Area code 773

From Wikipedia, the free encyclopedia

Area code 773 went into effect in the northern, western and southern neighborhoods of the city of Chicago, Illinois on 12 October 1996.^[1] Originally, the entire city and much of northeastern Illinois were in area code 312. Then, in 1989, area code 708 was created for the suburbs, leaving a rump 312. Eventually, the city itself was split between 312 in the downtown/Loop areas and 773 in the rest of the city. On August 10, 2009, the Illinois Commerce Commission announced that area code 872 will overlay area codes 312 and 773, and will enter service on November 7, 2009.^[2]
