which part of an iban is the account number
International Bank Account Number The Basic Bank Account Number (BBAN) format is decided by the national central bank or designated payment authority of each country. There is no consistency between the formats adopted. The national authority may register its BBAN format with SWIFT, but is not obliged to do so. It may adopt IBAN without registration. SWIFT also acts as the registration authority for the SWIFT system, which is used by most countries that have not adopted IBAN. A major difference between the two systems is that under SWIFT there is no requirement that BBANs used within a country be of a pre-defined length.
Bank statement Today, the monthly mailing of bank statements is the norm in many countries. It is not customary in some countries, such as Japan, where individual account holders are expected to keep track of deposits, withdrawals, and balances using their own passbooks at ATMs.
