Account number is a unique string of digits assigned by a bank to identify an individual account holder's account. IBAN (International Bank Account Number), on the other hand, is a standardized international numeric system that includes the country code, bank code, and individual account number, allowing for streamlined cross-border transactions. While the account number is primarily used for domestic transactions, the IBAN ensures accuracy and efficiency in international banking.
