Number Porting FAQ - Category A or C
Category A number ports are applicable only to single/standalone numbers delivered on...
- PSTN fixed phone lines (a standard, single port "phone plug in the wall" - the same as is typically found in a residential phone service) with no complex services (see below)
- NBN Phone services, where the service is delivered from the "Phone" ports on the NBN NTU
- Porting from most other VoIP providers (see below for exceptions)
Category C number ports are applicable to any numbers that...
- Are delivered over an ISDN / PRI service
- Are in a hunt group
- Are on a fax duet service
- Include a number range (10-range, 100-range, etc.)
- Are being ported from Telstra DOT (even if it's a single number)
- Are being ported from Optus Loop services
It may be possible to remove a specific number from a hunt group or fax duet service and port it as a Category A number. Please contact the current provider to see if this is possible.
If any of your numbers being ported require Category C porting, we generally recommend setting Category C for all of your numbers on the port.
This way, all of your numbers will be processed as a single port, so they will all fall under a single Category C porting cost and will be processed at the same time.
Category M number ports are applicable to any mobile numbers.
