With new telephone numbers in Chicago’s southern suburbs in high demand, the state approved the implementation of the new 464 area code to overlay the existing 708 area code region.
Starting on Jan. 21, customers in the 708 area code overlay region may be assigned a number in the new 464 area code when they request new service or an additional line.
The 464 area code will co-exist everywhere in this region with the 708 area code. Customers receiving a 464 area code will be required to dial 1+ the area code and phone number for all local . . .
