We received a message on our answering machine from this number, stating it was the Internal Revenue and they were going to sue us. My 12 year old son heard the message and came running to find me in the house and was almost hysterical, being afraid that we were being sued. I called the number back and got a message stating "The person you are trying to reach is not available at this time". I have reported this to our Attorney General.

Got a call from this number.  I did not answer it.  Kind of wish I did now.  If everyone else is being told it is the IRS  as I am Canadian and the IRS have no reason to come after me and no jurisdiction over me.

The scammers are generally pretty dumb when it comes to political geography.  Ignore and block the calls.

Same as everyone else. They claim I am going to be sued and have wages garnished etc. Don't give them any info, don't even call back.
