TL;DR: Caller ID spoofing is when a scammer fakes the phone number that appears on your caller ID, making a call look like it's coming from a trusted source such as your bank or a local number. Never trust caller ID alone to verify who's calling. Hang up and call the organization back using a number from their official website.

How Caller ID Spoofing Works
Using widely available spoofing software, a scammer can display any number they choose — often your bank's real customer service line, a government agency, or even a number similar to your own. This makes vishing (voice phishing) calls far more convincing.
Warning Signs to Watch For
A call from a number that matches a real organization but with an unusual tone, urgency, or request that the real organization wouldn't make, or a call from what looks like your own number.
How to Protect Yourself
Never trust caller ID alone to verify who's calling. Hang up and call the organization back using a number from their official website.
