How can I verify an international bank account number?

To verify an International Bank Account Number (IBAN), you can follow these steps: first, check the IBAN's format, ensuring it has the correct number of characters for the specific country; each country has its own IBAN structure. Next, perform a checksum validation using the algorithm specified by the IBAN standard, which typically involves rearranging the IBAN and performing a modulus operation. Additionally, you can use online IBAN validation tools or contact the bank associated with the account for confirmation.
