Toll-Free Number Scam suspicion

This is Allen Dawson and A*sociates's number. They called my number requesting to speak to someone else. Told the lady its a wrong number and she kept going on like I was lying so i cut off the line. She called back with a No call number and I let it go to Voice mail which was where i got the company's name when someone picked it. Told them i m on a do not call list and they should NEVER call me again. It's 100% Scam.

Verizon Tax Scam (IRS,CRA)

I got a call from this number telling me pretty much that I had taxes filled out from 2014 to 2017 that had been filled wrong and that I had a law suit against me from the IRS and that they were going to freeze all my accounts and collect my vehicles and house if the matter wasn't dealt with quickly, the girl that I talked to even said that I could even lose my citizenship and be deported and that I needed to act quickly because if I didn't, there would be a warrant for my arrest sent out to local police enforcement. Needless to say I searched the number and saw that I wasn't the only one who has had a call of this nature and I found it kind of fishy, I did mentioned to the person on the phone that I had seen their number coming up as a fraud attempt, and that if it was a real thing, I would contact the IRS directly with all the information she gave me(Case numbers and badges).

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.

Frequently Asked Question

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.

The USA country code is +1, shared with Canada and other North American countries under the NANP (North American Numbering Plan). US numbers are formatted as +1 (XXX) XXX-XXXX, where XXX is the area code. For example, a New York number (212) 555-1234 becomes +1-212-555-1234 internationally.

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.
