Number isn't dead, it's now making its rounds to Hawaii residents. Got two calls and messages from this number at my parents' house, BUT the message asks to be called back at 530-208-0695. Too bad the local IRS office here isn't taking calls for complaints. I agree that this scam will easily take advantage of the elderly. Be careful, people.
I received a message from this number claiming to be an IRS Agent asking me to call him back. Searched the IRS website and saw an IRS warning about IRS call scams. IRS said it will contact you via mail if you have tax problems not via phone. I am posting the IRS link below for everyone's information. Please let people know about this scam and report the number to www.ftc.gov
Had a call from this number calling to be working with the IRS. Wanted my exact location so they could send local law enforcement to collect me. Started screaming at me that they could trace my call. Person did not have anything but my name.
