BBAN (Basic Bank Account Number)

A Basic Bank Account Number (BBAN) is the country-specific portion of an IBAN that identifies the bank and account within a particular nation's banking system. BBAN formats vary by country and include the domestic bank code, branch code, and account number. Understanding BBAN structure helps investigators parse account identifiers and check that an identifier is well-formed when only domestic account details are available.
