Definition & Coverage

Payment data validation also includes another important step in bank validation, the IBAN number to BIC Code conversion ( BIC Codes are managed by SWIFT network ). In short it is the ability to determine the correct BIC code from a given IBAN number.

What is the definition of IBAN? The IBAN consists of up to 32 alphanumeric characters, comprising a country code, two check digits and a long and detailed bank account number used in bank wire transfers. The IBAN structure is defined by the international standard under ISO 13616-1:2007 and check digits are performed using MOD 97 (ISO 7064). The individual countries and formatting are described in the official ISO IBAN registry Examples.

The IBAN checker engine supports 97 total countries and all 37 SEPA countries. Our system can respectively identify 97 distinct data structures and perform IBAN format, check digit and length validations.

Increasing the success rate of payments is critical to provide higher quality financial services. Automating payment validations can greatly reduce the loss in bank fees for failed/bounced payments. Both enterprises and small businesses can benefit by our service with our cost-effective pricing plans.

The downside of international transfers with your bank When you send or receive an international transfer with your bank, you might lose money on a bad exchange rate and pay hidden fees as a result. We recommend you use Wise (formerly TransferWise), which is usually much cheaper. With their smart technology: ● You get a great exchange rate and a low, upfront fee every time. ● You move your money as fast as the banks, and often faster – some currencies go through in minutes. ● Wise is a safe and secure service, using encryption and other security measures to protect customer's money. ● Join over 15.6 million customers who transfer in 40+ currencies across 150+ countries.
