Duplicate Account Detection

Duplicate account detection is the process of identifying and preventing multiple accounts created by the same individual or entity within a system. Fraudsters often create duplicate or fake accounts to exploit promotional offers, bypass limits, launder money, or commit identity fraud. Even in legitimate cases, duplicate records can lead to operational inefficiencies, inaccurate reporting, and compliance risks.This process is critical for banks, fintechs, e-commerce platforms, gaming providers, and telecom companies where customer accounts are tied to sensitive financial or personal data. Detection methods typically include identity verification checks, biometric matching, device fingerprinting, and behavioral analytics to spot overlaps across accounts. Automated solutions powered by AI can flag suspicious duplication in real time, reducing fraud losses and improving data quality. Effective duplicate account detection also supports compliance with KYC and AML obligations by ensuring customer records remain unique and verifiable.
