You'll need to buy Address Matching Approval System (AMAS) certified software to generate a unique 8-digit number, known as the Delivery Point Identifier (DPID) for each address. The DPID is then turned into a barcode.
Mail houses specialise in preparing and sorting your mail, and can help manage a single part of your mail, such as barcoding - or your entire mailing from creation to lodgement. If you need a mail house, you can find one in our list of Bulk Mail Partners.
Help with barcoding
The Barcode Quality Program can help with all your barcoding software and printer certifications, and will help you ensure the right kind of barcodes (known as 4-state barcodes) are generated and printed within the Australia Post barcoding specifications.
You'll also find helpful information in our Barcoding tools and guides.
