The 343 area code was created by the North American Numbering Plan Administration (NANPA) on October 24, 2021, to alleviate the demand for telephone numbers in the 312 and 773 area codes, which had reached exhaustion. It became the first new area code in the Chicago area since the creation of the 708 area code in 1984.
