When you get a call from an unknown number, let it go to voicemail first to see if they leave a message identifying themselves. You can also use a reverse phone lookup service to check if the number is linked to a legitimate business or has been reported as spam. Never share personal information like your full name or address until you're sure who you're talking to, and consider using a call-blocking app to automatically screen suspicious numbers.
