Who is this?
A woman left a voicemail identifying herself as Latavia. She said she was trying to contact me and listed suspiciously short business hours, no company name, and provided a callback number different from the number that called me. The number she called me turned out the be spoofed. The spoofed number belongs to a local domestic violence resource center, but I confirmed they did not attempt to contact me. When I searched the 877 number, all the google search results were related to debt collection scams. Definitely a scam.

- 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.
