About the 312 area code
Area code 312 covers downtown Chicago, Illinois: the Loop, the Near North Side, and the central neighborhoods immediately around them. It is one of the original area codes assigned in 1947 and once covered all of Chicago and its suburbs. After the 773 split in 1996 it kept only the city's core, which is exactly why locals treat it as the downtown code. A 312 number reads as an established, central Chicago business, and the code carries real cachet in the city.
For a business, 312 is the number Chicago customers associate with the Loop, River North, and the West Loop. It signals a downtown presence without a downtown lease, and it tends to get answered by people who screen unfamiliar out-of-town numbers. Chicagoans also see 872, the overlay that shares the same central territory, and 773 in the neighborhoods as local, so a 312 number fits naturally on caller ID anywhere in the city.
