When would you need to use an IBAN checker?

You would need to use an IBAN checker in several scenarios, mainly related to international transfers to ensure the accuracy and validity of IBANs. Here are some common situations:

What are the benefits of using an IBAN checker?

An IBAN checker can check if an IBAN is correct, by confirming information such as the BIC/SWIFT code, bank name, address, and country. The benefits of using this online tool, ahead of sending a money transfer, include:

  • Accuracy: Ensures that the IBAN is correctly formatted and valid, reducing the risk of transaction errors.

  • Efficiency: Saves time and resources by catching errors early in the process.

  • Compliance: Helps meet regulatory and industry standards for international banking.

  • Validation: the IBAN checker can validate every single element of an IBAN (country regions, the bank code, branch code, and account number)

Briefly about IBANs

An IBAN, or International Bank Account Number, is used to identify the unique account of a customer at a financial institution in any of the 80 countries that use the system.

All IBANs share the same format and are compatible with the internationally agreed-upon system originally adopted by the European Committee of Banking Standards (ECBS) in 1997. Since then, the system has been extended by the SWIFT (Society of Worldwide Interbank Financial Telecommunication) network and now includes additional countries around the world, outside of Europe.

IBANs are made up of 34 - 35 alphanumeric characters, consisting of a two-digit country code, two check numbers, a four-digit bank code, a six-digit bank branch code, and an eight-digit bank account number, like so:

Example IBAN:
GB33BUKB20201555555555
Country Code:
GB
Check Number:
33
Bank Identifier:
BUKB
Sort Code:
202015
Account Number:
55555555
