Area code 351 is the overlay for the 978 code, covering northeastern Massachusetts including the old textile cities of Lowell and Lawrence and the historic North Shore fishing communities. The region is also home to major technology and biotechnology employers along Route 128. The overlay was added in 2001.
Across Massachusetts, the 351 area code serves roughly 1 million residents in 4 communities — including Lowell, Lawrence, Haverhill, among others. Numbers in the 351 zone keep Easterntime, so a local line rings during your customers' business hours and shows a familiar MA caller ID on every outbound call.
351 was first introduced in 2001 as an overlay of the 978 area code, adding fresh numbering capacity to the same region without forcing anyone to change an existing number. Because an overlay shares geography with another code, ten-digit dialing is standard throughout the area. It remains an active overlay code today.
