CALLER’S NUMBER: +1 (747) 755-6174 LATA: 730 OCN: 707H CALLER ID: NORTHRIDGE CA PHONE PROVIDER: ONVOY, LLC - CA LAST PORT DATE: 2019-03-03 16:01:11 LRN: 2134930993 RATE CENTER: LSAN DA 07 STATE: CA This call is from an “UNKNOWN UTILITY SCAM” that is coming from a virtual phone number. They will call from various phone numbers, and phone type. According to my research program such as this caller is unlikely because government do not “advertise their services by calling or emailing people randomly or knocking on doors. If you get a message about an energy assistance program, don’t sign up for it or give out any personal information. Instead, visit Benefits.gov to search for legitimate energy assistance programs in your state. You can also check out your utility company’s website to see if it offers any programs to help you with your bills.”

Claims to be spectrum on the vm. Gives a completely different number for you to call back. I have NEVER had any dealings with Spectrum so they have absolutely no reason to call me. I know this is some hackers and fraud activity because of something else though so they used an app to change the number they're calling me from and pushed in the fake vm.

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.
