In New Zealand, bank numbers follow a 16 digit format.
This consists of:
- The prefix (two digits)
- The branch number (four digits)
- The account number (seven digits)
- The suffix (two digits)
Whenever you receive somebody's bank account number (for example, from a Trademe seller or to pay a friend), you can tell which bank they are with by the prefix.
Every bank in New Zealand has a unique prefix, which is used as the first two digits of every NZ bank account number.
For example, if the bank number is 12-3073-0100291-01 then you know they are with ASB due to the prefix 12.
