Area code 351

Area code 351 serves Massachusetts, including Acton, Lowell and Danvers (Eastern time). It has been in service since May 2, 2001 and shares its area with 978.

Numbers starting with 351 drew 577 reports to the FTC from Aug 14, 2026 to Nov 11, 2026 and 214 complaints to the FCC since November 2023. The number on your screen can be faked, so a 351 number proves nothing about where a call came from.

Phone companies holding 351 exchanges

Each exchange (the three digits after the area code) is assigned to one carrier. 98% of these exchanges are pooled: their numbers are handed out in blocks of 1,000 to other carriers, so the holder below is not always the company serving a given number.
