Area code 608

Area code 608 serves Wisconsin, including Madison, Janesville and La Crosse (Central time). It has been in service since January 1, 1955 and shares its area with 353.

Numbers starting with 608 drew 1,758 reports to the FTC from Aug 14, 2026 to Nov 11, 2026 and 984 complaints to the FCC since November 2023. The number on your screen can be faked, so a 608 number proves nothing about where a call came from.

Phone companies holding 608 exchanges
