Synthetic identity fraud is a highly sophisticated financial crime where a bad actor combines real, stolen information (such as a legitimate government ID number) with fabricated details (like a fake name, address, or birthdate) to create a completely new, nonexistent persona.
How It Bypasses Traditional Checks
Because a core part of the identity is real, synthetic identities can often pass basic, legacy KYC and KYM checks. Fraudsters use these fake identities to build credit histories slowly over time. They eventually open merchant accounts or take out large loans before "busting out"—maxing out the credit lines and vanishing with the funds.
Detecting Synthetic Fraud with Onlayer
Simple watchlist checks cannot catch synthetic identities because the names are fake. Onlayer utilizes advanced entity correlation and fuzzy logic to uncover inconsistencies in digital footprints. By mapping merchant presence and identifying up to 3x more fraud risk signals than internal sources alone, Onlayer exposes these complex impersonation risks instantly during the onboarding process.
