Question 1

How do I find out who called me?

Accepted Answer

Start with the area code to see where a number is registered, search the full number online, and check our community-reported numbers. Caller ID can be spoofed, so the displayed number is not proof of identity.

Question 2

What is area-code spoofing?

Accepted Answer

Spoofing lets a caller make any number appear on your caller ID — often one in your own area code ('neighbor spoofing') to seem trustworthy. The real caller can be anywhere in the world.

Question 3

How do I stop spam calls?

Accepted Answer

Don't answer unknown numbers, block persistent callers, register at donotcall.gov, turn on your carrier's spam filtering, use a call-blocking app, and report unwanted calls at reportfraud.ftc.gov.
