Area code 414

Area code 414 serves Wisconsin, including Milwaukee Zone 1, Milwaukee Zone 4 and Milwaukee Zone 5 (Central time). It has been in service since January 1, 1947.

Numbers starting with 414 drew 1,578 reports to the FTC from Aug 14, 2026 to Nov 11, 2026 and 657 complaints to the FCC since November 2023. The number on your screen can be faked, so a 414 number proves nothing about where a call came from.
