312 Area Code

It comes as no surprise that Chicago has three major area codes serving its huge population. The area code 312 is one of the original 86 area codes created by AT&T and the Bell System in 1947. 312 was created to serve the Chicago metropolitan area, which includes Cook County and the city of Chicago, before it was split in 1996 into 773.

872 Area Code

It wasn't until 2009 that 872 was created and it currently overlays 312 and 773. The area codes 312 and 773 are integral aspects of Chicago communities and communication channels.
