Area code 508 was created on July 16, 1988, as a split from area code 617.[1] Prior to this split, 617 served the entire eastern two-thirds of Massachusetts from roughly the western end of Worcester County to Boston, The Cape and Islands, and the South Coast, while area code 413 (then as now) served all points west of the original 617 boundary. Permissive dialing of 617 and 508 continued until January 1, 1989.

On September 1, 1997, area code 508 was split, with area code 978 being assigned to the northern part of the service area. Area code 774 is an overlay code that was added to share the 508 service area, beginning on May 2, 2001. Since then, ten-digit local dialing is mandatory.

Some mobile telephone numbers assigned in the 1990s in communities in the former northern half of 508 (now the 978 area code) kept the area code after it split.[citation needed]

As of 2018, NPA 508/774 is projected to be exhausted by 2045.[2]
