digit local number.
Scam Alerts for the 413 Area Code

History and Economy of the 413 Region
The 413 area code is one of the original 86 area codes established in 1947 when the North American Numbering Plan was first created, making it one of the oldest continuously used codes in the country. Remarkably, western Massachusetts has never needed an overlay or a split – 413 still serves the entire region on its own more than seventy-five years later. The area’s economy blends education, healthcare, manufacturing, and tourism. The Pioneer Valley is home to the Five Colleges – the University of Massachusetts Amherst, Amherst College, Smith College, Mount Holyoke College, and Hampshire College – which together make higher education one of the region’s largest employers. Springfield, the third-largest city in Massachusetts, anchors the southern end as a hub for healthcare, finance, and the birthplace of basketball. To the west, the scenic Berkshires draw visitors year-round to destinations such as Tanglewood, MASS MoCA, and Pittsfield, sustaining a vibrant cultural-tourism economy.
