ABN verification API

Verify an Australian business in one call: ABN status, GST registration, entity type, ACN, business names, and ACNC charity status, straight from the official Australian Business Register, returned as clean JSON. We are building it now. Register your interest and tell us what you would pay.

What one call returns

A single JSON object, sourced from the official ABR, with the original attribution on every response:

{
  "abn": "51824753556",
  "abn_status": "Active",
  "abn_status_from": "2014-01-01",
  "entity_name": "EXAMPLE PTY LTD",
  "entity_type": "Australian Private Company",
  "acn": "824753556",
  "gst_registered": true,
  "gst_registered_from": "2014-01-01",
  "business_names": [
    "Example Trading Co"
  ],
  "acnc_registered": false,
  "source": "Australian Business Register",
  "retrieved_at": "2026-06-22T00:00:00Z"
}

What it is, and what it is not

It confirms that an ABN exists and its ABR-published status: active or cancelled, GST registration and date, entity type, ACN, registered and trading business names, and ACNC charity / DGR status.

It is not identity verification, KYC/AML, or ownership/director verification. The ABR does not publish director or beneficial-owner data, and the register itself is not a warranty of accuracy. For those checks, corroborate with other sources. We say this plainly because honesty is the product.

Who it is for

Use case	The job it does
Accounts payable and invoicing	Confirm a supplier's ABN is active and GST-registered before you pay, the data point behind no-ABN withholding.
Onboarding and marketplaces	Verify a business at sign-up instead of trusting a typed-in ABN.
Accounting and payroll software	Validate and enrich an ABN inside your own product, with one clean call rather than the ABR SOAP service.
Status monitoring	Get notified when a supplier's ABN or GST status changes, instead of re-checking by hand.

Why not just use the free ABR?

You can, and for a one-off check you should. The official register is free. This is for teams that would rather not build and maintain a SOAP integration, want a clean JSON response with an SLA, bulk checks, status-change monitoring, and an MCP tool for AI agents. We sell the convenience and the upkeep, not the data, which stays the public ABR data it always was.

Try the format check now, free, in your browser

Paste an ABN to validate its format and checksum instantly (this runs in your browser and catches typos). It does not yet confirm the ABN is registered or its GST status: that is the early-access API.

Indicative pricing

Pricing is indicative while we validate demand. Tell us what would actually work for you.

Free: a small monthly allowance, no card, to try it.
Paid: a low monthly fee for higher volume, bulk checks, and status-change monitoring.
