Postcodes are a vital component of Australia's mailing and addressing system, introduced in 1967 to streamline mail sorting and delivery. These four-digit codes are organized by state and territory, with some ranges reserved specifically for Licensed Postcode Virtual Runs (LVRs) and PO Boxes to ensure efficient handling of bulk mail and secure delivery to designated addresses.
