Area Code Overlay Approved for the Indiana 812 Area Code
Attention: Telephone Directory Publishers & Payphone Providers
To ensure a continuing supply of telephone numbers, the new 930 area code will be added to the area served by 812. The new 930 area code will serve the same geographic area currently served by the existing 812 area code, which generally covers the southern third of the state of Indiana serving communities such as Bloomington, Columbus, Evansville, New Albany and Terre Haute. This is known as an area code overlay.
What is an area code overlay?
An overlay is the addition of another area code (930) to the same geographic region as an existing area code (812). An overlay does not require customers to change their existing area code.
How does this affect telephone directory publishers & Payphone Providers?
As a result of the overlay, a new local dialing procedure requires callers to dial area code + telephone number. This means that all local calls in the 812 area code that are currently dialed with seven digits will need to be dialed using area code + telephone number.
Telephone Directories covering the 812 area code region must add the new 930 area code information and alert customers in the 812 area code about the new 10 digit local dialing procedure
What will be the new dialing procedure?
To complete local calls, the new dialing procedure requires callers to dial area code + telephone number. This means that all calls in the 812 area code that are currently dialed with seven digits will need to be dialed using area code + telephone number. The same dialing procedure will apply to telephone numbers assigned to the new 930 area code.
When will the change begin?
Beginning September 6, 2014, you must use the new dialing procedures, as described above for all calls. After this date, if you do not use the new dialing procedures, your calls will not be completed and a recording will instruct you to hang up and dial again.
Beginning October 6, 2014, new telephone lines of services may be assigned numbers using the new 930 area code
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.
Who may you contact with questions?
Customers with questions about the dialing procedure change should be directed to their local service provider.
Sincerely,
IN 812/930 Overlay Industry Committee Chairs
