Area code 274

Area code 274 serves Wisconsin, including Green Bay, Manitowoc and Algoma (Central time). It has been in service since May 5, 2023 and shares its area with 920.

Numbers starting with 274 drew 30 reports to the FTC from Aug 14, 2026 to Nov 11, 2026 and 15 complaints to the FCC since November 2023. The number on your screen can be faked, so a 274 number proves nothing about where a call came from.

Phone companies holding 274 exchanges
