About the 737 region
737 covers Austin in Texas, including Bastrop, Bee Cave, Bertram, Briggs and Buchanan Dam. The code has been in service since 2013.

- Never share verification codes, payment details, or remote access during an unsolicited call, even if the caller claims to be your bank or a government agency.
- When a 737 call pressures you to act immediately, hang up and contact the organization directly through its official number.
