What Is the 312 Area Code?

The 312 area code is one of the oldest telephone codes in the United States. Introduced in 1947, it serves as a core part of Chicago, Illinois. It covers the city’s downtown area and is synonymous with Chicago’s bustling energy and its historical significance as a financial and cultural hub.

If you’ve seen a 312 number, it’s highly likely from someone or some business within Chicago’s iconic downtown area.

A Brief History of the 312 Area Code

Before the days of smartphones and global telephony, the United States created area codes to handle increasing communication needs across the country. It was one of the original 86 area codes established in 1947 under the North American Numbering Plan (NANP).

Initially, it covered the entirety of the City of Chicago. However, as the population and demand for phone numbers grew, Chicago required additional area codes. Over time, portions of the city were split and assigned new codes like 773 (for non-downtown Chicago areas) and 872 (overlaying both 312 and 773). Today, 312 is primarily reserved for the downtown core, maintaining its exclusivity and prestige.
