Where 312 is, the cities it covers, its time zone and its overlay. And how to get a 312 number your AI agent answers.
One of the original 1947 area codes, 312 first served almost all of the Chicago area in Illinois. The suburbs moved to 708 in 1989 and the rest of the city outside downtown to 773 in 1996. Since 2009 the 872 overlay has covered both 312 and 773, so local calls need all ten digits.
