). The south-western Victoria
3221 postcode of the Geelong
Mail Centre also includes twenty places around Geelong with very few people. This means that mail for these places is not fully sorted until it gets to Geelong. Some postcodes cover large populations (e.g., postcode 4350 serving some 100,000 people in Toowoomba
), while other postcodes have much smaller populations, even in urban areas. Australian postcodes range from 0200 (for the Australian National University
) to 9944 (Cannonvale, Queensland).
Some towns and suburbs have two postcodes—one for street deliveries and one for post office box
es. For instance, a street address in the Sydney suburb of Parramatta
would be written like this:
But mail sent to a PO Box in Parramatta would be addressed:
Many big businesses, government departments and other institutions receive large volumes of mail. They can have their own postcode as a Large Volume Receiver (LVR), e.g. the Royal Brisbane and Women's Hospital
has the postcode 4029. More postcode ranges were made available for LVRs in the 1990s.
Sometimes near the state and territory borders, Australia Post finds it easier to send mail through a nearby post office that is across the border:
These postcodes do not follow the above rule:
Some or all of the postcodes above may cover two states. For example postcode 2620 covers both a suburb in NSW (Gundaroo) as well as a suburb in the ACT (Hume) - the postcode is within the ACT range.
Jervis Bay Territory
, once an exclave of the ACT but now a separate territory, is geographically located on the coast of NSW. It is just south of the towns of Vincentia and Huskisson, with which it shares a postcode. Mail to the Jervis Bay Territory is still addressed to the ACT.
The numbers used to show the state on each radio callsign in Australia is the same number as the first number for postcodes in that state, e.g. 2xx in New South Wales, 3xx in Victoria, etc. Radio callsigns pre-date postcodes in Australia by more than forty years.

boxes in any capital city (though Perth now uses a different range of postcodes for its GPO Boxes):
Postcodes with a second number of "0" or "1" are almost always located within the metropolitan area of the state's capital city. Postcodes with higher second numbers are usually located in rural and regional areas. Common exceptions are where towns were rural when postcodes were first introduced in 1967, but have since been suburbanised and incorporated into metropolitan areas, e.g. Penrith, New South Wales
has the postcode 2750 and Petrie, Queensland
has the postcode 4502.
Within each region with the same second number, postcodes usually get bigger the further one travels from the state's capital city along major highways and railways. For instance, heading north on the North Coast railway
in New South Wales away from Sydney:
has the postcode 4700 and Ballarat, Victoria
has the postcode 3350. There are exceptions; the major town of Ipswich, Queensland
has the postcode 4305, while Goodna
, a relatively unimportant suburb of Ipswich, is allocated 4300.

Australia Post says that postcode squares should not be used for machine-addressed mail, or mail going overseas.
companies often use postcodes when working out the cost of car and house insurance. The NSW Ministry of Transport uses postcodes to give specific numbers for each bus stop in Greater Sydney. The stop number is five to seven numbers: the first four are the postcode, and the others show the bus stop (sometimes written with a space in between, e.g. "2000 108"). Many companies that produce metropolitan street maps also list the postcodes for each suburb, both in indexes on the maps themselves.
. This number might be 12 numbers long. This system enables the post office to place items in delivery order.
Companies can also use Rapid Addressing Tool(RATS) to print what is call Customer Addressed Barcodes that are printed above the address.
Every Delivery Point in Australia (DPID) has its own number.
The machines that sort mail are Barcode Sorter(BCS)sorts and sequences letters up to C5 size. MARS sequences letters up to C5 articles. Flat multi level ocr (FMOCR) Reads inprints and sorts C5 to A3 size articles.

Allocation within states
While the first number of a postcode usually shows the state or territory, the second number usually shows a region within the state. However, postcodes with the same second number are not always next to each other. As an example, postcodes in the range 2200—0001 are split between the southern suburbs of Sydney and the Central Coast of New South Wales.Postcodes with a second number of "0" or "1" are almost always located within the metropolitan area of the state's capital city. Postcodes with higher second numbers are usually located in rural and regional areas. Common exceptions are where towns were rural when postcodes were first introduced in 1967, but have since been suburbanised and incorporated into metropolitan areas, e.g. Penrith, New South Wales
Penrith, New South Wales

Many companies that produce metropolitan street maps also list the postcodes for each suburb, both in indexes on the maps themselves.

To improve mechanised sorting, each address now has a sorting number which is printed on the letter as an orange coloured barcodeBarcode

Originally barcodes represented data by varying the widths and spacings of parallel lines, and may be referred to as linear or 1 dimensional . Later they evolved into rectangles,...
