Illinois was assigned area code 312 for Chicago and 618 for the rest of the state in 1947. Chicago's explosive growth drove 708 to be split off for the suburbs in 1989, then 847 for the northern suburbs and 630 for the western suburbs in 1996.
Chicago proper retained 312 for the downtown core while adding overlay 872. The surrounding metro now spans eight area codes — one of the densest concentrations in the Midwest.
Chicago's 312 is one of the original 1947 NANP codes and remains the prestige downtown prefix — businesses actively seek 312 numbers over overlay 872 because of its decades-long association with the Loop and the city's financial district.
