Ten-digit dialing to Indiana's 812 area code starts Saturday

Posted: Updated:
Indiana (FOX19) -

On Saturday, consumers in Indiana's 812 telephone area code will start using ten digits, rather than seven, to make local phone calls.

For example, individuals will call 812-555-5555 rather than simply 555-5555.

Local calls made with seven digits will still work until early September, to give consumers in the 812 area 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 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 (930) to the same geographic region as an existing area code (812). An overlay 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. To ensure a continuing supply of telephone numbers, the new 930 area code will be added to the entire 812 region which has covered southern, south-central, and parts of west-central Indiana since 1947, including Bloomington, Columbus, Evansville, New Albany, Terre Haute, and other cities.
