You’re standing at the grocery store. The line is long. People are staring. You swipe your card, and it’s declined. Then your phone buzzez with a text asking if you just spent $2,400 at a luxury watch shop in Dubai. Your heart drops. You need the Chase bank fraud protection number right now, but searching for it while you're stressed is a recipe for getting scammed by a fake "customer support" ad on Google.
Let’s get the big one out of the way immediately. If you think someone is using your account right this second, flip your card over. The most reliable Chase bank fraud protection number is literally printed on the back of your debit or credit card. It’s usually 1-800-935-9935 for personal banking, but if you've lost the card or it’s been stolen, you can hit them up at 1-800-432-3117 for credit cards or 1-800-935-9935 for debit issues.
Don't wait.
Why Finding the Real Chase Bank Fraud Protection Number Matters
Scammers are getting incredibly good at "Search Engine Optimization" for bad reasons. They buy ads that look exactly like Chase support. You click, call a number, and a very professional-sounding person asks for your PIN to "verify" your identity. Chase will never do that. Not ever.
The official numbers are your lifeline.
Banking fraud isn't just about someone buying a Rolex on your dime. It's about identity takeover. According to the Federal Trade Commission (FTC), Americans lost over $10 billion to fraud in 2023, and a huge chunk of that was through imposter scams where people thought they were talking to their bank. If you aren't 100% sure about the voice on the other end, hang up. Dial the number you found on your actual bank statement or the official Chase mobile app.
The Nuance of the "Fraud Alert" Text
Most of the time, the Chase bank fraud protection number comes to you.

Chase sends those automated texts from a "short code"—usually 28107. They'll ask if you authorized a charge. You reply YES or NO. If you reply NO, your card is instantly frozen. This is great, but here is where people get tripped up: the follow-up. A scammer might call you five minutes after that text, spoofing the Chase caller ID, claiming they are from the fraud department.
They might even know your last four digits.
Honestly, the safest move is to tell them you’ll call them back. Then, manually dial the Chase bank fraud protection number yourself. If the person on the phone gets pushy or tells you that you "must act now or lose everything," that is a massive red flag. Real bank employees are generally patient and won't pressure you into moving money to a "safe account" via Zelle or wire transfer.
Dealing with Credit vs. Debit Fraud
There is a huge legal difference between fraud on your Sapphire Preferred and fraud on your Total Checking account.
With credit cards, you’re protected by the Fair Credit Billing Act. Your liability for unauthorized charges is capped at $50, and honestly, Chase almost always waives that. It’s their money on the line, not yours. You report it, they strike the charge, and you get a new card in the mail. Easy.
Debit is a different beast. That’s your rent money. Your grocery money.

Under the Electronic Fund Transfer Act, your protection depends on how fast you call the Chase bank fraud protection number. If you report it within two business days, your liability is limited to $50. Wait longer than that, but less than 60 days, and you could be out $500. After 60 days? You might be on the hook for the whole thing. This is why checking your app daily isn't just paranoia—it's financial self-defense.
International Travelers and the Fraud Trap
If you're in Paris and your card stops working, calling an 800 number isn't always easy or free. For international fraud issues, Chase has a specific collect-call line: 1-302-594-8200.
You have to use a landline or a service that allows collect calls, but it's the fastest way to get a human who can unblock your account while you're abroad. Pro tip: before you leave the country, set a travel notice in the Chase app. It takes ten seconds and prevents that awkward moment where your card is declined at a bistro because Chase thinks your account was hacked by a croissant enthusiast.
How to Spot a Fake Representative
We’ve all seen the news stories. Someone loses their life savings because they thought they were talking to "Michael from Chase Fraud Prevention."
Here is the reality: Chase will never ask you for your full Social Security number over the phone if they called you. They won't ask for your password. They definitely won't ask for a one-time passcode that was just sent to your phone. Those passcodes are for you to enter into a secure site, not to read aloud to a stranger. If "Michael" asks for that code, Michael is currently trying to log into your account from a laptop in another state.
- Check the Tone: Is the caller frantic? Scammers use "urgency" to bypass your logic.
- Verify the Request: Do they want you to move money? Chase will never ask you to transfer money to "yourself" at another bank to "protect" it.
- Ghost the Call: If it feels weird, hang up. Call the number on your statement. If there’s a real problem, the legitimate agent will see the notes on your account.
What Happens After You Call?
Once you've dialed the Chase bank fraud protection number and confirmed the unauthorized activity, things move fast.

The bank will kill your current card immediately. If you have "Digital Wallet" set up on your iPhone or Android, Chase can often push a new, virtual card to your phone within an hour. This is a lifesaver. It means you can still buy gas or food while you wait 3-5 business days for the physical plastic to arrive in your mailbox.
They will also start an internal investigation. This usually takes about 10 business days for debit cards, though they often provide a "provisional credit" so you aren't broke while they work. For credit cards, the charge just sits in a "disputed" status and doesn't count toward your minimum payment.
Steps to Take Immediately
If you're reading this because you're worried about a specific transaction, don't finish this article. Do this instead:
- Lock your card in the app: Go to the Chase Mobile app, tap your account, and look for "Lock/Unlock card." This stops all new purchases but allows recurring bills like Netflix to potentially go through.
- Call 1-800-935-9935: This is the primary Chase bank fraud protection number for most users.
- Change your password: If you think your online banking was compromised, update your password and enable Two-Factor Authentication (2FA) immediately.
- Review your statements: Look back at the last 30 days. Scammers often do "micro-transactions" of $1 or $2 to see if you're paying attention before they go for the big hit.
The most important thing to remember is that you are your own best advocate. Chase has massive systems—AI, machine learning, 24/7 monitoring—to catch fraud, but they aren't perfect. Sometimes a legitimate $500 purchase at Home Depot gets flagged, and a $500 scam at a gas station doesn't.
Stay vigilant, keep the Chase bank fraud protection number saved in your contacts (the real one!), and never, ever give out a one-time passcode over the phone. You've worked hard for your money; don't let a "spoofed" phone call take it away from you in sixty seconds.
