History of the 312 Area Code

312 area code is one of the most famous and oldest in the U.S. It was created in 1947 when phone numbers became localised nationwide. In its initial days, it covered all of Chicago and some parts of its neighbours. As the city population skyrocketed and the need for delicate area codes became apparent, 312 was separated to specifically use in Chicago, whereas 708, 773, and 872 were added to its neighbours.

Now, this area code covers Chicago's busiest downtown area, making it an excellent market for any business. Even though other area codes are being added nearby, the popularity of area code 312 is unmatched.
