A SWIFT code, also known as a BIC (Bank Identifier Code), is a unique identifier used to facilitate international money transfers between banks. It consists of 8 to 11 characters, which include letters and numbers that represent the bank, country, and branch location. This code ensures that funds are sent to the correct financial institution across borders. When sending money internationally, providing the correct SWIFT code is essential for a smooth transaction. Each bank has its own specific code, making it easier for banks to communicate and process payments securely and efficiently.
