Banking; Banking telecommunication messages; Bank identifier codes

This technical specification establishes a standardized framework for the unique identification of financial institutions engaged in interbank transactions. Designed to facilitate secure and efficient electronic communication across global banking networks, it defines the structure and assignment rules for a specific four-character alphabetic code, commonly known as a bank identifier. The document outlines the logical hierarchy of the identifier, ensuring that each participating entity within the international financial community is assigned a distinct and unambiguous code. This system supports the accurate routing of telegraphic messages, including instructions for fund transfers and other critical banking operations, thereby minimizing errors and enhancing the reliability of cross-border financial data exchange. By providing a consistent method for designating financial entities, the standard serves as a foundational element in the architecture of international money transmission systems, enabling seamless interoperability between diverse banking systems and communication protocols without the need for additional manual verification.
