Which port type to choose

Every port request has a port type. It decides what the form asks for and how the port is run. Choosing the wrong one gets the port rejected, and you will be asked to change it before it can continue.

Port type For Numbers start with
Single AU Geographic (CAT A) One geographic number with no complex features: a standard phone line. 02, 03, 07, 08
AU Geographic Range (CAT C) A range of geographic numbers, or a single number with complex features attached (such as an ISDN or a number range behind a PBX). 02, 03, 07, 08
Australian Mobile One mobile number. 04
Australian 1300 / 1800 A local-rate (13 or 1300) or freecall (1800) number. 13, 1300, 1800

The portal checks each number against the type you picked and refuses a number that can’t belong to it, such as an 04 number on a CAT A port.

Use CAT A for a single ordinary line. Use CAT C when:

  • you are porting more than one geographic number on the same losing account, or a block of numbers (10 or 100 in a row);
  • the number is the main number of a range, or has features such as hunt groups or ISDN attached on the losing carrier’s side.

If you aren’t sure, the losing provider’s bill usually shows whether the number is part of a range. A CAT C port can carry single numbers as well as ranges, so when a customer has several numbers, put them on one CAT C port rather than several CAT A ports.

A mobile port needs the person holding the number to confirm it: after you submit, we send a six-digit code by SMS to the number being ported (see Requesting a port). Identity is checked differently for the two kinds of mobile account:

  • Postpaid: the losing provider’s account number for the service.
  • Prepaid: the date of birth registered with the losing provider.

Supplying the wrong one is an immediate rejection from the losing carrier.

Local Number Portability lets a customer keep a number when they change provider, not when they move. A geographic number may not be able to follow a customer to a different area.
