About the 312 area code
Since 1947, Chicago has been reached through area code 312, one of the original assignments, which also lists Cicero and Schaumburg within its Illinois coverage. Central time applies here.
Three newer codes trace to its territory. 708 and 773 were created out of it, and 872 was added as an overlay that continues to share the city's ground, so ten-digit dialing covers local calls in the city.
Dialing note: 312 is part of an overlay complex with 872, so local calls in this area are dialed with all ten digits.
Numbering details on this page (service dates and overlay status) are checked against the NANPA numbering registry. Registry data as of 10/08/2026.
