What is bank account validation?

Bank account validation is the process of verifying the accuracy and legitimacy of a bank account number & sort code provided by the customer. This is done by cross-referencing the international bank account number (IBAN) against valid accounts held by banks and financial institutions participating in the Extended Industry Sort Code Database (EISCD).

IBAN number: This consists of up to 34 letters and numbers in the following structure: country code, check digits, bank code, sort code, and UK account number. For example, GB 12 ABCD 102030 12345678.

EISCD: This contains payment-related information for every financial institution participating in the UK’s Bacs, CHAPS, Cheque and Credit Clearing, and Faster Payments schemes.

Why is it important to validate bank account details?

Validating bank account details is essential in protecting any person from fraudulent payments. This occurs when a criminal uses stolen payment information, falsifies payment details, or impersonates a legitimate payee. By validating bank details, you ensure any payment received is from a legitimate customer.
In the UK, all businesses are required by law to comply with anti-money laundering regulatory requirements. You must verify the identity and legitimacy of every customer; failure to do so will result in severe fines, legal action and criminal charges.

Alongside protecting the general public, it also protects you and your business. By accurately & efficiently confirming information, you avoid payment errors and delays caused by incorrect data. This will improve your reputation and create an improved customer experience, making the customer feel safe when purchasing your products or services.


Why use Hopewiser?

If you accept online bank payments, you need a reliable system to check and validate customer information.

Using the EISCD, our service refines your payment process by using real-time bank verification. This saves time & money and ensures quick & accurate verification of customer details within your eCommerce shopping cart or internal systems used for offline payment processing.

Depending on what works for your business, decide between the web app or Soap API and start benefiting from bank validation from just 3.7p per lookup.
