How to find a business's ANZSIC code
The ABR doesn't record an industry code, so you can't look one up like an ABN. Here's how to get a reliable ANZSIC code for a business — one at a time or in bulk.
This is the question that trips people up: you can look up a business's ABN, name, GST and location on the register — but not its industry. The Australian Business Register doesn't record an ANZSIC codeagainst a business. So “find the ANZSIC code” isn't a lookup; it's a classification. Here's how to get one you can trust.
Why there's no simple lookup
ANZSIC is the ABS's classification system, not a field on the ABN register. That means for any specific business, an ANZSIC code has to be inferredfrom what the register does hold — chiefly the registered names. Because it's inferred, the right question isn't just “what's the code” but “how confident is it.”
Find the code for one business
Search the business in the directory or resolve it with ABN / name matching. Each record shows a labelled ANZSIC division and class — for example E · 3231 · Plumbing Services — alongside a confidence score so you know how much weight to put on it. New to the structure? See ANZSIC codes explained.
Classify a whole list
If you have a book of customers or suppliers, do them all at once:
- Bulk CSV — upload names or ABNs and export the labelled division and class per row.
- API — classify programmatically, with asynchronous jobs for large files. See the API docs.
Use the confidence score
Treat the label as a prediction, not a fact. Auto-accept high-confidence rows, and route low-confidence ones to review or leave them unclassified rather than guessing. That's how you segment a portfolio by industry without silently miscategorising the hard cases.

Frequently asked
- Can I look up a business's ANZSIC code by ABN?
- Not from the register — the ABR doesn't store an industry code against an ABN. ABR Insights labels one from the business's registered details and shows it with a confidence score.
- Why isn't the ANZSIC code official?
- Because the register doesn't publish industry, any code attached to a specific business is inferred, not recorded by the ABR. It should be treated as a prediction, which is why a confidence score matters.
- Can I classify a whole list of businesses?
- Yes. Match a CSV of names or ABNs, or use the API, and each row comes back with a labelled ANZSIC division and class.
