In the process of making refunds to customers, obtaining their Bank Identifier Code (BIC) and International Bank Account Number (IBAN) is a crucial step.
For international transactions, BIC and IBAN numbers are the only way to transfer money as this secures the refund to reach the customer's account promptly.
Please get in touch with your Bank to get these numbers for your account.
BID is the international code to identify your bank.
IBAN is the international code for your bank account number.
