I received a VALID voice call from this number sending me a security code I needed to log into a website. The number (646) 760-4385 also sends the same type of message. Unfortunately, my Ooma service blocked the call b/c the numbers must be on one of their blacklists. Had to bring down my call blocking feature to receive the calls.
Legitimate call. Verification code from my physician so I could do online check in.
Medical appointment verification... asking you to complete details and cofirm drs upcoming appointment. Scary since after you complete details, they call to give a code... that is when I decided to hang up but still concerned
