978 Area Code: Lowell, Massachusetts

Northern and central Massachusetts outside the immediate Boston metro is served by the 978 area code, with Lowell as the primary city. Lowell sits along the Merrimack River, on a stretch of waterfall-driven river that gave the city its origin as one of the first planned industrial cities in the country — the rebuilt nineteenth-century mill complexes still organize the city's downtown. The 978 footprint reaches through Lawrence, Haverhill, Andover, Fitchburg, and the surrounding Merrimack Valley and north-central Massachusetts communities.

Records linked to 978 numbers in the directory often include Boston, Quincy, Springfield, and Worcester — Massachusetts cities outside the 978 footprint. The pattern reflects standard public-record dynamics, with phone numbers porting across Massachusetts and addresses linked across multiple cities. The directory currently documents 547 distinct prefixes within 978 in detail, a working subset of the prefix population the code carries.

Lowell's home values come in above the US median, in line with broader eastern Massachusetts pricing pressure. Median household income runs close to the national reading, the city's median age sits a few years under the US figure, and population places Lowell among the larger Massachusetts cities — substantial enough to anchor a regional economy organized around healthcare, technology, the surrounding university campuses, and the long-running redevelopment of the historic mill district. The broader 978 footprint reflects a mix of mid-sized cities and the surrounding north-central Massachusetts towns.
