Geographic Coverage & Major Cities
Area code 464 covers the southern and near-west suburbs of Chicago in Cook County. Because it is an overlay, it shares the identical footprint of the 708 area code rather than covering a separate zone.
- Cicero & Berwyn – dense near-west suburbs bordering the city
- Oak Park – a historic community just west of Chicago
- Oak Lawn & Orland Park – major southwest suburbs
- Tinley Park & surrounding towns – established south suburban communities
As the newest code over the south suburbs, 464 numbers are typically assigned to lines set up after the original 708 numbers grew scarce.
A Brief History of Area Code 464
Area code 464 was activated in 2023 as an all-services overlay on the 708 region, making it one of the newest area codes in Illinois. The 708 code dates to 1989 as the first suburban Chicago code. An overlay adds a second area code across the same geographic area, so existing 708 customers keep their numbers while new lines can be assigned either code, under mandatory 10-digit dialing.
Time Zone & Best Time to Call
Numbers in the 464 area code use Central Time (CT). The region observes Daylight Saving Time, shifting from CST (UTC-6) to CDT (UTC-5) between March and November each year.
