The 978 area code is designated for use by the North American Numbering Plan for the state of Massachusetts. The NANP is an area code system that includes the United States, Canada and several Caribbean nations. Each geographical area is assigned a unique three-digit area code based on the region. The 978 area code was established in 2001 and provides service to 30 counties in the eastern and northern parts of Massachusetts including Essex, Worcester, Middlesex and Hampshire.
The NANP system relies on a unified numbering format in order to provide correct routing of calls within and between each region. The first three digits of a phone number are the area code, and the following seven digits are the local numbers for the specific geographic area.
