Area codes 847 (northern suburbs) and 630 (western suburbs) were created from a split of suburban area code 708 in 1996. Shortly after in 1996, area code 773 was created for the residential parts of the city of Chicago, while downtown kept area code 312.
As a result, the city of Chicago was divided into two area codes, 312 and 773. Rather than divide the city by a north–south area code, the central business district retained the 312 area code, while the remainder of the city took the new 773 code. In 2002, the 847 area code was supplemented with the overlay area code 224.
