What is an IBAN Number?
IBAN (stands for International Bank Account Number) is an internationally recognized code, BAN consists of a series of numbers and letters, the format and length vary from country to country, but usually includes country code, check code, bank code and account number and other parts, up to 34 letters and numbers. The use of IBAN greatly reduces the chance of errors in international monetary payments and transactions, while speeding up execution. If the wrong IBAN is entered, it can result in the money being returned or transferred to the wrong account, so it is vital to ensure that the IBAN is accurate when making international transfers.
IBAN consists of the following parts
Country code: consists of two letters, representing the country where the account is located
Check bit: two digits to check whether the IBAN is correct and help detect errors.
Bank identifier: Used to indicate the bank where the account is located.
Basic Bank Account Number (BBAN) : Up to 30 characters, containing country-specific bank account information such as bank code and branch code.
Development history:
The need for complexity in global financial transactions grew during the 1990s. The idea of IBAN was first put up by the European Committee on Banking Standards (ECBS) in 1997 with the intention of establishing a consistent standard for international payments. In 2007, the International Organization for Standardization (ISO) accepted IBAN as ISO 13616, a standard that outlines its format and structure. It became a worldwide recognized system.

Differences between IBAN Number and SWIFT Code
As an important identification tool in international financial transactions, the two have different functions and structures, the main differences are as follows:
-
Different scope of use
The IBAN number (International Bank Account number) is widely used in many countries and regions. IBAN has been accepted by nearly all European nations, particularly the European Economic Area (EEA), or the one-Euro Payments Area (SEPA). These two are part of the European Union. Many nations in the Middle East and North Africa, including Saudi Arabia, Qatar, the United Arab Emirates, and others, have also embraced IBAN. Despite its widespread use, not all nations make use of IBAN. For instance, SWIFT codes are commonly used by banks in China and the United States for international transactions.
-
Different use functions
IBAN recognizes not only a bank but also an account, whereas SWIFT codes only recognize the bank itself.
Special note: When sending money to most European countries, you need to have both the SWIFT Code and IBAN Number, and your money will enter Europe through the SWIFT Global system, and then be divided by the IBAN to the specific bank.
The role of IBAN Number in international trade
- Increase efficiency
IBAN provides a standardized international identification system for bank accounts It can make the processing of cross-border payments more automated and efficient. In international trade, businesses or individuals can quickly and accurately send funds to a bank account abroad by providing an IBAN number.
- Reduce errors
IBAN contains check bits that detect and prevent errors during input, such as reversals of numbers or letters, omissions, and so on. This helps to reduce the risk of trading failures due to incorrect account information or funds straying into other accounts.
- Increase transaction security:
IBAN's standardized format makes account information for every international transaction more clearly available, helping banks and companies track the flow of money. In international trade, this provides strong support for the prevention of fraud and illicit financial flows.
