  • The first two digits tell you the bank – Kiwibank is 38
  • The next four digits tell you the branch – for Kiwibank this ranges anywhere between 9000-9499
  • The next seven digits tell you the account number
  • The last two digits tell you the account suffix – this will be different for each account.
