What the provider number is for
When a provider is registered with the NDIS Quality and Safeguards Commission, it is also set up in the NDIA's systems so it can work with participants and be paid. The provider number, often called the provider registration number, is how the NDIA identifies that business.
You will see it used in a few places:
- Logging in to the NDIA's provider portals for the first time, together with your ABN
- Making claims and payment requests for agency managed participants
- Being recorded as a my provider for a participant, where the participant may give the NDIA your provider registration number, ABN and business names
- On quotes, service agreements and invoices, so participants and plan managers can match you to the right business
Provider number, registration ID and ABN
These are easy to mix up:
- ABN: your Australian Business Number from the Australian Business Register. Every NDIS provider, registered or not, needs one to invoice
- NDIS provider number: the number registered providers use in the NDIA's systems for claims and portal access
- Registration details with the NDIS Commission: your certificate of registration, registration groups and expiry date, managed in the NDIS Commission Portal
- Worker screening ID: belongs to an individual worker, not the business
Do unregistered providers get a provider number?
No. Unregistered providers are not set up in the NDIA's provider systems in the same way, cannot work with agency managed funding and do not claim from the NDIA directly. They invoice self managed participants, or plan managers on behalf of plan managed participants, using their ABN.
This is changing. From 1 July 2027 a new provider enrolment system starts, requiring a minimum level of identifying information from most NDIS providers, with everyone in scope enrolled by December 2027. Watch for details of what enrolled providers will receive.
How to check a provider is registered
A provider number on an invoice is not proof of current registration. The reliable check is the NDIS Commission's Find a registered provider search, which you can search by business name, legal name or ABN. A current registration shows as Approved, with the registration groups the provider can deliver.
For SIL and NDIS digital platforms, the Commission also publishes a list of providers who applied for registration before 1 October 2026 and can keep delivering while their application is assessed.
For providers: keeping your number working
Your registration is tied to a single ABN. If your business structure changes and you get a new ABN, the NDIS Commission treats it as a new registration application, not a renewal. Notify the Commission of changes to your business name, structure or ownership through the NDIS Commission Portal.
If your registration lapses, you cannot be paid for supports that need registration, such as work with agency managed participants. Start re registration within the 6 months before your expiry date so your registration stays valid while it is assessed.
