SWIFT stands for the Society for Worldwide Interbank Financial Telecommunication. SWIFT code is a standard format of Business Identifier Codes approved by the International Organization for Standardization (ISO). It is a unique identification code for both financial and non-financial institutions. When assigned to a non-financial institution, the code may also be known as a Business Entity Identifier or BEI. These codes are used when transferring money between banks, particularly for international wire transfers, and also for the exchange of other messages between banks. The codes can sometimes be found on account statements.
