Area code 931

Area code 931 serves Tennessee, including Clarksville, Cookeville and Columbia (Eastern and Central time). It has been in service since September 15, 1997.

Numbers starting with 931 drew 1,831 reports to the FTC from Aug 14, 2026 to Nov 11, 2026 and 421 complaints to the FCC since November 2023. The number on your screen can be faked, so a 931 number proves nothing about where a call came from.

Phone companies holding 931 exchanges

Each exchange (the three digits after the area code) is assigned to one carrier. 73% 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.
