It is very reasonable that there is some confusion about this number. It certainly seems like a legitimate Chase number, but it is not. I received four calls - three while I was writing this message - from this number. The first call I answered, but immediately muted myself. The female on the other end said hello a number of times, but then stated she could not hear me. Identified herself as Chase Bank and was calling regarding a card number that I have, but haven't used in years. She said there was fraudulent activity and I needed to call back. Before I called back, I searched the number and got this site. In order to be cautious, I did call Chase to inquire about the card, but I called the number on the back of the card - NOT 888-373-1969. The real Chase representative said that there was no activity on the card and no alerts on any of my accounts.I called 888-373-1969 back and listened to a very good imitation of Chase's automated system that only provided an option to be removed from telemarketing calls. It asked me to press one, which I did not do. The call eventually ended. A few minutes later, I received the FOUR additional attempts from 888-373-1969. This is TELLTALE evidence that this is a scam telemarketing call. My callback confirmed that my number was real and justified their repeated attempts to reach me.If you call back, it will sound a lot like Chase. Don't call this number. Call a number on the back of your card and find out if there is anything to be concerned about. 99% that this is NOT Chase.
