Most new scams are just variations on old scams and this one is no exception. Many people, particular older Americans are receiving telephone calls from their medical insurance companies informing them that they will be receiving new identification cards for new expanded benefits which will now include dental and vision coverage. Then comes the kicker. All the company needs, you are told is just some bank account information for confirmation. If you give the information to the scammer, you are giving them the keys to your bank account and making yourself a victim of identity theft.
Never give information to anyone over the phone whom you have not called because you can never be sure who they are. Also, consider why anyone, such as this person, would even require such information. There is no reason your medical insurer would need your bank account information. Whenever you have any question as to whether such a call is legitimate, merely call the number for the company with which you do business at a number that you know is legitimate and you can confirm whether or not the initial call was a scam.
