I don't know if it is a real phone number from Chase or not. But something is real. It's an automated call from Chase Bank's Fraud Prevention Department. And it's real. It is not a scam! However, I don't (and you should never) respond to automated calls like this or the email I also received from them at the same time. I called Chase Bank directly (and so should you) so I know who I'm calling and was told that in fact, someone had tried to use my debit card (or at least the card number) to the tune of almost $700.00 in three attempted transactions with PayPal and Wal-Mart! Hell, I had only like $34.00 in the account. But they told me that the transactions didn't go through as they didn't authorize them. I mean hell, you know, insufficient funds, you know?!? So they cancelled my card and are sending me a new one. Now, to be smart, don't ever respond directly to an automated call or email because those are too easy to fake. Instead, call Chase Bank directly and ask to speak with their Fraud Prevention Department. Even if you don't have an account with them, do it. Only they can tell you if they contacted you about some suspected fraud or not. In my case, everything was legit.
