Neighbor spoofing: why you're getting calls from your own area code

If your phone keeps showing calls from your own area code — or a number almost identical to yours — that's neighbor spoofing. The displayed number is fake, and the real caller is usually a robocall operation that can be anywhere.

How neighbor spoofing works

Caller ID was never built to be secure — the calling party supplies the number that's displayed, and VoIP lets it be set to anything. Robocallers generate a caller-ID number sharing your area code and often your 3-digit prefix, so the call looks like a neighbor and you're more likely to answer. Because the number is invented, blocking it rarely helps for long.

How to stop spoofed and spam calls

  • Let unknown numbers go to voicemail.
  • Turn on your carrier's free spam filtering.
  • Use a call-blocking app or "silence unknown callers".
  • Register at donotcall.gov and report calls at reportfraud.ftc.gov.
