I received a text message first, telling me to call that number and that my debit card may have been comprimised. I ended up calling the number on the back of my debit card and they told me exactly what was in the text message and voicemail.

If you get this message, you are going to want to call the CHASE DEBIT card number on the BACK of your card. We called the number on the back of our card and they transferred us to the FREUD department for Chase. Our card HAD been compromised. So, if you get a call from this phone number don't answer the call, instead call Chase Debit card and they will help you.

I answered. Caller informed me that I have suspicious activity on my credit card and asked for my personal information. (I didn't give it to him.) Here's the kicker. I have never had a credit card in my life and do not plan on getting one any time soon.

Chase called me after they noticed there were several attempts on my card used at a gas station in a city I've never been too. Should not use debit cards anymore!

It is a legitimate number. I didn't call back because people were saying it was fraudulent, then went to buy something and had my card declined. If you don't trust them, call the number on the back of your debot card and they will transfer you, but will clarify it is the correct number. Save yourself the embarrassment of having your card declined in a long line of customers!

I too called the number on the back of my Chase card regarding the 800.978.8664 number. It is the Chase debit card fraud prevention department. I had made an expensive purchase that was unusual for me and they were callign to make it was me that made the purchase. And, they called within 20 of the purchase. I greatly appreciated it!

800.978.8664 is a legit number from Chase debit card fraud prevention department. They called me and left a message when they detected suspicious activity in my account. I called Chase at the main number printed on the back of my debit card and confirmed that 800.978.8664 is from their debit card fraud prevention department. They then transfered me to that department and there was a pending charge on my business account that I didn't make.

Called the number printed on the back of my card, and asked them for the "Debit Card Fraud Prevetion Dept". The number THEY gave ME matched: 800-978-8664
