The Post Wissel Kantoor notes of the Orange Free State were emergency issues produced as the Second Anglo-Boer War disrupted normal banking entirely. By early 1900, British forces were advancing rapidly and the Republic's financial infrastructure was collapsing — these postal exchange notes were a stopgap measure, never intended as a permanent circulating currency.

The adhesive revenue stamp used as the sole security feature reflects how improvised the whole series was. The Free State was overrun by Roberts' forces in March 1900, and the Republic was formally annexed in May. Most surviving examples from this series emerged from British military seizures rather than normal redemption.
