SPRINGFIELD, Ill. — A new area code is set to begin operating in the south suburbs on Friday.

Customers currently in the 708 area code may be assigned a phone 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.

State officials want to relay the following.

  • 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.
