Verizon Scam suspicion

Number left a message claiming to be IRS with warrants and have a number to call back. Number shows as Washington DC. I’ve had other numbers affiliated calling with several different numbers showing as the United States. I block them one by one. The IRS would never not notify you by mail or in person regarding a descrepency. Block block block this is a scam

Your report is anonymous. We never share your personal information.

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.

Yes, WhoseNo provides completely free reverse phone lookup for all US numbers including AT&T, Verizon, T-Mobile, and regional carrier mobiles, as well as landlines across all 50 states. No registration or payment is required to search numbers or view results.

Search the number on WhoseNo and submit a report describing the call. For serious fraud, report to the FTC at ReportFraud.ftc.gov, file a complaint with the FCC, or register your number on the National Do Not Call Registry at donotcall.gov. You can also report to your phone carrier.
