received a call, phone # 303-270-1566, claiming to be from xfinity. The automated call advised me that I am eligible for a 40% discount and to press 1, which I did. I was forwarded to phone# 303-372-4756. I became suspicious when the woman I talked to wanted me to verify my e-mail address, which she should know since I am a customer of xfinity.

Caller claimed to be calling from Microsoft Windows and wanted to ‘help’ me fix the nonexistent problem with my computer. He was very insistent and when I said no and hung up he called back twice. He offered me phone numbers to call to verify his call and just wanted my computer ID number and he would help me find it. He called once more (total of 4calls) but I didn’t bother to answer.

Whose Number Is This in United States?

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.
