The same IRS scam using a new spoofed number. Total idiots, called at 6:00 a.m.  Who could ever think the IRS would call at that hour! And the CID read WIRELESS CALLER. Yeah, the IRS now has no office phones! Blocked this number too.

There are numerous telephone and email scams in which individuals claim to be employees of the Treasury Department. These scammers often state that they are from the “Department of Legal Affairs,” offer grant money in exchange for you wiring a small payment, or threaten to arrest you within a short period of time unless payment is made. Do not provide personal information or payment to these individuals.  Their actions are crimes under Titles 18 and 31 of the United States Code, and the Treasury Office of Inspector General is working to stop them.

If they claim to be from Treasury, report  it to OIGCounsel@oig.treas.gov with a description.  If it was a phone contact, include:
the exact date and time that you received the call(s)
the phone number of the caller
the geographic location and time zone where you received the call
a description of the communication.

If they claim to be from the Internal Revenue Service (IRS) or it is about taxes, report it to the Treasury Inspector General for Tax Administration at:

IRS scam recording. Which they never call,etc. Always a notice in mail and then you call them. Fifth number that has tried this.

Same - but 5 a.m. call here.  Added to auto-reject list.  The crowd-sourced technology exists to shut these people down so easily, just like spam filtering in your email, but the phone companies refuse to do it because they make money off of every phone number the sell.
