In today’s global economy, cross-border payments have become common practice for individuals and businesses. Millions of money transfer transactions between millions of countries take place every day. The realization of sending money transactions and the accuracy of the international bank account number (IBAN) is very important to prevent many disruptions. In today’s technologies, many money transfer applications use IBAN checker API for this. This is also known as the IBAN lookup API.

The use of an IBAN checker API has eliminated costly errors and delays for many businesses. For this reason, it has a critical role in businesses. In this article, we will look closer at the importance of an IBAN checker API in payment transactions. But first, let’s look at what an IBAN is and how it is structured.


What is an IBAN (International Bank Account Number)?

IBAN (International Bank Account Number) is an account number used in international money transfers. The IBAN is used to identify the recipient’s bank account. It includes the recipient’s bank, bank code, account number, and other information. IBAN helps send money faster and more securely because the recipient’s bank account is defined according to international standards.

Most European banks require an IBAN today to send or receive money. IBAN is also a verification method to prevent the use of incorrect account numbers or bank information.

In general, the format of the IBAN may vary from country to country, but creating it according to the ISO 13616 standard is necessary.

For example, IBAN numbers in Turkey are 26 characters long and have the following format:

IBAN example: TRkk bbbb bccc cccc cccc cccc cc

Here, “TR” represents the country code, “k” the check digit, “b” the bank code, and “c” the last characters of the account number.


What is the Importance of IBAN Lookup in Payment Transactions?

Using an IBAN lookup is crucial for applications that involve sending money. It verifies that users have accurately entered the IBANs to which they intend to transfer funds. The long and intricate format of IBAN varies from country to country. It can easily lead to mistakes when entering it. Transferring money to the wrong account or bank may result in a loss of money or delays due to an incorrect IBAN.

The IBAN checker verifies that the IBAN is in the proper format, that the country code is correct, and that the check digit is calculated correctly. This prevents the use of incorrect IBANs and guarantees that money transfers reach the appropriate accounts and banks. Moreover, the IBAN checker provides a faster, more dependable method of transferring funds by preventing human errors.

Online banking applications are among the most popular applications using the IBAN checker.
