Mandatory 10-Digit Dialing is Here For Callers in the Indiana 812 Area Code

Beginning Feb. 7, 2015, all local calls made within the Indiana 812 area code must be placed using 10-digit dialing (area code + the 7-digit telephone number).

To ensure a continuing supply of telephone numbers, a new area code, 930, will be added to the 812 area code region which serves southern Indiana, including communities such as Bloomington, Columbus, Evansville, New Albany, and Terre Haute. The Indiana Utility Regulatory Commission (IURC) ordered an area code overlay for the area served by 812 in July, 2013. The new 930 area code will be added to the current 812 area code geographic region through an overlay. Customers in the current 812 region may be assigned 812 or 930 phone numbers.

Residential and business customers within the existing 812 area code should be prepared for the introduction of the new 930 area code. Customers should update their contact information to include the area code with their phone number on all documentation, including medical records, emergency contacts, and employment paperwork.

What is an area code overlay?
An overlay is the addition of another area code to the same geographic region as an existing area code. In Indiana, the 930 area code is being added to the region currently served by 812. An overlay does not require customers to change their existing area code.

Beginning March 7, 2015, new telephone lines or services may be assigned numbers using the new 930 area code.

The most important facts that consumers and businesses need to know about the upcoming 930 area code overlay are:

• Your telephone number, including current area code, will not change.
• You will need to dial area code + telephone number for all local calls.
• You will continue to dial 1+ area code + telephone number for all long distance calls.
• What is a local call now will remain a local call.
• The price of a call, coverage area, or other rates and services will not change due to the overlay.
• 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.

Customers should identify their telephone number as a ten digit number (Area Code + 7 digit telephone number), and include the area code when giving the number to their friends, family, business associates, and customers, etc.
Customers should ensure that all services, automatic dialing equipment, applications, software, or other types of equipment recognize the new 930 area code as a valid area code. Some examples are life safety systems, fax machines, Internet dial-up numbers, alarm and security systems, gates, speed dialers, mobile phone contact lists, call forwarding settings, voicemail services, and similar functions. Be sure to check your business stationery, advertising materials, personal checks, and your personal or pet ID tags to ensure the area code is included in your telephone number.

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 you are not sure whether your equipment needs to be reprogrammed to accommodate the upcoming change to 10-digit local dialing.

Remember that all local calls must be programmed using 10-digits and you need to add “1” for all long distance calls.
