Changes proposed for numbering

ACMA releases discussion paper for comment on proposed changes to telephone numbers in Australia

The Australian Communications and Media Authority (the ACMA) has today released a discussion paper seeking comment on three proposed changes to Australian phone numbers.

The proposals are set out in Numbering Variation 2012– understanding its effect on numbering. They include matters raised by the ACMA’s Numbering Work Program, which is examining Australia’s numbering arrangements. The proposals are:

  1. Supplement the supply of digital mobile numbers as the current supply of numbers (starting with ‘04’) may be exhausted as early as 2017
  2. Supplement the supply of geographic numbers in areas where the existing supply is expected to be exhausted within 20 years
  3. Remove the geographic sectors around capital cities from the Numbering Plan.

The ACMA has also made a variation to the Telecommunications Numbering Plan 1997, which includes the removal of six service types that are no longer required; removing unused portions of number ranges from six service types with limited use; amending the term ‘country code;’ and some other administrative improvements to the Numbering Plan.

This variation and the three proposals for discussion follow the ACMA’s decision to progress changes to the Numbering Plan via two variations.

Written submissions on the matters raised in Numbering Variation 2012– understanding its effect on numbering are welcome. The deadline is close of business, 17 February 2012.

Submissions should be sent either by email to or by post to Manager, Industry Partnerships and Numbering Section, Australian Communications and Media Authority, PO Box 13112, Law Courts, Melbourne, Victoria, 8010
