A 945 number on your screen can still be a scam, because caller ID is easy to fake.

  1. Let an unknown call go to voicemail. A real caller leaves a message; a robocaller usually does not.
  2. Look the number up with the box above before you call back, because calling back tells a robocaller your line is live.
  3. Hang up on anyone who wants gift cards, crypto or a wire transfer, or asks you to read out a code that was just texted to you.
  4. Report unwanted robocalls at reportfraud.ftc.gov, or paste a suspicious message into our free scam checker.
