CAT A (Simple) & CAT C (Complex)

Porting requests in Australia are submitted one of two ways CAT A or CAT C.

CAT A (Simple) - Most common porting request. Used for single lines that are not associated to any type of “Complex Service”. Toll free and Shared Cost numbers are usually CAT A ports.

CAT C (Complex) - Porting request used when the requested numbers are part of a “Complex Service” (ISDN Services, Line Hunt, Fax Services, Number blocks, ADSL Services). Complex ports tend to have a longer lead time due to the complexity surrounding the process.

⚠️ If you are uncertain which category your porting request would be, we recommend contacting your current provider to confirm.
