Serial Numbers

Not all denominations of Australian banknotes are produced every year. Instead, they are printed based on demand for new banknotes to replace those no longer fit for circulation. The information below details the serial number ranges for those banknotes printed each year. This information does not account for the serial numbers used on banknotes that are destroyed and therefore not issued.

Before viewing this information, please read the disclaimer below.

Some of the banknote prefix and serial number information has been compiled from incomplete records, and it is possible that banknotes have been issued with serial numbers outside of those published in the above tables.
