737 Area Code

The 737 area code is a telephone area code in the state of Texas, USA. It was introduced in 2013 as an overlay to the 512 area code, which had served the Austin metropolitan region since the early years of the North American Numbering Plan. The addition of 737 was necessary due to the rapid growth of Austin and surrounding communities, fueled by technology companies, universities, and a booming population.

Understanding the 737 Area Code

The 737 area code is unique because it does not represent a separate geographic split but instead overlays the existing 512 service area. This means both 512 and 737 numbers serve the same region. The overlay system ensures that new phone numbers can still be issued without changing existing numbers. Austin, the capital of Texas and a major tech hub often called �Silicon Hills,� is the core of this region.
