Calls about documents for a pre-recorded person's name. They have information on you, but it might be a bit off. Don't give them anything they can use. They might threaten you with a warrant, charges of fraud or federal crime. They are most likely calling about a loan with details that don't sound entirely familiar. Because they aren't. they sometimes identify themselves as RPFS (could be RPSS, OPSS, hard to tell what she is saying), but usually just give a random name. They use multiple numbers. Report these calls to the FTC on the ftc.gov website. Give all the details you can. Uploading the calls here may not be a good idea because the calls are personalized with a pre-recorded name.

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.

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.
