Have you ever received a spam or scam phone call from your own number? This is a version of spoofing telephone numbers known as ‘neighbor spoofing’, ‘neighborhood spoofing’, or ‘neighbour spoofing’ if you are outside the U.S.. Neighbor spoofing involves the scammers spoofing telephone numbers such that it appears you are receiving a telephone call from nearby (that’s the ‘neighbor’ in ‘neighbor spoofing’) – and sometimes their computer will accidentally spoof your own number.
