Bank Account Checks: Reducing Payment Risk

What is Bank Account Verification?

Bank account verification is the process of ensuring that a bank account's details are accurate, valid, and in certain cases, verifying ownership as well. This process assesses the account number, branch/sort code, IBAN (International Bank Account Number), or routing code to confirm whether the account is active and accessible by the claimed individual or business. Results of this process usually yield outcomes such as "valid/invalid," "status: active/inactive," or even ownership matches, depending on the verification method used.

For instance, consider a business onboarding a vendor for its services. Before initiating a payment, the business utilises a bank account verification system to confirm if the IBAN provided by the vendor matches the account owner’s registered name. This ensures no fraudulent entity receives undue payment.

Importance of Bank Account Verification

Bank account verification is crucial across various scenarios, including routine payments, customer onboarding, regulatory compliance, and fraud prevention. Here are its key advantages:

1. Preventing Fraud and Errors:

  • a. Reduces risks such as direct payment fraud or account takeovers.
  • b. Ensures accurate transactions, reducing chances of misdirected funds.

Example: In invoice fraud schemes, fake beneficiaries often try substituting account details. Verification tools like LSEG Risk Intelligence’s Global Account Verification solution helps prevent such anomalies by cross-referencing account ownership.

2. Supporting Compliance (KYC and Anti-Fraud Standards):

  • a. Regulatory frameworks, such as PSD2 (Payment Services Directive 2) in the EU, emphasise account name verification for SEPA transfers.
  • b. Verification ensures adherence to standards across regions.

3. Operational Efficiency Gains:

  • Accurate accounts reduce chargebacks, bounced transactions, or costly manual investigations.

For these reasons, LSEG Risk Intelligence solutions stand out in stopping ACH fraud and Authorised Push Payment (APP) fraud by verifying accounts across multiple countries efficiently.

What Gets Verified (and What Doesn’t)?

Core Verification Elements:

  • Validity Checks:
    • Account numbers, branch codes, IBAN formats.
    • Status verification (active/inactive/closed).

Ownership Validation:

  • Advanced systems, such as LSEG Risk Intelligence’s powerful verification APIs, can provide an account owner match for both businesses and individuals. Cross-verifying with authoritative datasets ensures full reliability.

Limitations:

While account verification ensures ownership and validity, it doesn't automatically confirm the legitimacy of any transaction done through the account. Fraud-prevention still mandates additional measures like identity checks and transaction monitoring.

Common Methods for Bank Account Verification

1. Micro-Deposits:

In this approach, small test amounts are sent electronically to the provided bank account, and users confirm the credited amounts for validation. While effective, this method takes time due to bank processing delays.

2. Instant or API-Based Verification:

Through API integrations, such as LSEG Risk Intelligence’s global solutions, organisations can carry out real-time checks by connecting directly to global banking networks or databases.

3. Document-Based Processes:

Users might need to upload account statements or official letters for manual assessments. This is still common in corporate cases but is slower than automated digital checks.

Duration of Bank Account Verification

The time taken depends largely on the verification method:

  • API Tools & Instant Verification: Near real-time validation is achievable with APIs.
  • Micro-Deposits: May take 24–72 hours due to banking workflows.
  • Document Processing: Requires manual reviews, which can lead to delays based on workload.

When using automated solutions within LSEG Risk Intelligence’s Account Verification suite, verifications are efficiently executed through pre-integrated real-time processes supported by seamless API connectivity.

Bank Account Verification Letter: Essential Details

Businesses and financial setups often request verification letters to confirm:

  • Account details and ownership.
  • Status of the account (active/closed).

Application in Industries:

  • Corporate Onboarding: Ensures vendor accounts are properly listed.
  • Payroll Management: Checks account activity for correct payouts.
  • Cross-Border Vendors: Used when other verification channels aren't reliable.

Fraud Prevention and Bank Account Verification

Key Fraud Scenarios:

  • Invoice Redirection: A fraudster changes the beneficiary details to divert payments.
  • Unauthorized ACH Payments: Verifying routing information or payer/payee integrity mitigates US-specific ACH fraud risks.
  • Account Takeovers: Identifying suspicious changes in ownership patterns.

By triangulating LSEG’s Risk Intelligence data with fraud detection alerts, organisations reduce the exposure to these risks substantially.

Handling Failures in Bank Account Checks

Failures result from:

  • Inaccurate data input (wrong account numbers or mismatched names).
  • Unsupported banks or countries.
  • Process errors like delays in document review pipelines.

In such cases:

  1. Use step-up verification methods, such as document proofing.
  2. Deploy change-control mechanisms (multiple approvals for updates).
  3. Maintain detailed audit trails for all exceptional remediations.

LSEG Risk Intelligence solutions, such as the World-Check One, can support accurate remediation workflows by providing tools to assist with detailed checks and audit trails
