Origin Story
Area code 312 was one of the original 86 area codes established in 1947 for the North American Numbering Plan. It was assigned to the Chicago metropolitan area due to the city's high population density. For decades, 312 served the entire city and its suburbs. In 1996, a split created area code 773 for the city outside the downtown core, leaving 312 to serve the central business district and immediate downtown neighborhoods. In 2009, overlay area code 872 was introduced to provide additional numbering capacity for the same geographic area. Today, 312 remains a prestigious and iconic code, representing the historic and economic heart of Chicago.
