It usually refers to the bank code, country code, location code, and branch code. It is also used to identify financial institutes globally.

IBAN is an international numbering system that is used to identify an overseas bank account. It usually consists of country code followed by some number and then alphanumeric characters.

It is a method to verify that transaction details are correct or not. It also helps to identify individual account which is involved in an international transaction.

What is Swift Code?

The Swift stands for Society for Worldwide Interbank Financial Telecommunication. It acts as an intermediary during the process of international transactions. It was founded in Brussels in 1973.

It is a standardized way that is accepted globally. It also supports a secure messaging network.

Swift provides a mechanism to secure the communication between two banks. It takes the message from the first bank, performs certain actions for reliable delivery, and then sends it to the destination bank.

Swift usually works under four different fields, which are security, treasury, trade services, and cash management.

When we conduct any international money transfer, then a swift code is used to identify the bank account. It consists of a set of 8 or 11 digits which is used to identify our branch.

This system assigns a unique number to each financial institution, and that unique number is either 8 or 11 digits long. With this unique number, our bank is identified during the transaction.

This system is beneficial because it allows the banks to send additional data like the status of the account, debit amount, credit amount, etc.

The first four characters are bank codes, the next two characters represent country code, the next is a combination of letters or digit to represent the location, and the last three characters or digits represent branch code and are optional.

What is IBAN Number?

The International Bank Account Number, which is also called IBAN, is a system that is recognized internationally and used to identify bank accounts so that communication takes place more safely without any error.

It consists of 34 alphanumeric characters, i.e., a country code, then two digits for redundancy check, then domestic bank account number, branch identifier, and then routing information.

Here country code consists of 2 letters, check digits have 2 digits, Basic Bank Account Number has up to 30 alphanumeric characters. Check digits are used as redundancy digits so that no error can occur.

IBAN’s main aim is to bring validation while the process of data entry takes place. The algorithms used in this process need to be very perfect because the transaction is a crucial process.

IBAN process consists of three basic algorithms, i.e., validating IBAN, generating checksum, and modulo operation.

This is a standard method that is adopted by all international transactions. It provides the most essential feature of security. IBAN helps to identify branches also. That’s why it is used in almost all European countries.

It helps to eliminate errors in the transaction process. It helps large businessmen to take whatsoever amount in whatever currencies.
