091 numbers in Australia (+61 91)
What the numbering plan and the regulator's allocation table say about numbers starting 091 (+61 91): the place, the line types, every block's status and the carriers those blocks were allocated to. Original allocation, not who serves a number today, and never who owns or calls from a number.

Blocks in the regulator's table
Each block is a 3-digit prefix of the national number. A number in an allocated block is assignable; in an unassigned block no carrier can have a subscriber, so the lookup answers unassigned_block for it, except a number in a range reserved for fiction (is_fictional), which answers valid even where the regulator lists its block as protected.
| Allocated | 2 |
|---|---|
| Unassigned | 8 |
| Reserved | 0 |
| Total blocks | 10 |
Who the blocks were allocated to
The holders as the regulator lists them, by number of allocated blocks. Allocation is not service: a ported number keeps its original block, so a holder here may no longer serve a given number.

How to read this page
Everything above comes from two public sources: the numbering metadata, which names the zones and the line types of the range and, outside North America, its place; and the regulator's allocation table, which lists each block's status and holder and, in North America, the rate centres the place is named from. Neither knows who serves a number today, whether a handset is switched on, or who owns or answers it. Spaw reports what the tables say and names the dataset and version behind every answer.
