What is the purpose of a postcode? Can postcodes be changed?
Australia Post introduced the postcode system to facilitate the processing and delivery of mail. Postcodes are designed for delivery purposes and indicate the delivery office or centre from which mail deliveries are made. From time-to-time Australia Post makes changes on the basis of providing either customers with an improved standard of service or Australia Post with some operational improvements. Australia Post is aware that many other organisations make use of, or refer to postcodes for non-mailing related purposes. The Corporation cannot restrict organisations in such use of postcodes; however, postcodes are maintained by Australia Post for the efficient processing of mail.
