Blocks in the regulator's table
Each block is a 7-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. Of the allocated blocks, 1.2% belong to a wireless carrier, 3.5% to a virtual-number wholesaler or VoIP provider, and 95.3% to a holder whose name settles neither.

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 that names the place, the zones and the line types of the range, and the regulator's allocation table that lists each block's status and holder. Neither knows who serves a number today, whether a handset is switched on, or who answers it. Spaw reports what the tables say and names the dataset and version behind every answer.
