512 area code
Austin and surrounding parts of Central Texas.
512 is associated with Austin and surrounding Central Texas communities. The 737 overlay serves the same numbering region. An Austin-area business can encounter either prefix, so customer records should retain the full ten-digit number rather than assume every local contact starts with 512.

Questions about 512
Is 737 a different market from 512?
737 overlays the 512 region. Both can be local Austin-area numbers; the prefix alone does not identify a particular Austin neighborhood or confirm a caller's address.
Is a 512 call safe to answer?
The 512 prefix identifies a numbering region, not a caller's identity or trustworthiness. Verify an unexpected request by contacting the organization through a number you already know.
Can I get a 512 business number?
Search the available numbers in VeraDial. Inventory changes, so a 512 number is not guaranteed. You can also keep your current carrier number and forward voice calls to a VeraDial line; existing texts stay with your carrier.
