TELSTRA LIMITED

Allocations in the Australian numbering plan according to the ACMA register. The register's oldest allocation still held by TELSTRA LIMITED is dated 30 June 1991, its newest 15 October 2026. 5 of its ranges were originally allocated to another company — chiefly ONE.TEL LIMITED (3) and RSL COM AUSTRALIA PTY LIMITED (2). Conversely, 46 ranges first allocated to TELSTRA LIMITED are now held by other carriers. The register names the holder of each range; individual numbers may have been ported and operate on another network today.

Landline footprint

On the fixed network, TELSTRA LIMITED's 8,281 blocks add up to about 54,867,000 numbers across 2,099 numbering areas — around 43.0% of all allocated geographic numbering in Australia. The blocks are spread over 4 area codes: 2,533 under 02 (575 areas), 1,841 under 03 (475 areas), 1,894 under 07 (409 areas) and 2,013 under 08 (640 areas). The first landline block was allocated in 1991, the latest in 2026. Block size comes from the allocation register; it doesn't say how many numbers are actually in service.
