History of Area Code 351
Area code 351 entered service on May 2, 2001, as an overlay for area code 978. Area code 978 had been created in 1997 when the older 508 area code was split to serve growing northeastern and north-central Massachusetts.
The 351 overlay did not divide the 978 region into separate geographic sections. Existing customers kept their 978 numbers, while new customers could receive numbers with either 978 or 351. The overlay provided additional phone numbers as demand grew from households, businesses, wireless services, and other communications providers.
