Caller name: IRS
Caller type: Scammer/Fraudster
An elderly lady friend gave me the following information, so I am writing this on her behalf. At 5:50 AM, California time on Wednesday, 1/20/16 my friend received a call from "The IRS" from phone # (202) 310-8534. She didn't get to the phone in time, but the caller left a message - "This is the IRS, you owe us money and we are pressing charges against you, call us back at (202) 310-8534."
My friend was astute enough to know it was a scam and did not call back.
