312 Area Code Facts

The 312 area code is often associated with the vibrant culture, diverse communities, iconic skyline, and rich history of Chicago.
In 1989, it was split, and a new 773 area code was introduced, to accommodate the growing population and increased demand for phone numbers.
Many famous landmarks and attractions, such as Millennium Park, Navy Pier, and the Art Institute of Chicago, are located within 312.
This area code is part of the North American Numbering Plan (NANP), which includes the U.S., Canada, and various Caribbean countries.
