Part of our guide: What to do if you got scammed →
Your card can be stopped faster than a scammer can drain it, so act now and you're in a strong position. The single most effective step is to call your bank and freeze the card before any charge clears. Everything else follows from that one call.

Card-detail scams target people who fear losing access to their money, using a fake 'your card is blocked' alert to trigger a panicked reply. The look-alike link and 24-hour deadline push you to confirm details before you verify the sender. It works best on anyone who banks by phone and is used to entering card numbers, making one more prompt feel routine.
Illustrative example of the pattern, not a real message someone received.
How to verify it yourself
- Find your bank's real phone number on the back of your card or in its official app, not any number from the message that tricked you.
- Tell them exactly what was shared: card number, expiry, security code, and PIN if you entered one. They will freeze or reissue based on that.
- Watch your transactions closely for small 'test' charges, which scammers use to check a card before a larger one.
- If you typed the card details into a website, treat any password you use there as exposed too and change it.
Common questions
I gave my card number to a scammer can they use it
They can attempt online purchases, but you can shut that down by freezing the card now. The sooner you call your bank, the smaller the window they have.
how do I stop a scammer who has my card details
Call your bank's official number and ask them to freeze or cancel the card and issue a new one. This is the fastest way to make the stolen details worthless.
will the bank refund fraudulent charges
In most cases you are protected against unauthorized charges when you report them promptly, so contact the bank right away and dispute anything you didn't make. Keep a record of the date and time you reported it.
do I need to worry if I only gave the card number not the PIN
Yes, a card number, expiry, and security code are enough for many online purchases, even without the PIN. Freeze the card regardless of how much you shared.
If you already responded
- Call your bank's real number, printed on the back of your card or in the official app, and ask them to freeze or cancel the card immediately and reissue a new one.
- Tell them precisely what was exposed, the full card number, expiry date, security code, and PIN if you entered one, so they can flag the account correctly.
- Review recent transactions and dispute any charge you didn't make; report each one promptly so you keep your fraud protection.
- If you entered the card on a website, change the password for any account tied to it and turn on two-factor authentication.
- Report the fraud at reportfraud.ftc.gov, and watch for a follow-up 'refund' or 'fraud department' call that asks for more details. That is a common second wave. Never give card or code information to an incoming caller; hang up and dial the bank yourself.
If you were already hit, expect a follow-up
One more thing to expect: after a scam, your details often land on lists that get reused, so you may be contacted again, sometimes by people posing as investigators, your bank's "fraud team," or "recovery agents" who promise to get your money back for an upfront fee. That follow-up is a second scam. No legitimate service charges a fee to recover funds.
