If you want to know if the numbers calling you are a scam, do what I do. Let the phone ring and let it go to voice mail. More than likely they won't leave a voice mail. Call the number back. I found out by doing this that most or all of the numbers are disconnected or no longer in service, and then the message will tell you to check the number that you're calling to make sure it's correct. That is someone and/or some group trying to scam you.
