Area code 978

Area code 978 is a telephone area code in the North American Numbering Plan for the north-central and northeastern regions of the Commonwealth of Massachusetts. It was created in 1997 as a split from the original Area code 508, which had served the entire region outside of the Greater Boston metropolitan area. The 978 region encompasses historic cities, suburban communities, and rural towns, forming a significant part of the state's cultural and economic landscape outside its major urban centers.

History and establishment

The need for area code 978 arose from the rapid proliferation of fax machines, cell phones, and pagers in the 1990s, which exhausted the numbering pool of its parent, Area code 508. The North American Numbering Plan Administrator approved the split, which was implemented on September 1, 1997. The creation of 978 was part of a series of telecommunications changes in Massachusetts that also included the introduction of Area code 781 and Area code 617. This geographic split assigned the northern and western portions of the old 508 territory to the new 978 code, while the southern portion, including cities like New Bedford and Fall River, retained the 508 designation.

Service area and communities

Area code 978 serves a diverse region that includes major urban centers, historic mill cities, and extensive suburban and rural areas. Key cities within its boundaries include Lowell, a former industrial powerhouse and home to the University of Massachusetts Lowell; Lawrence; and Haverhill. It also covers the historic North Shore communities of Gloucester and Salem, famed for its Salem witch trials heritage. The code extends westward to include the growing technology corridor around Acton and Billerica, and north to the New Hampshire border, serving towns like Groton and Pepperell.

Overlay area codes and relief planning

Due to continued demand for telephone numbers, particularly for mobile devices and internet services, area code 978 was placed under an overlay complex with the new Area code 351. This overlay was approved by the Massachusetts Department of Telecommunications and Cable and the Federal Communications Commission to avoid a geographically disruptive split. The 351 code was activated on April 2, 2018, and serves the same geographic region as 978. This overlay plan followed a pattern used elsewhere in the state, such as with Area code 857 overlaid on Area code 617, to extend the life of existing numbering resources.

Dialing procedures and implementation

With the implementation of the 351 overlay, mandatory ten-digit dialing (area code + seven-digit number) became required for all local calls within the 978/351 region. This change was phased in, with a permissive dialing period allowing seven-digit calls before the official switchover. The overlay ensured that all existing customers in cities like Fitchburg and Andover retained their 978 numbers, while new numbers could be assigned from either the 978 or 351 prefixes. This procedure is consistent with NANPA standards deployed in other overlay areas across the United States.

In popular culture

The region covered by area code 978 has been featured in numerous literary and cinematic works, often drawing on its rich historical and coastal settings. Author Jack Kerouac, a native of Lowell, set much of his work in the area. The city of Salem is a frequent backdrop for films and television shows about the Salem witch trials, such as Hocus Pocus. Furthermore, the coastal landscapes of Cape Ann, including Rockport and Gloucester, have been featured in films like The Perfect Storm, which dramatized the story of the fishing vessel Andrea Gail.
