This person has called me from multiple phone numbers that I have blocked after asking them not to call again. They always indicate they are from the local police or firefighters pac here in Colorado and ask for donations. I donated $15 one time and they called me back in two weeks and said they never got my donation even though I had bank proof it went through. While this number might fall under donations, I am marking it as scam suspicion because of the multiple different numbers used and the refusal to remove my number from their database.

According to my call back the name for this research company is Venten Data, but on December of 2023 it was the Height Research and National Public Opinion Firm. Though on one data base this number is registered to [REDACTED] located in [REDACTED], Brookhaven, GA. This number also has a negative user reputation across a few reverse number lookup sites, and appears to be a virtual phone managed by is Level 3 Communications in Miami, FL. I have no idea on how they were able to obtain my number since I’m on the FTC do not call list. I have never have given my number to any such companies nor do I consent to being contacted.

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.
