Austin-area mandatory 10-digit dialing starts June 1; 9-1-1 not affected

Wednesday, May 15, 2013

Remember to reprogram those phones! With the introductory six-month grace period ending, mandatory 10-digit dialing in Central Texas starts June 1, 2013.

The change, needed to accommodate an expanding population and demand for more phone numbers, also includes a new, additional area code coming this summer. 

First announced last year, the move echoes other communities across the country whose days of seven-digit dialing are a thing of the past. It affects Bastrop, Burnet, Caldwell, Hays, Lampasas, Milam, Travis and Williamson counties.

Key components of the change, also called an "overlay":

  • Optional 10-digit dialing, or dialing the applicable area code and seven-digit phone number, ends its six-month introductory period on May 31, 2013.
  • Mandatory 10-digit dialing starts June 1, 2013; calls will not be completed without it.
  • Starting July 1, 2013, new phone lines may receive the new "737" area code, an addition to the area already served by "512."
  • Eventually all new telephone numbers within the 512 area will be assigned the 737 area code.
  • Customers can keep the 512 phone numbers they already have.
  • The three-digit 9-1-1 local emergency number will remain the same.

Customers can contact their local phone-service provider for more information, or visit the "Texas Area Codes" section of the state Public Utility Commission website. > Go
