Starting June 1, dialing the phone in and around Austin is going to get a little more complicated. That’s when Central Texans will be required to dial the area code plus the phone number for local calls.
Few telephone numbers are still available in the 512 area code, and new phone lines might be assigned to a second area code, 737, as early as July 1, according to the state’s Public Utility Commission.
Calling 311 for city information or 911 for emergencies will not be affected.
Those who get to keep the 512 area code are holding on to a little piece of history. It was among the country’s first when the area code system was created in 1947, and once served all of Central and South Texas. The Austin area got 512 all to itself in 1999, after San Antonio, the Hill Country and South Texas received their own area codes.
With the change to 10-digit dialing, the PUC recommends updating pet ID tags, stationery, websites and other contact information to include the area code, as well as reprogramming alarm systems, mobile phone contact lists and autodial systems.
