Area code 920

Area code 920 serves Wisconsin, including Green Bay, Appleton and Oshkosh (Central time). It has been in service since July 26, 1997 and shares its area with 274.

Numbers starting with 920 drew 1,953 reports to the FTC from Aug 14, 2026 to Nov 11, 2026 and 686 complaints to the FCC since November 2023. The number on your screen can be faked, so a 920 number proves nothing about where a call came from.

Phone companies holding 920 exchanges

Each exchange (the three digits after the area code) is assigned to one carrier. 77% of these exchanges are pooled: their numbers are handed out in blocks of 1,000 to other carriers, so the holder below is not always the company serving a given number.
