History of Area Code 464

Area code 464 was approved as an overlay for area code 708 in Illinois. The Illinois Commerce Commission approved the 464 overlay in 2021 after forecasts showed that new phone numbers in the 708 area would run short. An overlay means 464 was added to the same geographic area instead of splitting the region into smaller parts.

Area code 708 has served Chicago's inner-ring suburbs since 1989, when it was created in a split from area code 312. The 464 overlay was scheduled to begin service in 2022. Because 464 overlays 708, customers in the area must use 10-digit dialing for local calls.
