Each prefix, or block of 1,000 numbers inside it, is also handed to a carrier. A number keeps its digits when its owner switches carrier, so the prefix no longer tells you who carries it today. Our free carrier lookup shows which carrier a 771 number is on now.

  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.
