The phone rings. The screen says "Chase Bank", or "IRS", or even your own bank's real customer service number. A calm professional explains there's been suspicious activity on your account, and they need to verify a few things to protect you.
It feels real because the number is real — or at least, it looks that way on your screen. Here's why, and what to do about it.
How scammers fake the number on your screen
"Caller ID spoofing" is shockingly easy. There are commercial services — many of them used legitimately by businesses — that let a caller display any number they choose. Scam operators use these to display the actual phone number of your bank, the Social Security Administration, a hospital, even a relative.
Important truth
The number on your screen is never proof of who is calling.
The one rule that ends imposter calls
If you remember nothing else from this article, remember this:
If a caller claims to be from a company you do business with, hang up and call them back using a number you already trust — printed on your card, on a recent statement, or on their official website you typed in yourself.
A real bank, real police officer, or real government agent will never object to you calling them back. A scammer always will, because the call-back route bypasses their script.
The most common imposter scripts in 2025
The "fraud department" call
"We've detected a $749 purchase from your card in another state. Was this you?" When you say no, they offer to "secure your account" by moving your money to a "safe account" or by reading them a code they just sent. Both are the actual theft.
The "tech support" call
"We detected viruses on your computer." They ask you to install a remote-access tool (AnyDesk, TeamViewer, UltraViewer). Once installed, they own your screen, your files, and your banking sessions.
The "grandchild in trouble" call
A young voice — sometimes a cloned voice from social media — says "Grandma, it's me, I'm in jail, please don't tell mom and dad." A second adult takes over and demands bail money in gift cards or cash. The emotional shock is the weapon.
The "government agency" call
IRS, Social Security, immigration, local police. They threaten arrest, deportation, or seizure of assets. Real US agencies do not call to demand immediate payment, and they never accept gift cards.
Phrases that should end any call instantly
- "Stay on the line, don't hang up."
- "Don't tell anyone — this is confidential."
- "Buy gift cards and read me the numbers."
- "Withdraw cash and meet a courier."
- "Install this app so I can help you."
- "What's the code we just texted you?"
A safe-script for hanging up
Some people find it hard to be rude, even to scammers. A polite, firm exit line:
"Thank you. I'm going to hang up and call back on the number on my card. If this is legitimate, we'll continue then." Then hang up. You don't owe them an argument.
Set up your circle of trust
Decide today on one person — a child, sibling, neighbor — that you will always call before sending money in any unusual situation. Tell them you've chosen them. That single agreement defuses 80% of phone scams.
If you've already been hit
- Call your bank's fraud line (number on your card) immediately. Speed of reporting often determines whether the money can be recovered.
- Change your online banking password and enable two-factor authentication.
- If you installed remote-access software, uninstall it and reboot. Have your device checked by someone you trust.
- File a report — in the US: reportfraud.ftc.gov.
- Tell your circle. Scammers often come back for the same person.
