I got the same text and I found it very disturbing that I got a disconnected number message when i called the number as the text instructs.

I got the same message. I called Chase at their number listed on my account page and they said that they did not send that message, to ignore it, and they would report it to their security division.   Another call checking site shows about 5 of these calls this evening to other users.  Be careful everyone!!!

"Message from CHASE. Call 1-877-669-4027 regarding your debit card starting in 511182. Thank You."
