A SWIFT code, also known as a BIC (Bank Identifier Code), is a standard format for uniquely identifying banks globally, especially during international transactions. It comprises 8-11 characters. The first 4 characters represent the bank's code, the next 2 denote the country, followed by 2 for the city. The remaining characters (which are optional) specify the bank's branch. This system ensures secure and efficient cross-border transfers. For instance, when sending money overseas, one would need the recipient's bank SWIFT code. It acts as an address that tells where to send the money, ensuring funds reach the correct institution.
