Phone number portability, while beneficial for consumer convenience by allowing users to retain their numbers when switching carriers, poses significant fraud risks such as SIM swapping, where attackers trick carriers into transferring a victim's number to a SIM they control, enabling unauthorized access to sensitive accounts. Traditional verification methods relying on OTPs are inadequate if a number is compromised, necessitating advanced real-time checks on phone status, carrier changes, and potential porting attempts to detect suspicious activities. Didit offers a modular, AI-native platform that integrates these composable phone and email verification checks into existing workflows, providing robust defense against sophisticated fraud through features like carrier change detection, disposable number identification, and risk scoring. By combining these checks with additional identity verification tools such as biometric authentication, device intelligence, and AML screening, businesses can create dynamic, multi-layered fraud prevention strategies that adapt to evolving threats while minimizing inconvenience for legitimate users. Through its flexible architecture, free core KYC, and global reach, Didit empowers businesses to efficiently combat fraud on a scalable level, ensuring greater security for their users.
