Mandatory 10-Digit Dialing Less Than A Month Away For 812 Area

Staff Report

Indiana utility officials say 10-digit dialing in southern Indiana’s 812 area code will become mandatory in less than a month, February 7.

According to the Indiana Utility Regulatory Commission (IURC), the mandatory dialing period has been established to help customers prepare for the addition of the 930 area code to southern Indiana, which begins March 7. Once mandatory dialing begins, customers will be required to dial the area code, along with the seven-digit phone number, when making calls within the 812 area code, including local calls.

Previously, the IURC delayed the start date for mandatory 10-digit dialing after it became aware of concerns regarding the ability of critical segments of the business community and telecommunications providers to prepare for the switch to mandatory dialing, specifically those serving the medical and law enforcement industry.

In anticipation of the mandatory dialing period, customers are encouraged to begin practicing 10-digit dialing, check with any alarm service providers or providers of other services that use the telephone network to ensure the customer’s equipment is capable of using 10-digits, and to update pertinent medical records, business materials, personal contacts, and pet I.D. tags with all 10 digits of their phone numbers.

It should be noted that this transition will in no way affect calls to emergency lines such as 9-1-1 and 2-1-1.

The 930 area code is being added through the “overlay” method, which has been used for all new area code additions in the United States since 2008. That means people with 812 numbers won’t be affected, but any new phone numbers will get a 930 area code.

The 930 area code will be added to or superimposed over the entire 812 region which has covered the lower third of Indiana since 1947 and includes the cities of Bloomington, Columbus, Evansville, New Albany, and Terre Haute.
