I also received an automated call asking me to call 877-828-5743, and they gave me an 8 digit PIN to enter. The reason for this is so that they DO NOT have to ask for personal info such as SSN or DOB. This 8-digit number identifies you as the person they're trying to reach without having divulge personal info. So, if they call you and ask for SSN and DOB, just hang up the phone! I called UHC by calling the number on the back of my insurance card and the representative told me that the number was their coordination of benefits department just calling to check if I had additional forms of insurance. She said she would update my info directly, and I could disregard the phone calls. I have not received another one since then. So, I guess the number is legit, HOWEVER, I think the number is also being used by a phishing scam (you know it is possible to spoof numbers.. there is a computer program that can trick your caller ID into displaying any phone number that is entered into the program). The other comments say that they there was a live operator asking for SSN and DOB, but I was never asked for that personal info. The UHC rep told me that they would NEVER ask for that personal info over the phone, unless YOU call THEM. That is why they give you the 8-digit PIN to enter instead of entering your personal info. So, if someone is calling you and asking to call that number and give them your SSN and DOB, that is a scam!
Keep getting calls from unknown number that calls 2 hrs apart. I finally answered the phone and found that they said they were United Health Care. The woman wanted my date of birth and ss#. Hung up on her. They are still calling... My number is unpublished so I don't understand why they're calling. My question is, why would you call me to ask for my private info? This is a scam, fraud, both.
I just received the same call I didn't answer just googled the number but if you are saying that it is from united health care then that would make sense because that is the name of my new medical insurance..
