Tax Scam (IRS,CRA)
Unknown United States · +1
Bunch of third-world slimeball Indians (always Indian accents) saying they are from the IRS and that I owe them money. They called me and left no message so I called them back. I would not give them my name so they hung up. These losers are probably VPN-ing from some s--thole mud hut in India for 20 hours per day. I told them that they were TOO STUPID to even scam anyone the way they are working it.

This is scam call pretending to be Direct TV. Don't believe it, it originates from Bangladesh, India . It starts as a text message claiming there is a 50% off promotion with a promotion code of ; EBAY. The text phone number is spoofed and sent on Skype. They will list an account number for Direct TV and it not your's. Don't fall for this cr*p.

Scam suspicion
Toll-Free Number United States · +1
I received a call from Legal Claim Services. They told me they have been trying to serve me at my home and that since they have been unsuccessful they wanted to serve me at my workplace. They gave me a 888 number to call and a case file. I call and spoke to some lady who then transferred me to William Baker, from Western A*set Company. He claims he is not a debt collector but that once I am served he can no longer help me get a reduction of a credit card debt that was from 2010. I asked for debt validation and was told they already sent me several notices. I haven't received anything. I also told them the statue of limitations has expired on a credit card debt from 2010. I called back to get an address so I can send a debt validation request and he refuse to give it to me without me giving my name and then put me on hold and subsequently hung up on me.

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.

Everything you need to know about phone number lookup in United States

Enter the US phone number in WhoseNo's search box. Our free reverse lookup searches millions of records to identify the caller, show carrier information (AT&T, Verizon, T-Mobile), display user reports, and reveal if the number has been reported as spam or robocall.

Unlike some countries, US phone numbers aren't assigned to specific carriers by prefix. Due to number portability, users can switch carriers while keeping their number. Our lookup tool queries carrier databases to identify the current service provider for any US number.
