SABCs ranked by number of free DE ranges

These tables show the number of DE ranges for each status, ordered by the number of free DE ranges in the SABC.

Allocated: Numbering capacity designated to the listed Operator.
Designated: Numbering capacity set aside for a future possible use, e.g. to protect blocks that might be used for migration.
Free: Numbering capacity which is not allocated at the time of publication of the list.
Protected: Where numbering capacity has been withdrawn from service, the block or code is sterilised for a period, typically 2 years. Alternatively the Numbering Unit might protect capacity for a limited period, to avoid dialling errors into similar codes.
