Area code 645

Area code 645 serves Florida, including Miami, North Dade and Homestead (Eastern time). It has been in service since August 4, 2023 and shares its area with 305 and 786.

Numbers starting with 645 drew 500 reports to the FTC from Aug 14, 2026 to Nov 11, 2026 and 347 complaints to the FCC since November 2023. The number on your screen can be faked, so a 645 number proves nothing about where a call came from.

Phone companies holding 645 exchanges
