Introduction of Area Codes (pre-1990s)[edit]

The introduction of subscriber trunk dialling was slow, partly because of the distances of exchanges in some areas and partly due to the use of manual exchanges well into the 1980s. Initially, area codes covered a very small area, sometimes only one exchange, but gradually exchanges conglomerated to become area codes. Length of codes vary, from two digits in large centres like Sydney to over five digits in smaller areas.

The digit following the leading zero was chosen to represent a rough geographic area, with following numbers

* Until 1994, these territories were not part of the Australian numbering plan, and instead used the code 672, for the Australian External Territories of Norfolk Island and the Australian Antarctic Territory. Numbers in use before 1994 are now in the number ranges of 08 9162 for Christmas Island and 08 9164 for the Cocos Keeling Islands, but other ranges are now used on the islands (at least in theory).

By 1994, there were 6 area codes of two digits covering Sydney (02), Melbourne (03), Canberra (06), Brisbane (07), Adelaide (08) and Perth (09), 48 area codes of three digits, from (002) covering Hobart to (099) covering mid-west Western Australia, and one area code of four digits, Kangaroo Island (0848), which was not incorporated into a larger area code before 1994.

To dial these numbers from overseas, one omitted the leading zero. In the case of numbers in the 00 range, only the first zero was omitted: Hobart was +61 02 xxx xxx - this was a potential cause of confusion with the Sydney area code, even with a differing number length. The 007 range was used for satellite phones and "0G" mobile phones.[1] Even as late as 2005 there was confusion: the prefixes +61 78 and +61 79 were listed as a "mobile phone number" on some call rates,[2] even though the prefix was +61 07x and had not been used for over a decade.

Renumbering (1994-1998)[edit]

In Australia, as in other countries, due to the increase in subscriber uptake of services such as extra telephone lines in homes, mobile phones and other services, the previous numbering plan was being stretched to its limit. It was decided to reduce the number of area codes and lengthen all subscriber numbers by one or two digits. This occurred between 1994 and 1998, and was done progressively to ensure as little inconvenience and confusion as possible. The gradual change was also to avoid number clashes, a situation where two subscribers in two completely different locations have technically the same telephone number if dialled in their entirety.

In almost all cases, the former area code was incorporated into the new subscriber number: Canberra numbers went from (06) 2xx xxx to (02) 62xx xxxx, numbers in the Northern Territory went from (089) xxx xxx to (08) 89xx xxxx, and so on. The four major exceptions were the two cities of Sydney and Melbourne, which added a 9 to the beginning of subscriber numbers; Tasmania, which became part of the (03) 6xxx xxxx range; and Queensland, which spread its area codes across a wide number range so that (07) 3... covers Brisbane, (07) 5... covers the surrounds including Esk and the Gold and Sunshine coasts, and (07) 4... covers the rest of the state.

During the period of changeover, Australians were often told they were required to dial the entire telephone number they were calling, including the area code, even though the number may have been within the same area code. For example, a caller in Sydney with the number (02) 9xxx xxxx would need to dial (02) 49xx xxxx to call a number in Newcastle, despite the area code being the same. This was in order to avoid possible number clashes. Although this practice officially ceased on 1 March 1999, many still believe they are required to dial an area code outside their own telephone book area, but this is not the case.

  1. ^ The Canberra area code was formerly (062) but, due to demand, incorporated the 2 into the subscriber number during the early 1990s. Despite this, the area code was still listed as (062) is some areas before the change to eight digits.
  2. ^ Brisbane local numbers were only available in the forms 2xx xxxx, 3xx xxxx or 8xx xxxx so that outside dialling could not clash with other area codes.
  3. ^ Adelaide local numbers were only available in the forms 2xx xxxx, 3xx xxxx, 3xx xxx, 4xx xxxx or 4xx xxx so that outside dialling could not clash with other area codes.
  4. ^ Perth local numbers were only available in the forms 2xx xxxx, 3xx xxxx, 4xx xxxx or 5xx xxxx so that outside dialling could not clash with other area codes.

Minor Changes[edit]

Kangaroo Island was the only area in Australia that wasn't integrated into a larger area code before the change to eight-digit phone numbering, and had the only four-digit area code, (0848). The Kangaroo Island area was incorporated into the (08) 855x xxxx number range with a significant change to subscriber numbers (for example (0848) 21 000 became (08) 8553 0000).

In order to prevent incorrect connections during the changeover period, a number which would otherwise have the first digits of its old form the same as the first digits of its new form had to be changed. For example, (043) 432 123 may be confused with (02) 4321 2345 (which would be used for (043) 212 345) during the change. To prevent this, before the change to eight digits, the local number was changed, so that, in the example, (043) 432 123 would become (043) 442 123, and then (02) 4344 2123. A list of all numbers changed in this way is shown in the table below.
