Central Texas about to get second area code: 737
Callers in the Austin area code may soon be required to begin dialing the area code in order to complete the calls. Austin continues to grow and in order to provide a continuous supply of phone number a new area code (737) has been implemented.
Since two area codes will not be servicing the same geographic area, local callers may be required to include the area code when dialing, including calls within the same area code. Check with your landline or cellphone providers for more details and the exact implementation dates.
In addition to the long standing 512 area code, the new area code of 737 has been implemented as an available area code for the Austin area. See the blue area in the image.
If you have any questions regarding this information, please call your phone provider or visit the Texas Public Utility Commission's website.
