Verify any unknown number before engaging. With no reports on this caller, treat it as potentially suspicious—spam often flies under the radar initially. Block the number if calls persist without leaving a voicemail, and report to your carrier or FTC to build awareness. Enable call screening on your phone to filter unknowns automatically. Stay cautious: legitimate callers identify themselves promptly. If it's a one-off, it might be a wrong dial, but err on the side of caution to protect personal info.
