What do all the numbers on my ASB Bank account mean, what are they used for?

Last Updated: 14 Mar 2014

Each of the numbers on your ASB account has a very good reason for being there. Let’s break it down and explain by segments.


BB: This is the bank you hold the account with eg 12 means your account is with ASB.

OOOO: This number represents the branch where your account is held.

XXXXXXX: This is your unique account number.

SS:  This is your account suffix. Different products have different suffixes to keep them separate from each other.  For example the suffix code range for savings accounts is 50 to 60.
