By using POSTman, you can easily add these barcodes to your mail. POSTman validates your addresses against Australia Post’s Postal Address File and appends the barcodes. This can be done from many commonly used applications such as Microsoft Word, Excel and 32-bit Access.
By adding barcodes, you can save on your postage, and as POSTman validates each address to barcode it, you can be assured that your mail will be delivered. This means you also reduce the quantity of costly returned mail.
