Postcodes in Australia
Postcodes in Australia are used to more efficiently sort and route mail in the Australian postal system. Postcodes in Australia have four digits and are placed at the end of the Australian address, before the country. Postcodes were introduced in Australia in 1967 by the Postmaster-General's Department and are now managed by Australia Post, Australia's national postal service. Postcodes are published in booklets available from post offices or online from the Australia Post website.
Australian envelopes and postcards often have four boxes printed in orange at the bottom right for the postcode. These are used to assist with the automated sorting of mail that has been addressed by hand for Australian delivery.
Postcodes were introduced in Australia in 1967 by the Postmaster-General's Department (PMG) to replace earlier postal sorting systems, such as Melbourne's letter and number codes (e.g., N3, E5) and a similar system then used in rural and regional New South Wales. The introduction of the postcodes coincided with the introduction of a large-scale mechanical mail sorting system in Australia, starting with the Redfern Mail Exchange in Sydney.
The initial digit of each postcode was copied directly from the previously-existing numerical prefixes of Australian radio call signs, which were based on state/territory borders. Over time, however, the initial digits of postcodes have deviated from the radio system, for example, the 8000 series refers to special addresses in Victoria. It is sometimes stated, incorrectly, that the initial digits of the postcodes corresponded to the geographical boundaries of the official Australian Military Districts, that existed in 1911–1997. In fact, only the boundaries of the initial 2- and initial 3– postcodes were ever similar to the former 2nd and former 3rd Military Districts, respectively.
By 1968, 75% of mail was using postcodes, and in the same year post office preferred-size envelopes were introduced, which came to be referred to as "standard envelopes".
Postcode squares were introduced in June 1990 to enable Australia Post to use optical character recognition (OCR) software in its mail sorting machines to automatically and more quickly sort mail by postcodes.
Australian postcodes consist of four digits, and are written after the name of the city, suburb, or town, and the state or territory:
