Enter your registered business name and our tool will query the Australian Business Register in real time, returning your ABN along with your current registration status and business details. No account or payment is required.
Can I still use my ABN if I lost track of it?

Use our free lookup tool to retrieve it instantly and confirm your status before issuing any invoices.
What happens if my lost ABN has been cancelled?
If your search reveals that your ABN has been cancelled, you will need to submit a new application to the ABR before you can legally issue tax invoices or operate under that number. Our specialists can assess your eligibility, prepare your documentation, and manage the full reapplication process on your behalf to ensure approval first time.
How long does it take to recover a lost ABN?
Retrieving a lost ABN from the Australian Business Register is instant using our free lookup tool. If your ABN has been cancelled and requires reactivation or a fresh application, processing times vary depending on the ABR's review requirements. Our team monitors every application and keeps you updated at each stage until your number is fully restored.
