In international banking transactions, IBAN (International Bank Account Number) is a standardized number used to identify bank accounts, mainly used in European and Middle Eastern countries. Many users are confused about the differences between IBAN and ordinary bank account numbers, especially when making cross-border remittances, and are unsure which number to use. This article will provide a detailed answer to the differences between IBAN and account numbers, inquiry methods, formats, uses, and their impact on international payments, helping users better understand and use IBAN for financial transactions.

Although both IBAN and ordinary bank account numbers are used to identify bank accounts, there are significant differences in their functions and formats.
For example, a German IBAN might be DE89 3704 0044 0532 0130 00, where DE is the country code, 89 is the check digit, and the remaining part is the bank and account information. An ordinary bank account number may only have 8-12 digits and cannot be directly used for international remittances.
Both IBAN and BIC (Bank Identifier Code) are used in banking transactions, but they have different functions:
For example, the BIC of a certain bank might be DEUTDEFFXXX, while the IBAN of its customers is a complete account identification number. In many international transfer scenarios, both IBAN and BIC need to be provided to ensure the smooth transfer of funds.
The format of IBAN varies by country, but it usually includes the following parts:
For example, a UK IBAN might be: GB29 NWBK 6016 1331 9268 19
Before making a remittance, be sure to check whether the IBAN is correct to avoid remittance failure or loss of funds.
The main methods for inquiring about an IBAN number include the following:
Since IBAN is the key identification information of an account, it is recommended that users keep it carefully and do not disclose it casually to prevent potential financial fraud.
The use of IBAN numbers helps to improve the efficiency and security of international remittances. The specific advantages include:
Since IBAN is a standardized global account format, many international remittance platforms require users to enter an IBAN to complete a payment.
Although the structure of IBAN is standardized, the IBAN formats of different countries are different. For example:
When making international remittances, be sure to fill in the IBAN format accurately to avoid transaction delays or failures due to format errors.
Generally speaking, an IBAN account can receive remittances in multiple currencies, and there is no need to apply for multiple IBANs for different currencies. The bank will automatically convert the remittance currency into the account currency or allow the user to choose the conversion method.
For example, the IBAN of a UK bank account can receive US dollars, euros, or British pounds at the same time, and the bank will convert them into the account’s default currency according to the current exchange rate. This flexibility greatly improves the practicality of IBAN accounts, making them a standard tool for international payments.
As a globally standardized bank account identification number, IBAN plays a crucial role in international remittances. Its design improves the efficiency of cross-border payments, reduces transaction errors, and provides a more secure way to transfer funds.
However, for some cross-border remittance needs that require a higher amount and a faster arrival speed, IBAN may not be the most ideal choice.
