ISO 9362 is an international standard for Business Identifier Codes (BIC), a unique identifier for business institutions,[1] approved by the International Organization for Standardization (ISO).[2] BIC is also known as SWIFT-BIC, SWIFT ID, or SWIFT code, after the Society for Worldwide Interbank Financial Telecommunication (SWIFT), which is designated by ISO as the BIC registration authority.[3] BIC was defined originally as Bank Identifier Code[4] and is most often assigned to financial organizations; when it is assigned to non-financial organization, the code may also be known as Business Entity Identifier (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.
The overlapping issue between ISO 9362 and ISO 13616 is discussed in the article International Bank Account Number (also called IBAN). The SWIFT network does not require a specific format for the transaction so the identification of accounts and transaction types is left to agreements of the transaction partners. In the process of the Single Euro Payments Area the European central banks have agreed on a common format based on IBAN and BIC including an XML-based transmission format for standardized transactions. TARGET2 is a joint gross clearing system in the European Union that does not require the SWIFT network for transmission (see EBICS). The TARGET directory lists all the BICs of the banks that are attached to the TARGET2-network being a subset of the SWIFT-directory of BICs.[5]
