Residents in portions of Cook and Will counties who obtain a new phone number may get a new area code as well.
As of Friday, customers in the current 708 area code region, which includes Chicago's south suburbs, "may be assigned a number in the new 464 area code when they request new service or an additional line," according to the Illinois Commerce Commission.
The ICC previously approved "the implementation of the new 464 area code" as telephone numbers in the south suburban region continue to be in high demand.
The 464 area code will co-exist everywhere in the region with the 708 area code, according to the ICC. Also, it's important to note your current area code won't change.
The ICC shared the following notes for telephone customers to know about the 464 area code overlay:
- Telephone numbers, including current area code, will not change.
- The price of a call, coverage area, or other rates and services will not change due to the overlay.
- What is a local call now will remain a local call.
- Customers in the overlay region will continue to dial 1+10 digits for local calls within and between the overlay area codes, and 1+10 digits for long distance calls.
- Customers can still dial just three digits to reach 911, as well as 211, 311, 411, 511, 611, 711 or 811 if those are currently available in their community.
To get a sense of who this affects, the 708 area code covers most of western and southern Cook County and eastern and southern Will County, including: Alsip, Beecher, Bellwood, Berwyn, Blue Island, Bridgeview, Broadview, Burbank, Calumet City, Chicago Heights, Chicago Ridge, Country Club Hills, Crest Hill, Crete, Dolton, Elmwood Park, Evergreen Park, Flossmoor, Forest Park, Glenwood, Harvey, Harwood Heights, Hazel Crest, Hickory Hills, Homewood, Justice, La Grange, Lansing, Lyons, Markham, Matteson, Maywood, Melrose Park, Midlothian, Mokena, Norridge, Northlake, Oak Forest, Oak Lawn, Oak Park, Orland Park, Palos Hills, Palos Park, Park Forest, Richton Park, River Forest, River Grove, Riverdale, South Holland, Steger, Tinley Park, Westchester, Western Springs and Worth.
