Several public hearings are set to take feedback on an additional area code proposed for much of central Indiana. The “317” area code is projected to run out of numbers in 2017 and the telecommunications industry is requesting to “overlay” a new number. September 24, 2014

News Release

INDIANAPOLIS, Ind. – The Indiana Office of Utility Consumer Counselor (OUCC) is encouraging consumers to comment on proposed changes to central Indiana's 317 telephone area code. Consumers may comment by:

1. Speaking at any of the Indiana Utility Regulatory Commission's (IURC’s) upcoming public field hearings, or

2. Sending written comments to the OUCC by the close of business on December 29, 2014.

IURC public field hearings are scheduled for:

-Indianapolis: Friday, September 26, 2014, 10:00 a.m.: PNC Center, 101 W. Washington St., Room 222.

-Carmel: Wednesday, October 1, 2014, 6:00 p.m.: Carmel Clay School District Office Boardroom, 5201 E. Main St.

An OUCC informational session will start 30 minutes before each field hearing. During the IURC hearings:

-Oral and written consumer comments will be accepted.

-Comments carry equal weight whether they are oral or written, and will become part of the case's evidentiary record.

-Commissioners are not allowed to answer questions. However, OUCC and IURC staff will be available before, during and after each hearing.

The 317 area code, covering Indianapolis and most of its suburbs, is projected to run out of numbers in 2017. As a result, the telecommunications industry has filed a formal request with the IURC to add a new area code using the “all services overlay” method. This is the same approach currently being implemented in Indiana’s 812 area code, where the new 930 area code will debut in the coming months.

Under an all services overlay:

-All consumers in the 317 area would keep their current 317 numbers.

-The new area code, when added, would be superimposed over the entire 317 area. It would be assigned only to new customers/phones/devices throughout the region.

-Ten-digit dialing (area code + number) for local calls would eventually become mandatory throughout the 317 area.

-Toll calls would still use 11 digits (1 + area code + number).

-Consumers would not need to reprogram existing cell phones, fax machines, etc. with new numbers if the pre-programmed numbers already include the area code.

Indiana is one of 39 states, along with most Canadian provinces and the Caribbean, that have been required to add new area codes over the last two decades due to the proliferation of wireless phones and other communications devices.

All new area codes that have been introduced in the United States since 2008 have been implemented through the overlay method. Before 2008, most new area codes were implemented using a geographic split. Under geographic splits, consumers were able to continue using seven-digit dialing for local calls. However, large numbers of consumers were required to change their numbers. As a result, businesses, not-for-profit organizations, government agencies, and other entities were required to change signage, advertising, business cards, and stationery to reflect new numbers, and were required to incur the costs of doing so.

With an overlay, only documents and signage showing seven-digit telephone numbers would have to be changed. For existing numbers, the only update required under the proposed overlay would be the addition of “317.” The gradual transition to ten-digit dialing would allow businesses and other entities to update materials in the normal course of reprinting or reordering, making it less costly and less time-consuming for many consumers to adjust to the changes.

The OUCC, the state agency representing consumer interests in cases before the IURC, is scheduled to file testimony in this case on January 6, 2015.
