Area code 309

Area code 309 serves Illinois, including Peoria, Bloomington and Rock Island (Central time). It has been in service since January 1, 1957 and shares its area with 861.

Numbers starting with 309 drew 1,049 reports to the FTC from Aug 14, 2026 to Nov 11, 2026 and 698 complaints to the FCC since November 2023. The number on your screen can be faked, so a 309 number proves nothing about where a call came from.

Phone companies holding 309 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.
