Stop payment failures before they cost you.

Bank account verification is the process of confirming that a beneficiary's bank account details are valid before a payment is sent. A bank account verification API can verify account existence, validate account ownership, and confirm that account details match the intended recipient, helping businesses reduce failed payments and fraud.

Nium's account verification API performs real-time account verification by validating beneficiary bank account details against connected clearing systems and financial institutions. Businesses submit the account holder name, account number, and bank identifier, and receive an instant response indicating whether the account is verified.

Nium supports global bank account verification across a growing network of markets, including key payout corridors across APAC, Europe, and other major payment destinations. Coverage continues to expand through Nium's direct clearing system and banking integrations.

Nium verifies both individual and corporate bank accounts. Verification is based on the location of the beneficiary account, not the payment method used to fund it. This means Nium can verify accounts regardless of whether payments are ultimately delivered via local payment rails or wire transfers, helping businesses validate beneficiary details across a wider range of payout and collection workflows.

Yes. Industry data shows that 60–70% of failed payments are caused by incorrect beneficiary account details. By performing a pre-payment account check before funds are released, businesses can significantly reduce failed payments, returned transactions, and operational costs.

Yes. Nium supports bank account validation and IBAN verification in supported markets, helping businesses verify beneficiary account details before initiating domestic or cross-border payments.

The Nium Verify bank verification API response returns three core data points: account status (valid or invalid), account holder name retrieved directly from the recipient's bank, and a name match score indicating how closely it aligns with the name you submitted.

This gives you a complete pre-payment signal in a single API call — not just a yes or no, but the context to act on it. A confirmed name match clears the payment. A low name match score flags the record for review. An invalid account status stops the payment before funds move. The response is returned within seconds, with no test transaction required. Nium Verify also surfaces this data through the Nium Portal for teams operating without direct API integration, supporting Confirmation of Payee compliance requirements in the EU and UK.

Using Nium Verify before sending payments achieves a 99% payout success rate, compared to the 10–15% failure rate that occurs without beneficiary account verification.
