Area code 464

Area code 464 serves Illinois, including Oak Forest South, Forest and La Grange (Central time). It has been in service since January 21, 2022 and shares its area with 708.

Numbers starting with 464 drew 443 reports to the FTC from Aug 14, 2026 to Nov 11, 2026 and 189 complaints to the FCC since November 2023. The number on your screen can be faked, so a 464 number proves nothing about where a call came from.

Phone companies holding 464 exchanges

Each exchange (the three digits after the area code) is assigned to one carrier. 100% 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.
