From Wikipedia, the free encyclopedia

Australian postcodes have four digits; envelopes for posting within Australia reflect this.

Postcodes are used in Australia for the purposes of sorting and directing mail. All postcodes in Australia consist of four numbers and are placed at the end of the address. Australian postcodes are allocated and managed by Australia Post.

Postcodes are published in small booklets available from post offices, and also in the white pages of telephone directories.

On envelopes and postcards there are usually four rectangular boxes printed in orange ink at the bottom right for the postal code digits.

History

Postcodes were introduced in Australia in 1967 by the Postmaster-General's Department (PMG), the predecessor of Australia Post. They replaced earlier postal sorting systems, such as Melbourne's alphanumeric codes (e.g., N3, E5) and a similar system once used in rural and regional New South Wales.

For a history of the PMG / Australia Post see here.[1]

Format

Australian Postcodes are four digits long, and written after the name of the city, suburb, or town, and the state or territory:[2]

Mr John Smith
400 Kent Street
SYDNEY NSW 2000

Geography

Australian postcodes are routing information, and while they are often associated with a single bounded geographical area (e.g. suburb or town) they are not always contiguous areas. They sometimes have quite complex geography, especially in areas beyond the urban fringe (e.g. the southern Queensland 4352 postcode). The south-western Victoria 3221 postcode of the Geelong Mail Centre also includes twenty sparsely-populated localities around Geelong signifying that mail for these places is not fully sorted until received at Geelong. Some postcodes cover large populations (e.g., postcode 4350 serving some 100,000 people in the City of Toowoomba), while other postcodes have much smaller populations, even in urban areas. The postcodes range from as low as 0200 (for the Australian National University) to 9729 (mail addressed to the Gold Coast City Council).

Some postcodes are associated with a single town or suburb (e.g. 6160 belongs only to Fremantle, Western Australia), while other postcodes are shared by many localities (e.g. 2570 belongs to twenty-two towns and suburbs around Camden, New South Wales).

Some towns and suburbs have two postcodes—one for street deliveries and one for post office boxes. For instance, a street address in the Sydney suburb of Parramatta would be written thus:

Mr John Smith
99 George Street
PARRAMATTA NSW 2150

But mail sent to a PO Box in Parramatta would be addressed:

Mr John Smith
PO Box 99
PARRAMATTA NSW 2124

Many corporations, government departments and other institutions receive large volumes of mail, and are entitled to 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, though LVRs do not necessarily use postcodes in these new ranges.

States and territories

The first one or two digits generally denotes the state or territory that the postcode belongs to:[3]

State/Territory Abbreviation Postcode range
New South Wales NSW 1000—1999 (LVRs and PO Boxes only)
2000—2599
2619—2898
2921—2999
Australian Capital Territory ACT 0200—0299 (LVRs and PO Boxes only)
2600—2618
2900—2920
Victoria VIC 3000—3999
8000—8999 (LVRs and PO Boxes only)
Queensland QLD 4000—4999
9000—9999 (LVRs and PO Boxes only)
South Australia SA 5000—5799
5800—5999 (LVRs and PO Boxes only)
Western Australia WA 6000—6797
6800—6999 (LVRs and PO Boxes only)
Tasmania TAS 7000—7799
7800—7999 (LVRs and PO Boxes only)
Northern Territory NT 0800—0899
0900—0999 (LVRs and PO Boxes only)

Some exceptions to these postcode ranges occur in the vicinity of state and territory borders, where Australia Post finds it more convenient to direct mail through a nearby post office that is across the border:

0872 ERNABELLA NT SA
0872 FREGON NT SA
0872 INDULKANA NT SA

3585 MURRAY DOWNS VIC NSW
3586 MALLAN VIC NSW
3644 BAROOGA VIC NSW
3644 LALALTY VIC NSW
3707 BRINGENBRONG VIC NSW

Some or all of the postcodes above may span 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, previously an exclave of the ACT but now a separate territory, is geographically located on the coast of NSW, 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 digits used to denote the state on each radio callsign in Australia is the same digit as the first digit 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.

External territories

Australia's external territories are also included in Australia Post's postcode system. While these territories do not belong to any state, they are addressed as such for mail routing purposes:

External territory Postal state Postcode
Norfolk Island NSW 2899
Christmas Island WA 6798
Cocos (Keeling) Islands WA 6799

Three scientific bases in Antarctica operated by the Australian National Antarctic Research Expeditions share a postcode with the isolated sub-Antarctic island of Macquarie Island (part of Tasmania):

Antarctic base Postal state Postcode
Casey Station TAS 7151
Davis Station TAS 7151
Mawson Station TAS 7151

State and territory capital cities

Each state or territory's capital city ends with two zeroes or three zeroes. Capital city postcodes were the lowest postcodes in their state or territory range, before new ranges for LVRs and PO Boxes were made available in more recent times. The last digit can usually be changed from "0" to "1" to obtain the postcode for General Post Office boxes in any capital city (though Perth now uses a different range of postcodes for its GPO Boxes):

City State/Territory Street Address GPO Box Address
Sydney NSW 2000 2001
Canberra ACT 2600 2601
Melbourne Vic 3000 3001
Brisbane Qld 4000 4001
Adelaide SA 5000 5001
Perth WA 6000 6837—6848
Hobart Tas 7000 7001
Darwin NT 0800 0801

Allocation within states

While the first digit of a postcode usually indicates the state or territory, the second digit usually denotes a region within the state. However, postcodes with the same second digit do not always form to a geographically contiguous area. As an example, postcodes in the range 2200—2299 are split between the southern suburbs of Sydney and the Central Coast of New South Wales.

Postcodes with a second digit of "0" or "1" are almost always located within the metropolitan area of the state's capital city. Postcodes with higher second digits are usually located in rural and regional areas. Common exceptions are where towns were considered 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 digit, postcodes tend to increase 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:

Town Postcode Distance from Central Station[4]
Dungog 2420 245km
Taree 2430 378km
Kempsey 2440 503km
Coffs Harbour 2450 607km
Grafton 2460 695km
Casino 2470 805km

Major towns and cities

Major towns and cities tend to have "0" as the last digit or last two digits, e.g. Rockhampton, Queensland has the postcode 4700 and Ballarat, Victoria has the postcode 3350. There are exceptions; for instance, the major town of Ipswich, Queensland has the postcode 4305, while Goodna, a relatively unimportant suburb of Ipswich, is allocated 4300.

Postcode Squares

Post Office Preferred envelopes sold in Australia contain four squares in the bottom right corner of the front of the envelope. These squares, referred to by Australia Post as Postcode Squares, contain the destination postcode for hand-addressed mail. This is for the purpose of Australia Post's automated mail-sorting equipment, which uses optical character recognition software. Postcode Squares were introduced in 1990.

Australia Post recommends that Postcode Squares should not be used for machine-addressed mail, or mail destined overseas.

Other uses

Since their introduction, many organisations other than Australia Post have used postcodes in their operations. Insurance companies often use postcodes when calculating car and house insurance premiums. The NSW Ministry of Transport uses postcodes to assign specific numbers for each bus stop in Greater Sydney. The stop number is five to seven digits: the first four being the postcode, with the remainder identifying the specific stop (sometimes written with a space in between, eg. "2000 108"). Many companies that produce metropolitan street directories also list the postcodes for each suburb, both in indexes on the maps themselves.

Mechanised sorting

To improve the efficiency of mechanised sorting, each address now has a sorting number which is printed on the letter as an orange coloured barcode. This number might be 12 digits long. This system enables the delivery officer to place items in delivery order.

Simple English

Postcodes are used in Australia to sort and send mail to the correct address. All postcodes in Australia have four numbers and are placed at the end of the address. Australian postcodes are managed by Australia Post.

Postcodes are published in small books which can be collected from your nearest post offices, or online at the Australia Post website.

On envelopes and postcards there are often four square boxes printed in orange ink at the bottom right for the postcode numbers. These are used when addressing mail by hand.

History

Postcodes were started in Australia in 1967 by the Postmaster-General's Department (PMG), now called Australia Post. They replaced earlier postal sorting systems, such as Melbourne's letter and number codes (e.g., N3, E5) and a similar system once used in rural and regional New South Wales.

Format

Australian Postcodes are four numbers, and written after the name of the city, suburb, or town, and the state or territory:

Mr John Smith
200 Flinders Street
MELBOURNE VIC 3000

When writing an address by hand, a row of four boxes (pre-printed on the lower right hand corner of many envelopes) is usually used.

Geography

Australian postcodes are sorting information. They are often linked with one area (e.g. 6160 belongs only to Fremantle, Western Australia). But sometimes they can be quite complex, especially in country areas (e.g. 2570 belongs to twenty-two towns and suburbs around Camden, New South Wales). 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 the City of Toowoomba), while other postcodes have much smaller populations, even in urban areas. The postcode numbers range from as low as 0200 (for the Australian National University) to 9729 (mail addressed to the Gold Coast City Council).

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:

Mr John Smith
99 George Street
PARRAMATTA NSW 2150

But mail sent to a PO Box in Parramatta would be addressed:

Mr John Smith
PO Box 99
PARRAMATTA NSW 2124

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.

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.

External territories

Australia's external territories are also included in Australia Post's postcode system. While these territories do not belong to any state, they are addressed as such for mail sorting:

State and territory capital cities

Each state's capital city ends with three zeroes, while territorial capital cities end with two zeroes. Capital city postcodes were the lowest postcodes in their state or territory range, before new ranges for LVRs and PO Boxes were made available. The last number can usually be changed from "0" to "1" to get the postcode for General Post Office boxes in any capital city (though Perth now uses a different range of postcodes for its GPO Boxes):

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 othera. 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 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:

TownPostcodeDistance from Central Station
Dungog2420245 km
Taree2430378 km
Kempsey2440503 km
Coffs Harbour2450607 km
Grafton2460695 km
Casino2470805 km

Major towns and cities

Major towns and cities tend to have "0" as the last number or last two numbers, e.g. Rockhampton, Queensland 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.

Postcode squares

Post Office Preferred envelopes sold in Australia have four boxes in the bottom right corner of the front of the envelope. These boxes or squares, which by Australia Post calls postcode squares, have the postcode for hand-addressed mail. This is for the purpose of Australia Post's automated mail-sorting equipment, which uses optical character recognition software. Postcode squares were introduced in 1990.[needs proof]

Australia Post says that postcode squares should not be used for machine-addressed mail, or mail going overseas.

Other uses

Many other organisations now use postcodes. Insurance 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, eg. "2000 108"). Many companies that produce metropolitan street maps also list the postcodes for each suburb, both in indexes on the maps themselves.

Mechanised sorting

To improve mechanised sorting, each address now has a sorting number which is printed on the letter as an orange coloured barcode. This number might be 12 numbers long. This system enables the post office to place items in delivery order.
