Tax Scam (IRS,CRA)
T-Mobile United States · +1
Called my husbands phone and left robot voicemail claiming that if he didn’t call them back ASAP they were sending the cops to our house to have arrested. He called them back and a women answered and when he asked who she was she hung up. I called back twice, no answer. Called a third time and a man answered the phone and said Internal Revenue Service and I asked him what I was being arrested for and he said for money owed for mistakes on my taxes and I said that’s weird because I didn’t even file taxes this year and the IRS doesn’t make personal phone calls to people making threats. Have a good day and he hung up on me.

This person called and blocked their number. She left a message wanting someone that had a first name of Aleshia but with my last name. I don't know an Alshesia. She then said I had been warned that a complaint had been filed about Aleshia and I better call 877-839-0052. I did not call the 877 number as the entire call looks very suspicious and when I Googled the number others said the same thing.

Whose Number Is This in United States?

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.
