Questions about this area code
Where is area code 978?
978 is a Massachusetts area code covering Lawrence, Lowell and Billerica. NANPA's report lists 775 exchanges in use across 58 rate centres.
Is 978 a mobile or a landline area code?
Both. An area code doesn't decide the line type: mobile, landline and VoIP numbers all use 978, and numbers move between carriers. Check the number itself to see what it is today.
Which area codes overlay 978?
351 has numbers in at least half of the same places as 978, so a new number there can get any of these area codes.
Can you tell me who owns a 978 number?
No. NumberLookup shows whether a number is valid, its line type, its carrier and its region, never the person or business behind it.
Source: NANPA's public central office code and thousands-block reports, refreshed weekly. Carriers are the ones the numbers were assigned to, not necessarily today's, and never the person who uses a number.
