WHY VERIFY ACCOUNTS

Why bank account verification matters

Bank account verification has become an essential part of modern financial workflows and can support regulatory compliance. Organisations need confidence that payments are being sent to valid accounts owned by the intended customer, supplier or beneficiary.

Verifying accounts up front turns a manual, judgement-based check into a consistent, auditable control – helping reduce fraud losses and build trust with the customers, suppliers and beneficiaries on the other end of the payment.

Traditional verification approaches often rely on historic or aggregated information captured at a single point in time. As payments become faster and fraud becomes more sophisticated, organisations increasingly need live account information, intelligent fraud signals and real-time decisioning.

FRAUD RISK POINTS

Where fraud enters the payments customer lifecycle

Fraud risk does not end once an account has been verified. It evolves throughout the customer relationship, creating new opportunities for fraudsters whenever account details change or payments are made. Applying account verification and related controls, such as ownership verification and fraud signals, at the moments where risk is highest – during onboarding, when account details change and before higher-value or higher-risk payments are released – helps organisations identify fraud risks before money moves.

Onboarding

Onboarding

When a new customer, supplier or beneficiary is added, organisations need confidence that the account is genuine and belongs to the intended party. Synthetic identities, fake suppliers and fraudulent account details often enter payment ecosystems at this stage. Real-time account and ownership verification can identify fraudulent accounts before they are trusted.

Account changes

Account changes

Updating existing details is one of the highest-risk moments in the payments lifecycle. Social engineering and account takeover frequently occur when fraudsters persuade organisations to change legitimate account details, with high volumes of fraud originating at this point. Re-verifying account ownership before changes are accepted helps prevent payments from being redirected to fraudulent accounts.

Payments and disbursements

Payments and disbursements

As payments become faster, the opportunity to recover funds after they have been sent is disappearing. A final verification check immediately before a transaction is executed provides one last opportunity to confirm account details, identify fraud risks and prevent suspicious transactions before execution.

WHY CHOOSE LSEG

Why organisations choose LSEG Risk Intelligence

Modern payment fraud requires more than a basic account check. Organisations need current account information, ownership insight and fraud signals that can be applied throughout the payments lifecycle.

Reduce payment risk

Current account status helps identify accounts have recently closed, changed hands or been frozen before payments are released.

Make decisions faster

Real-time account verification verifies account status at the point of onboarding, account change or payment initiation, with responses typically returned in less than one second reducing unnecessary delays.

Know who you’re paying

Account ownership verification confirms that the account belongs to the intended customer, supplier or beneficiary, limiting errors and fraud.

Add a human check

Multi-factor authentication confirms that the person interacting with the account is its legitimate owner by using one-time passcodes or knowledge-based authentication, providing an additional layer of assurance.

Go beyond pass/fail

Intelligent fraud signals, including behavioural insights, help identify account takeover, mule accounts and other emerging fraud risks.

Flexible decisioning

Configure risk thresholds and receive clear, fact-based response codes – Decline, Risk Alert, Accept with Risk, and Pass – to automate payment and onboarding decisions while reducing manual reviews.

All supported by one connected platform

Reduce integration complexity by bringing together account verification, fraud intelligence, identity verification and monitoring through a single platform. Deploy through a real-time API, batch processing or a secure portal, allowing verification to be incorporated into ERP platforms, payment systems and existing onboarding and fraud prevention workflows.

Verify trust across the payments lifecycle

Identity Verification establishes trust at onboarding by confirming that a customer or business is genuine. Drawing on hundreds of authoritative sources, it verifies identities in real time. Combined with US Bank Account Verification, Identity Verification supports stronger protection across the payments lifecycle.

CUSTOMER STORIES

How have we helped clients reduce fraud?

US Account Verification Solutions support a wide range of organisations that need to verify account details before onboarding, account changes or payments. See how payment processors, banks, lenders, insurers and SaaS platforms use LSEG Risk Intelligence to help reduce fraud, improve operational efficiency and make better-informed payment decisions.

  • A fintech and payment processor was facing high review volumes whenever bank account details were added or changed. The issue was not simply whether the account was valid. The missing signal was ownership: could the organisation confirm who controlled the account before funds were disbursed?

  • A large US card-issuing bank needed to act quickly on suspicious activity without unnecessarily revoking legitimate customer accounts. After an acquisition, it also sought to consolidate fraud investigation tooling across the combined organisation. The key question was simple: could investigators verify account ownership quickly enough to make better decisions before taking action?

  • A leading commercial lender was relying on individual reviewers to spot inconsistencies in voided checks, Federal Employer Identification Number (FEIN) documentation, email addresses and wiring instructions. As fraudulent submissions became more sophisticated, the risk was not confined to one team or one workflow. Could the lender create a consistent electronic verification standard across credit, funding and collections?

  • A digital insurance platform was using more than one provider to verify applicant identities across web, agent and referral channels. One provider appeared to deliver higher match rates, but LSEG was declining identities that the other provider had passed. Which result was right – and what happened when the platform tested those declines against actual fraud outcomes?

  • A SaaS payments provider needed to validate bank accounts across its payment platforms, including for large nonprofit clients with complex banking structures. Document-based checks exposed the business to fraud risk, while credential-based alternatives created delays. Could the provider verify accounts electronically without asking clients to share online banking credentials?

  • A failed verification or risk alert does not always indicate fraud. It means the payment or account update should be reviewed before proceeding.

Configurable response codes in US Account Verification Solutions help organisations automate these decisions while applying the level of review appropriate to the risk.
