How the check works
Fake Number Check detects more than 100,000 known invalid phone numbers in real time, and the list updates automatically as we find new ones. It also catches area codes and prefixes that don’t exist.
A number identified as fake is very unlikely to be able to receive a call or text. See the top 10 fake phone numbers for the ones we find most often.
