ACMA announces changes to Numbering Plan

The Australian Communications and Media Authority (ACMA) has today announced that it has changed the Telecommunications Numbering Plan 2007.

The three major changes are:

• supplement the supply of digital mobile numbers with a new prefix starting with ‘05’
• supplement the supply of geographic numbers in regional areas where the existing supply is expected to be exhausted within 20 years
• remove the geographic sectors around five capital cities.

The most notable change is the introduction of the ’05’ prefix to new mobile numbers, which will supplement the existing ’04’ range of mobile numbers. This change has been driven by the ACMA’s prediction that an addition 100 million mobile numbers will be required over the next 20 years.
