512 Area Code

Port Your Number or Get an Austin Overlay Code with DialLink

Establish a Local Presence in Central Texas

No Office Needed

Want to connect with customers in Austin, Round Rock, or San Marcos? A 512 area code helps you stand out in the capital of Texas — a city known for innovation, government, and rapid growth. But due to limited availability, new 512 numbers are no longer being assigned. If you already have a 512 number, you can easily port it to DialLink. If not, overlay code 737 is available and covers the exact same region.
With DialLink, SMBs and startups can secure a local Austin number and manage their calls and messaging through an intuitive, AI-powered cloud phone system — no hardware, no hassle, just smart business communications.

Why Choose a 512 Area Code?

The 512 area code is one of the original area codes in Texas, covering Austin, the state capital, and nearby cities like Round Rock, Georgetown, and San Marcos. It's widely recognized throughout Texas and has become closely associated with Austin's booming tech, real estate, and cultural scenes.
Due to high demand, the 737 area code was added as an overlay to expand the number pool in this fast-growing region. Both codes now serve the same area, giving you the same local credibility with modern availability.
