About the FTC data

These are unverified consumer complaints, not findings of wrongdoing. Caller ID can be spoofed, so a reported number may not identify the actual caller.

Scam suspicion
Unknown United States · +1
One of my friend had posted an ad in an online platform. She had a collection of old coins and wanted to sell them for 3000 USD. She got a whatsapp message from this number (5172732890). Introduced himself as John Hunter from USA. The advertisement was posted on a local platform and not in united states. He texted that he want to purchase coins from her. He asked whether she had any more coins. She said yes and He said he want them all. She sent the pics of some more coins. He asked for the price and she said an amount around 4000 USD. He agreed without any negotiation. He then asked her to open an account in 'Neteller' to transfer the money. I felt like a scam and called that number from my cellphone. It was not answering even after several attempts. Neither the call going to a voicemail. She texted whether she can talk to him over the phone. He said only after opening the account. She installed the Neteller app. Then he asked her to deposit around 100 usd into her account to verify her account. I called Neteller to ask about this and the customer care girl told me no need to deposit that much amount to verify the account. just 5-6 USD could do that. In the mean time, that guy send us some family photos saying that its his family. I asked my friend to message him whether he can send us pics of his coin collection. He send a picture which was nicely arranged and showcased. It looked like a museum and not like a personal collection. I searched for that image in the internet and found that exactly same image from one of the national museum's website in India. This guy just downloaded that picture and send us saying that its his collection. My friend don't have any much knowledge about internet and internet scams. She approached me because she don't know to deal with the online transactions.

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.
