930 Area Code Implementation


Although the Federal Communications Commission (FCC) has broad jurisdiction over telephone number issues, it delegates authority to the states on how to introduce new area codes. Therefore, when a petition is filed with the IURC, the agency does not determine whether to implement area code relief; rather, it decides how it should be done based on the evidence presented.

On August 3, 2012, the North American Numbering Plan Administration (NANPA) filed a petition for relief in the 812 area code. According to the most recent projections by the NANPA, the 812 area code serving southern Indiana is scheduled to run out of assignable telephone numbers in the second quarter of 2015. Although steps have been taken to delay the area code's exhaust date, there comes a point in time when relief is necessary. After conducting public hearings throughout the affected region and weighing evidence submitted in the case, the IURC decided to overlay a new area code to provide more numbers for the growing region. Read below for more information about implementing the new 930 area code and how it can affect you.


The most recent area code to exhaust in Indiana was 812. In this case, an area code overlay was found to be the best solution based on the testimony given by industry representatives and the public. Ultimately,  the IURC determined to overlay the new 930 area code to serve the same geographic area as the existing 812 area code. Prior to this, other areas in the state had been split to accommodate the growing need for numbers. The evolution of area code relief is represented below:

930 Area Code Implementation Schedule

On September 13, 2013, the Indiana telecommunications industry met to discuss implementation of the new 930 area code, which will serve the same geographic area as the existing 812 area code. As a result of this collaborative effort, the following timeline was developed for the implementation of the new area code.

February 1, 2014 – Customer Notification No. 1

  • Industry websites will be updated and customers will be notified of the new area code plan, including information about 10-digit dialing and which areas will be affected.

March 1, 2014 – Permissive 10-Digit Dialing Begins

  • Permissive dialing allows callers to connect with the telephone number they are trying to reach using the old method. During this transitional period, customers should make an effort to begin using the new method.  

April 7, 2014 – 930 Central Office Codes Available Through NANPA

  • Telecommunications Carriers will be able to order central office codes with the new 930 area code from NANPA.

Frequently Asked Questions

How quickly will the new 930 area code be implemented?

The implementation planning started in September 2013. The overlay of the new 930 area code is introduced in two steps to familiarize consumers with the changes and allow time for adjustments. These steps are detailed below:

  • Permissive Dialing - Permissive dialing allows callers to connect with the telephone number they are trying to reach using the old method. From March 1 to September 6, 2014, customers should make an effort to begin using the new method.
  • Mandatory Dialing - When the transitional period ends on September 6, 2014, callers are notified if they are still using the old method. Incorrectly dialed calls receive a recorded announcement informing them of the new procedure. In order to proceed with the call, they must use the appropriate area code. After the recording period ends, callers who do not use the correct area code may reach a wrong number.
