TL;DR: Synthetic identity fraud now costs businesses an estimated $20-40 billion globally each year, with U.S. lenders facing $3.3 billion in exposure from new-account abuse through 2024, according to iProov. The structural problem is that fabricated identities remove the victim from the detection loop, so onboarding verification has to do the work that reporting and recovery never can.

Editorial analysis by NHI Mgmt Group, based on content published by iProov: “Synthetic Identity Fraud: The Invisible Victim Problem and How to Solve It”.

By the numbers:

  • U.S. lenders faced $3.3 billion in exposure from synthetic identities tied to new accounts through 2024, according to iProov.
  • 44% of organizations now rank synthetic identity fraud as their top-tracked fraud type, according to iProov.

Key questions

Q: What fails when synthetic identity fraud gets past onboarding?

A: The core failure is that the system has already accepted a fabricated person as real, so every downstream control starts from a false identity.

Q: Why do synthetic identities and identity theft create such high risk in new account origination?

A: They defeat traditional checks because the profile can look consistent across multiple data sources while still being fabricated.

Q: What are the signs that onboarding verification is too weak for synthetic identity risk?

A: Warning signs include heavy reliance on data matching, thin or unusually clean identity histories, rapid account creation, and controls that stop at document checks.

Practitioner guidance

  • Tighten onboarding proofing thresholds Require stronger identity proofing for high-risk onboarding paths where fabricated identities can enter through remote or low-friction enrolment flows.
  • Add genuine presence verification Use liveness and session-integrity checks so account creation depends on a real, physically present person rather than a replayed image or deepfake.
  • Review fraud controls at issuance time Shift control design toward the point where the identity is first trusted, because post-onboarding anomaly monitoring cannot recover a fabricated enrolment.

Bottom line: Synthetic identity fraud exploits a structural gap in onboarding because fabricated people can satisfy checks that were never designed to prove real-world presence.

Identity proofing breaks when the enrollee is fictional: Synthetic identity fraud is not a better version of identity theft, it is a different governance failure. The control problem is that onboarding systems are asked to validate an identity that has no real-world owner to monitor, contest, or recover the loss. For practitioners, the implication is that proofing must establish presence, not just consistency, before trust is extended.

A few things that frame the scale:

  • Sumsub's Identity Fraud Report 2025-2026 recorded an overall fraud rate of 2.2% across verified accounts in 2025, and multi-step identity fraud rose from 10% of attacks in 2024 to 28% in 2025.

A question worth separating out:

Q: How should organisations respond when remote onboarding can be abused by fabricated identities?

A: They should raise assurance at the first trust decision, not after the account is live. That means stronger proofing for remote enrolment, liveness and session-integrity checks, and consistent standards across customer and workforce onboarding paths where the same identity risk exists.
