Area code 904

Area code 904 serves Florida, including Jacksonville, Saint Johns and Fernandina Beach (Eastern time). It has been in service since July 11, 1965 and shares its area with 324.

Numbers starting with 904 drew 3,619 reports to the FTC from Aug 14, 2026 to Nov 11, 2026 and 1,097 complaints to the FCC since November 2023. The number on your screen can be faked, so a 904 number proves nothing about where a call came from.

Phone companies holding 904 exchanges
