I received calls from this number on 1-30-16 and 2-1-16. I don't answer phone calls from numbers I don't recognize, so this message was left on my voicemail: "This call is officially a final notice from IRS, Internal Revenue Services. The reason for this call is to inform you that IRS is filing a lawsuit against you. To get more information about this case file, please call immediately on our department number: 206-899-8562."
I did not bother calling back since it is obviously a scam. First clues: Note that the message says the call is from "IRS, Internal Revenue Services" -- if you're not listening carefully, you may miss the obvious mistakes: (1) The government office they're pretending to be is the US Treasury Department's Internal Revenue Service (NOT Internal Revenue Services), (2) We commonly refer to this office as "The IRS" (rather than just "IRS"), and (3) With all of the media attention regarding scams, we should all know by now that the IRS does not make threatening/harassing telephone calls (see BigA's 2-1-16 post, above, for related specifics about how the IRS contacts people).
To report this (or other) IRS-related scams to the Treasury Inspector General for Tax Administration (TIGTA) go to https://www.treasury.gov/tigta/contact_report_scam.shtml.
To officially report scams to the TIGTA, you will need to give the date of the incident, how you were contacted (email, fax, mail, mobile phone, landline, or in person), how the impersonator identified him/herself, the phone number from which they contacted you, the number(s) you were directed to call, and whether you suffered any financial loss. You must also provide your name and contact info, in case they need additional info. Note that you will also create a personal PIN number, which you should also write down/remember. They strongly advise that, "In the event a TIGTA Special Agent contacts you about your complaint, please request the personalized PIN for confirmation. Please take caution if the person does not know the PIN."
The TIGTA reporting page also has links to a press release describing Impersonation scams and to a list of some of the suspected phone numbers used by these scammers. I presume that these phone numbers are those provided by people who actually take the time to submit a report -- more reason for all of us to follow through on filing an official report, in addition to posting our experiences on whocallsme.com and other such websites.
