Postcodes in Australia

Australia postcodes were introduced and implemented in 1967 in an effort to make mail routing much easier across the country. Postmaster-General’s Department (predecessor of Australia Post) spearheaded the initial implementation of postcodes in the country.

 

The codes replaced older postal sorting systems, including the alphanumeric codes used in Melbourne and a similar coding system used across regional and rural areas in New South Wales. Postcodes in Australia are allocated using a basic theory making them quite straight forward.

Basically, the postcodes have four digits, which should follow the address of the recipient. Specific Australian states are allocated specific postcodes.

 

 

All addresses in the Australian Capital Territory follow postcodes starting in 26—and 29--. Those in NSW start with 2, Northern Territory 08, Queensland 4, South Australia 5, Tasmania 7, Victoria 3 and Western Australia 6.

There are various number ranges assigned to PO Boxes. There are also several exceptions to the rules, particularly addresses in state borders that are logically geographically confusing.

Some postcodes may span beyond a state. In addition, there are also particular postcodes for the country’s external territories and islands.

Postcodes assigned to territory and state capital cities are different, so they could be easily remembered and identified.

 

As a general rule, all Australia postcodes assigned to such cities are ending with two to three zeroes. General PO Box codes often end in 01. For example, postcode in Sydney, NSW is 2000 while PO Box address code is 2001. In Canberra, it is 2600, while PO Box is 2601, in Melbourne it is 3000 and 3001, respectively and so on. Capital city postal codes are the lowest codes in the state or territory area.

To make mailing better, more effective, easier and more accurate, there are also Post Office Preferred envelopes that are sold across the country. Such envelopes (first introduced in the 1990s) feature four squares that are located at envelope front’s bottom right corner. Australia Post often refers to such squares as Postcode Squares, containing destination postcode for the mail address. Such squares also make the job easier and more accurate for the automated mail-sorting machines used. Such equipment utilizes a software for optical character recognition.

Aside from the mail sorting functions by the Australia Post, postcodes have also been used by many other organizations and private businesses. In particular, insurance firms are using such codes in calculating house and car insurance premiums. NSW’s Ministry of Transport is also using postcodes in assigning specific numbers for every bus stop across the Greater Sydney area. Such bus stop numbers consist of six digits; postcodes occupy the first four while the two last digits are specifically assigned. Street directories also list postcodes for every suburb in maps and indexes.
