Area code 508

Area code 508 serves Massachusetts, including Worcester, Framingham and Brockton (Eastern time). It has been in service since July 16, 1988 and shares its area with 774.

Numbers starting with 508 drew 1,017 reports to the FTC from Aug 14, 2026 to Nov 11, 2026 and 1,035 complaints to the FCC since November 2023. The number on your screen can be faked, so a 508 number proves nothing about where a call came from.

Phone companies holding 508 exchanges

Each exchange (the three digits after the area code) is assigned to one carrier. 59% of these exchanges are pooled: their numbers are handed out in blocks of 1,000 to other carriers, so the holder below is not always the company serving a given number.
