Lowell, MA is currently using an area code overlay in which area codes 351 and 978 serve the same geographic area. The area code overlay which is in use today was established in 2001 at which time area code 351 was created as an overlay of area code 978. Area code 978 was originally established in 1997. Ten digit dialing (area code + seven digit number) is necessary because two different homes in the same geographic area can have the same seven digit phone number but each would have a different area code.
In addition to Lowell, MA area codes 351 and 978 serve northeastern Massachusetts and the larger communities of Beverly, Chelmsford, Danvers, Fitchburg, Gardner, Gloucester, Haverhill, Lawrence, Leominster, Lowell, Methuen, Peabody, Salem and Wilimington, in addition to many smaller communities within the service area.
