Area code 660

Area code 660 serves Missouri, including Sedalia, Kirksville and Warrensburg (Central time). It has been in service since October 12, 1997.

Numbers starting with 660 drew 780 reports to the FTC from Aug 14, 2026 to Nov 11, 2026 and 177 complaints to the FCC since November 2023. The number on your screen can be faked, so a 660 number proves nothing about where a call came from.

Phone companies holding 660 exchanges

Each exchange (the three digits after the area code) is assigned to one carrier. 79% 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.
