AT&T Tax Scam (IRS,CRA)

I have received 2 robocalls from this scammer, last one at 1430 today. I called back to see what I could find out about them and there are 2 people answering the phone, one male and one female. Both are ESL persons. Several calls the woman hung up on me when I pressed her for information, something the real IRS would never do. The message left on my voicemail is as follows: Filing a lawsuit against you and arrest warrant has been released on your name to get more information about this case file and arrest warrant from federal database please call immediately after the IVR recording at our headquarters number that is 510-851-0127. I repeat 510-851-0127. Internal revenue service agent is waiting for your call back. The carrier for this phone number is H2O wireless or New Cingular Wireless PCS, LLC. My caller ID says the number is based out of Hayward, CA with the name Lee Wood. Both persons provide fake names depending on how many times you call back (I called 6 times). They were told to remove my phone # from the call list and still called back. They claim to be in a satellite office of the IRS in a call center and give you bogus employee numbers - same person's voice different numbers. The last time I called I told them the phone # they were calling belongs to a minor child so stop calling, they called again. In one call I played along making up info in an attempt to get more information - phone # given was for another IRS scam line. The address they provided was the White House in Washington DC. I pressed them and said that 510 is a CA number- changed story to a call center. According to http://www.whycall.me/510-861-0127.html, the exchange 861 is managed by BLUE LICENSES HOLDING, LLC. The number is currently on switch number SNTDCAUJCM9 (switch is a technical specification, provided here for phone hobbyists)

Whose Number Is This in United States?

With over 105 billion unwanted robocalls made in the US annually, receiving calls from unknown numbers is a daily challenge for Americans. Whether it's a missed call from an unfamiliar area code, potential IRS scam, or suspicious telemarketer, our community-powered phone lookup service helps you identify who's calling before you pick up.

Our reverse phone lookup service allows American users to search for phone numbers and access reports from other community members. By sharing experiences and reporting spam or robocalls, we create a safer telecommunications environment for everyone across all 50 states.

Common Spam Call Types
in United States

  • IRS impersonation calls demanding immediate payment
  • Tech support scams claiming your computer has a virus
  • Social Security scams threatening arrest or suspension
  • Fake package delivery texts from USPS or Amazon

How to Identify Scam
Numbers

  • Caller claims urgency or threatens consequences
  • Requests personal info, PINs, or OTP codes
  • Offers that sound too good to be true
  • Unknown numbers calling repeatedly

Are Unknown Calls Always
Dangerous?

Not all unknown calls are harmful. Many legitimate callers include:

  • Delivery services confirming orders
  • Banks calling for legitimate verification
  • Medical offices, pharmacies, or hospitals
Pro Tip
Register your number on the National Do Not Call Registry at donotcall.gov. The FCC requires carriers to use STIR/SHAKEN technology to verify caller IDs. The IRS never calls demanding immediate payment - they always send a bill by mail first. Report scams to ReportFraud.ftc.gov.
