Area code 248

Area code 248 serves Michigan, including Pontiac, Southfield and Royal Oak (Eastern time). It has been in service since May 10, 1997 and shares its area with 947.

Numbers starting with 248 drew 1,305 reports to the FTC from Aug 14, 2026 to Nov 11, 2026 and 627 complaints to the FCC since November 2023. The number on your screen can be faked, so a 248 number proves nothing about where a call came from.

Phone companies holding 248 exchanges
