10-digit dialing hits 812 area code

All consumers in Indiana’s 812 telephone area code should start using 10 digits, rather than seven, to make local phone calls. (For example, 555-5555 will need to be dialed 812-555-5555.) Local calls made with seven digits will work until early September to give consumers in the 812 area time to adjust.
The change in dialing patterns is necessary for the introduction of the new 930 area code, which will be implemented this fall. The new code is being added through the ‘overlay’ method, which has been used for all new area code additions in the United States since 2008. (An overlay is the addition of another area code to the same geographic region and does not require customers to change their existing phone numbers.)
The new area code is being implemented due to projections that all numbering supplies for 812 will be exhausted in 2015. The Indiana Utility Regulatory Commission ordered the overlay in July 2013, following a year-long case.
Beginning Sept. 6, callers must use 10-digit dialing for all local phone calls. After this date, calls will not be completed and a recording will instruct the caller to hang up and dial again. The price of a call, coverage area or other rates and services will not change due to the overlay.
Beginning Oct. 6, new telephone lines or services may be assigned numbers using the new 930 area code. In some cases, a customer with an 812 landline number who moves to a new location may be assigned a 930 number.
All long-distance calls still require callers to use 1 plus the area code plus the phone number.
You can still dial just three digits to reach 211, 411, 811 or 911. The same applies to 311 service where applicable.
Consumers should also 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. They should also make sure that all pre-programmed numbers for local calls are set to include the 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. Business stationery, advertising materials, personal checks and personal or pet ID tags and microchips should also be checked to ensure that the phone number includes the 812 area code.
