430 started in 2003 as an overlay on 903, and its ground has not changed since.

  1. 2003

    430 starts on February 15, 2003, as an overlay on 903: new numbers on the same ground.

A 430 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.
