All consumers in Indiana’s 812 telephone area code should start using 10 digits, rather than seven, to make local phone calls starting this weekend, according to a news release issued by the Indiana Utility Regulatory Commission.
Local calls made with seven digits will still work until early September to give consumers in the 812 area code ample time to adjust to the changes.
The change in dialing patterns is necessary for the introduction of the new 930 area code, which will be implemented in the fall, according to the release. 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 as an existing area code. An overlay does not require customers to change their existing phone numbers, according to the release.
The new area code is being implemented due to projections that all numbering supplies for the 812 code will be exhausted in 2015. To ensure a continuing supply of telephone numbers, the new 930 area code will be added to the region.
The IURC ordered the overlay in July 2013.
Effective March 1, you should start using 10 digits when dialing a number in the 812 area code. However, if you forget, your call will still be completed.
Beginning Sept. 6, you must use 10 digits when dialing for all local phone calls. After this date, if you do not use the new dialing procedures, your call will not be completed and a recording will instruct you to hang up and dial again.
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.
