Why Fraud Prevention is Key to the Auto Market

Updated June 1, 2026

Auto fraud is surging, and the shift from paper to digital is raising the stakes for everyone involved. The rapid migration to electronic documents for automotive transactions brings speed and convenience, but it also opens new attack surfaces. Simple e-signatures alone don't cut it.

Regulatory requirements have historically blocked the use of e-sign throughout the vehicle transfer process. In most cases, regulators have required either a wet-ink signature or a higher level of identity proofing, specifically IAL2, to execute documents electronically, including odometer disclosures, title documents, and others.

Any business that touches vehicle title and registration, including dealerships, lenders, insurance carriers, salvage operators, and tow services, is handling documents that fraud actors actively target. Going electronic isn't just about convenience. It's about closing the attack surface.

Key takeaways

• Rising fraud risk: The shift to digital auto documents increases exposure to odometer fraud, title fraud, and forged signatures.
• IAL2 standard: NIST IAL2 identity proofing is the high-security benchmark required for critical electronic documents like odometer disclosures.
• Regulatory guidance: 2024 updates from NHTSA and AAMVA clarify when IAL2 is required versus standard e-signatures.
• Business benefits: Implementing robust identity proofing reduces costs, ensures legal compliance, and builds trust across the transaction chain.
• Remote operations: Secure digital verification allows dealerships and lenders to expand their market reach without sacrificing fraud controls.

The fraud risks

Auto fraud costs consumers and businesses an estimated $4.5 billion annually in the U.S. alone. IAL2-compliant verification uses biometric identity matching, passive liveness detection, and a tamper-evident cryptographic audit record to ensure the person signing is who they claim to be. The fraud risks across these workflows are real and varied:

Common tactics

• Odometer fraud: Altering mileage readings to inflate a vehicle's resale value
• Title fraud: Forging or altering a vehicle's title or registration to conceal accident history or salvage status
• Forged signatures: Executing documents on behalf of someone who never authorized the transaction
• Misrepresentation: Hiding prior damage, rental use, or lemon law history from buyers
• Insurance fraud: Staging accidents or filing false claims to collect payouts on vehicles that aren't worth repairing or reselling
• Undisclosed fees and charges: Inflating the total purchase price with hidden add-ons that were never agreed to by the buyer

What you can do

• Require IAL2 identity proofing before any electronic document is executed
• Adopt an electronic registration and title (ERT) system that enforces verified identity at every signature touchpoint
• Deploy a verification solution like Proof Identify with no IT integration required
• Pair identity proofing with advanced fraud detection like Proof Defend for layered protection

Certain documents, like the odometer disclosure, are critical to the integrity of the transaction. Tamper with them, and the entire sale is compromised. That's exactly why regulators have imposed higher security standards on them. Every document in the chain is a potential point of exploitation when identity isn't verified. When fraud slips through, buyers end up overpaying for vehicles that need costly repairs or replacement far sooner than expected.

In 2024, the National Highway Traffic Safety Administration (NHTSA) and the American Association of Motor Vehicle Administrators (AAMVA) separately issued clarification and guidance regarding IAL2 and electronic document execution.

The key takeaway: while states continue to roll out electronic registration and title (ERT) systems, IAL2 is not required when a physical document is uploaded to a digital platform. A physical document that is uploaded can be signed using regular e-sign.

The benefits of fraud prevention

Convenience is welcome, but skipping IAL2 verification or identity proofing altogether raises fraud risk significantly. For states and businesses alike, onboarding an identity proofing solution carries meaningful benefits, with fraud protection being chief among them:

Reduced fraud

‍ IAL2 authentication significantly reduces the risk of fraudulently executed documents by ensuring that only authorized and verified individuals can electronically sign them. This protects the integrity of essential items like the odometer disclosure, a document no vehicle sale can close without. When that single document is secured, the overall transaction is secured with it.

Legal compliance

‍Motor vehicle policy is set by each state, in some cases at the county level. By meeting the requirements set by IAL2, businesses and individuals can ensure they are in compliance with higher execution requirements from state to state.

Remote authentication

‍ IAL2 doesn't require customers to appear in person. That means you can verify identities, execute compliant documents, and close transactions with customers anywhere, without sacrificing the fraud controls that protect both parties.

Lower costs

‍For businesses serving customers beyond their physical footprint, going electronic eliminates the costs and delays of overnighting documents and chasing customers to sign and return them.

Trust and confidence

‍When you require identity proofing, every party in the transaction, including sellers, buyers, lenders, and regulators, has a verified record to stand behind. When disputes arise, identity-backed records become evidence, giving every party a defensible trail that stands up to scrutiny.

Regulators are relaxing requirements for convenience. That doesn't mean the fraud risk has gone down; it means the burden just shifted to you.

Why fraud prevention still matters for auto transactions

While AAMVA acknowledges the convenience a change in policy may bring about, they also recommend that state regulators take full advantage of available technology to fight fraud.

The risk doesn't stop at the dealership lot. Lenders, insurance carriers, salvage operators, and tow services all handle documents where a single forged signature or concealed defect, from undisclosed warranty status to hidden accident history, can expose the entire transaction chain to liability. Business owners who recognize the value of preventing fraud and avoiding costly losses should continue to require identity proofing before executing an electronic document.
