Welcome to Austin Area Code 737!

TX-512Starting in July all new cell phone and landlines in the Austin area will be assigned the 737 area code and we will all be required to dial 10 digits on all phone calls. The continued population increase in the capital has made it necessary to add the new area code.

The main area code, 512, was one of the original area codes established in October 1947. At the time, it covered most of the south-central portion of Texas, from the Gulf of Mexico to the Mexican border. Besides Austin, it included San Antonio, Corpus Christi, Brownsville, Harlingen and McAllen.

Despite the presence of both San Antonio and Austin, 512 remained unchanged for 45 years. Finally, in 1992, the western part of its territory, including San Antonio, was split off as area code 210, making 512 the last of Texas' original four area codes to be split. On February 13, 1999, it was reduced to its current size when the southern portion (including Corpus Christi) was split off into 361.
