I too received a call from this number. I called backed, let them know I was recording the call, asked them for their 1-800 number and badge number and they hung up on me. They did identify themselves as the IRS.
I also received the same number. When I called them the number is disconnected. It appears to be a cell number. I was so upset over the call and called my financial consultants and said IRS does not function in the way this caller is handling issue. Please be aware. This person had my addresss and full name. Please report them.
