Need a one-off check? Check one contractor.
Procurement approval
Check licence status before a contractor or provider is approved or retained.
Site access
Confirm the contractor has the relevant state licence before work begins.
Panel review
Review contractor licence lists when panels or preferred-provider records are refreshed.
Decision fit
Where this API path helps
Use this path for supplier and subcontractor onboarding: match the licence holder to the contracting entity, retain the available scope and source evidence, and refer unresolved matches or unavailable records for review. Keep project insurance and approval decisions separate from the licence response.
Source proof
Coverage evidence for decisions
Contractor coverage is split by state and source family so WorkClear can safely represent which official registers are live today.

Common questions
API buying context
Can WorkClear verify contractor licences across current live coverage?
WorkClear has live public contractor coverage across Australian states and territories, with clear caveats for specialised or not-yet-live source families.
Does the contractor API include South Australia?
Yes. South Australia is live for active CBS PGE and Builder/BLD contractor records, while broader SA categories are handled separately.
Can I search by ABN?
ABN search is supported where register data contains usable ABN details. Exact licence number and holder-name search remain the most reliable inputs.
