Is 830 a scam or spam risk?
830 is a legitimate geographic area code, not a premium or toll line, so a call from it costs you nothing extra. That said, scammers frequently spoof real local area codes to look familiar on caller ID. A genuine 830 number on your screen is no guarantee the caller is in New Braunfels, TX or trustworthy. See spam & scam-risk area codes for how spoofing works and how to respond.
