The Illinois Commerce Commission announced on Monday the addition of a 464 area code to south suburban counties presently served by the 708 area code, including Homewood and Flossmoor.
The 464 area code will “overlay” the existing territory in order to supplement the telephone number supply. The 464 area code will be available for assignment only when all assignable prefixes in the 708 have been exhausted, which is not expected to occur until January of 2022.
The 708 area code serves most of western and southern Cook County and eastern and southern Will County . . .
