AU Business Identity
Deterministic Australian business identifier validation for AI agents and applications.
Part of AU Agent Utilities.
What it does
AU Business Identity currently validates Australian:
- ABNs — Australian Business Numbers
- ACNs — Australian Company Numbers
Validation is performed locally using the official checksum rules.
It does not yet confirm whether an ABN or ACN is registered, active or associated with a particular entity.
Registry verification and Australian business lookup tools are planned next.
