To ensure a continuing supply of telephone numbers, the new 930 area code will be added to the area served by 812. This is known as an area code overlay. Get ready to change the way you dial your local calls!

What is the new local 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.

When will the change be mandatory?

Beginning February 7, 2015, you must use the new dialing procedures, as described above for all local calls. After that date, if you do not use the new dialing procedures, local calls will not be completed and a recording will instruct you to hang up and dial again

Telephone network changes have already been made, so there is no reason to wait. All customers can and should begin using the new ten-digit dialing procedure for local calls before February 7, 2015.

Who will be affected?

The 812 area code generally covers the southern third of the state of Indiana serving communities such as Bloomington, Columbus, Evansville, New Albany and Terre Haute. The new 930 area code will be added to serve the same geographic area currently served by the existing 812 area code.

Why is the change necessary?

To ensure a continuing supply of telephone numbers, the new 930 area code will be added to the area served by 812. Since the two area codes will now serve the same geographic region, the area code must be used when dialing any local telephone number, including calls within the same area code.

Beginning March 7, 2015, new telephone lines or services may be assigned numbers using the new 930 area code. Callers must use the new dialing procedures for local calls in the new 812/930 area code.

What will you need to do before February 7, 2015 to implement the 812/930 overlay?

In addition to changing your local dialing procedures, all services, automatic dialing equipment, or other types of equipment that are programmed with a 7-digit number will need to be reprogrammed to use the new dialing procedures (10-digit dialing). Some examples are life safety systems, PBXs, fax machines, Internet dial-up numbers, medical, alarm and security systems, gates, speed (memory) dialers, call forwarding settings, voicemail services, etc. You may also want to check your website, business stationery, printed checks, contact information, pet ID tags, advertising materials and signage to ensure your area code is included. Important safety and security equipment, such as medical alert devices, and alarm and security systems must be programmed to use 10-digit dialing. Many systems operate on 10-digit dialing by default but some older equipment may still use 7-digits. Please contact your medical alert or security provider if this change hasn't been confirmed to have been reprogrammed to the 10 digit dialing.

What will remain the same?
  • Your telephone number, including the current 812 area code, will not change.
  • The price of a call, coverage area, and 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 will still have to dial 1+area code + telephone number (11-digit dialing) to place long-distance calls within the 812/930 Area Code.
  • You can still dial just three digits to reach 911.
  • 211, 311, 411, 511, 611, 711 or 811 if available, will only require three digits.
