Area Code Overlay
Area Code Overlay Approved for the Illinois 217 Area Code
What is an area code overlay?
Who will be affected?
What will be the new dialing procedure?
Effective August 29, 2020, you should begin using the new dialing procedures whenever you place a call from the 217 area code. If you forget and dial just seven digits, your call will still be completed.
Beginning February 27, 2021, you must use the new dialing procedures, as described above. On and after this date, if you do not use the new dialing procedures, your calls will not complete and a recording will instruct you to hang up and dial again including the area code.
Beginning March 27, 2021, new telephone lines or services may be assigned numbers using the new 447 area code.
Start using 10-Digit dialing now to get ready for the change!
What will you need to do?
What will remain the same?
- Your telephone number, 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 regardless of the number of digits dialed.
- You can still dial just three digits to reach 911.
- If 211, 311, 411, 511, 611, 711 or 811 are currently available in your community, you will still dial these codes with just three digits.
