The area code 464 is located in Cicero, Illinois.
Area code 464 serves Cicero, Illinois, as an overlay to the long-standing 708 region in Chicago’s south and near‑west suburbs. Centered just west of Chicago’s city limits in Cook County, Cicero sits along key corridors like Ogden Avenue—part of historic Route 66—and near the site of the famed Western Electric Hawthorne Works. The 464 overlay helps add new phone numbers without changing existing 708 numbers, keeping local connections steady while supporting growth in one of the busiest suburban phone markets around Chicago. It’s a practical solution for residents, businesses, and anyone setting up a new line in Cicero and nearby communities.
Area code 464 was introduced in January 2022 as an overlay to 708 to meet rising demand for new phone numbers. With the overlay, 10‑digit dialing is required for local calls across the region, but current 708 numbers did not need to change. As regulators noted at launch: “10‑digit dialing is now mandatory across the 708/464 region” — Illinois Commerce Commission (2022). This setup expands numbering capacity while keeping everyday calling simple for Cicero and its neighbors.
Major communities covered by the 708/464 area include:
Cicero’s location makes area code 464 a key link between Chicago’s West Side and the inner-ring suburbs, with quick access to downtown, rail lines, and major highways. The 464 overlay builds on the area’s phone history: 708 dates to 1989 (split from 312) and has served these suburbs through decades of growth. Today, new phone numbers in Cicero may receive 464 or 708, but calling patterns and local service remain the same—just remember to dial all ten digits.
