Good Questions: Caller ID, Halloween Candy & Wisdom Teeth
MINNEAPOLIS (WCCO) -- Sandy asks: Why does caller ID sometimes show your own phone number?
It is called "spoofing," and the Federal Communications Commission (FCC) says it is against the law.
It is not hard to do with today's technology. It is a common practice among illegal telemarketers and fraudsters who believe a person's curiosity will get them to pick up the phone. If it happens to the point of annoyance, you can file complaint with the FCC.
