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.
