Phone numbers in Australia (+61)

+61 is the calling code of Australia. The trunk prefix is 0 and the international prefix 0011. Every mobile number starts with 04 when written nationally, with the trunk prefix, and no other type of number in the plan does. Read from libphonenumber’s numbering metadata (release 9.0.41) and the ACMA numbering register of 2026-10-19, never from a number anyone typed.

Dialling and writing numbers in Australia

The trunk prefix is dialled in front of a number inside the country and dropped after the calling code; the international prefix is dialled to call out of it. The lengths and the leading digits below say which numbers the plan accepts and what their first digits tell you about the line type.

Lengths count the national significant number, the digits after the calling code, without the trunk prefix. Every value is read from libphonenumber’s metadata, release 9.0.41, which a lookup runs on.

The numbering plan for Australia

Every phone lookup starts from the numbering metadata: it settles whether a number is valid for Australia, how it is written nationally and internationally, and which line type its range belongs to. The example numbers below are libphonenumber’s examples of each line type’s format; one may be in service, so read them for their shape and never dial or text one as a test.

+61 is shared with Christmas Island, Cocos (Keeling) Islands, so the region of a number is settled by its area code, not by the calling code alone.

The regulator table behind a lookup here

ACMA numbering register (synced 2026-10-19, table version 2026-10-19). The table is partial: the regulator publishes only part of its plan in machine-readable form, so absence from it says nothing about a number and block_status stays null outside it. A lookup names the block holder as carrier with carrier_source block_allocation — the original allocation, never who serves the number today.

  • 99,624 blocks in the table: 90,794 allocated, 8,830 unassigned, 0 reserved.
  • 91.1 % of the blocks are allocated.
  • 100.0 % of allocated blocks name a holder.
  • 26.9 % of allocated blocks settle the line type on their own (444 mobile, 23,941 VoIP).

Measured weekly (last on 2026-10-25) from the table itself. These are shares of the regulator’s own table, not of real traffic, and they say nothing about who serves any one number today.

Who publishes the table, its files and terms, and what the copy installed here holds are on its data source page.

What a lookup answers for a number here

Every number the plan accepts for Australia comes back with its formats, its line_type and line_type_source, its region and timezones, and the is_fictional and is_disposable flags from the bundled fiction ranges and the synced list of SMS-receiving numbers. Because the ACMA numbering register covers Australia, a lookup also answers carrier from the block holder and block_status where the partial table has the block.

Several zones. Australia keeps more than one clock, so a lookup answers timezones per number from its area code and exchange where the plan settles it.

Area codes in Australia

Australia has 36 area-code pages; each reads the same table for the blocks under its code, their original holders and the line types they settle.
