Person (address)—postal delivery point identifier, {N(8)}

In October 1999, Australia Post introduced a bar-coding system for bulk mail lodgements. Agencies or establishments can use software to improve the quality of person address data it collects and records and, at the same time, receive financial benefits by reducing its postage expenses.

The DPID is easily converted to a bar code and can be included on correspondence and address labels. If the bar code is displayed on a standard envelope that passes through a mail-franking machine (e.g. as used by most major hospitals), the postage cost is reduced. Every three months, Australia Post provides updates to the PAF database. For more information, contact Australia Post.
