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 specific branch. 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 to avoid delays or misdirected payments. Each bank has its own SWIFT code, making it easier for financial institutions to communicate and process transactions securely and efficiently.
