About the 781 area code
Massachusetts assigns area code 781 to a ring of communities around Boston, including Lynn, Waltham, and Medford, with the whole area inside the Eastern time zone.
Activated in 1997 as an overlay on top of code 617's area, it later gained 339 above its own territory. The resulting overlay complex means ten digits are required for every local call placed there.
Dialing note: 781 is part of an overlay complex with 339, so local calls in this area are dialed with all ten digits.
Numbering details on this page (service dates and overlay status) are checked against the NANPA numbering registry. Registry data as of 07/16/2026.
