800-978-8664 / 8009788664

This is indeed Chase's Fraud Department. I just got a call from them letting me know that there was suspicious activity on my debit card. I checked my account online and found that a purchase I made yesterday was charged 3 times in a row. Thank you Chase!

This is NOT A VALID NUMBER!!! I got a call from this number asking them for my credit card number. Of course I did not give it to them but called the real chase number on the back of my card and spoke with a real Chase Representative and it is a scammer who is trying to get your card information. DO NOT GIVE THEM YOUR CARD INFO!!!! CHASE WOULD NEVER ASK YOU FOR THAT - THEY ALREADY HAVE IT!!!

It's legit! I just called Chase directly and verified that the number is indeed their fraud dept. When I called 800-978-8664 they were able to pull up my account using my name, I did not have to give them my card number OR social security number.

I just received a voice mail from this same number. I didn't call it back -- I went directly to the chase number I have on file and they confirmed that this 800 number is indeed a correct Chase number. I explained the fact the voice mail was from a man with broken english and that he didn't appear to know my name. She said they do have a call center in India and that's where this call originated from. Okay, fair enough -- but for all the money they save sending this work to India, how much did it just cost Chase to make a call, take a call, and still use an American body to get the job done?

Based on my recent experience it isn't chase. When i called the "real" chase fraud department, they asked questions totally differently and did not confirm this number. who ever this is, calls you when your card won't work anymore because chase blocks the account. They want you to give up your info so the card can get put back on....DON'T give out your personal info. Call the number on the back of your card instead of calling these creeps back. Another thing that makes this number suspicious is the fact they immediately ask for your card number and PIN...Several Chase employees themselves said they don't do that...the people on here saying it is legit are not telling the truth. Also a police report has been filed....good luck to you all.

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 got a call from this number. They asked for my full credit card number, my pin, my zip code and the number on the back of the card. I didn't give them one minute to finish asking for more info before I hung up & called the Chase number I know. They transferred me to the Fraud Department and they said I didn't get a call from them. They looked into it and after 30 (or so) minutes, called me back and said nobody from Chase called me. Turns out it was a "spoof" call where they had the correct Chase number displayed but it wasn't from Chase. So if you ever get a call from this number, hang up and call number on the back of your credit/debit card and take it from there. You will be much better off in the long run.

12/14/09, 1927h: received msg on voice mail. called back n talked to a steve who proceeded to ask for all account info, since i was not the one concerned, i handed it over to my wife who proceeded to give all the information. i then called the fraud dept of chase at 1-800-935-9935 and they verified this number as chase fraud dept. my beef is that something has to be done for the account holder to indeed verify that the person they speak to is indeed from the institution involved. they verify us but CAN WE VERIFY THEM?

In case you are still unsure to call 1-800-978-8664, I just called Chase and they do have this number for their fraud dept. So this is a LEGITIMATE number and you'll be fine.

Just got off with Chase, calling the # on the back of my card: 888.646.2583. I asked to be transferred to the fraud department and they gave me the # 1-800-978-8664. I spoke someone there who was rude and short. She did ask me for my complete card number, as well as a lot of other personal information for security confirmation. She had knowledge of fraudulent charges on my account and told me the account would be shut down. Then she hung up on me. Overall, I have found Chase to provide terrible service, most of their phone bankers are rude and unknowledgeable. However, as suspicious as their service seems, unless some criminal has actually hacked into their system completely, and taken control of their phone lines, which I seriously doubt, then this number is the real Chase fraud department number.
