SIM Swap fraud is orchestrated by an attacker first gathering enough relevant details about a person's identity, such as their date of birth, address, a driving license number etc. The attacker then use these details to present themselves as the legitimate owner of a phone number to the Mobile Network Operator. If they succeed, they can then request a new SIM card be issued for the phone number to them. With this new SIM card in their possession, they will be able to impersonate the real owner of the mobile phone number. Active SIM Check by tru.ID enables developers to prevent SIM Swap fraud by identifying changes to a user's active SIM within the past 7 days.
