About ABN Signal
Who runs ABN Signal, why this site exists, and the scope it covers.
Summary
ABN Signal turns raw ABN register data into plain-language explanations and weekly change reports. Independent of any government body.
Who we are
ABN Signal is an independent data-intelligence project operated by Duy Pham, based in Melbourne, Victoria. Launched in 2026, the site focuses on one job: making Australian Business Number records easier to read and track over time.
The project draws on a background in data analysis and web-based reference products. ABN Signal exists to serve a single dataset with a single purpose — turning raw ABN register data into clear, readable information.
We are not part of any government agency. The Australian Business Register publishes ABN data as public records. We take that data, refresh it weekly, and add the context that raw fields do not provide on their own.
Why this site exists
ABN record data is public, but reading it well takes context. A field like "ABN status: Cancelled from 01 Jan 2026" raises questions the raw data does not answer. What does "Cancelled" actually mean? When did it change? What else changed at the same time?
That is the gap ABN Signal fills.
The site explains ABN record fields in plain language through guides and glossary pages. It runs weekly change detection — comparing full dataset snapshots to find what moved and when. Change feeds are live now, covering ABN status, GST status, and name changes. Individual record pages are planned for a future release.
Guides and glossary pages help non-experts make sense of what they see. A published methodology lays out exactly how the data is collected and processed.
Scope and boundaries
ABN Signal is an independent data-intelligence service — not a government registry. It is operated independently of the Australian Taxation Office and any regulatory body.
The site is purpose-built for:
- Weekly change detection across ABN and GST status fields
- Plain-language record explanations and guides
- Trend monitoring over time
It does not provide real-time data, legal or tax advice, full business profiles, or official regulatory determinations. The Australian Business Register remains the authoritative source for same-day record lookups.
Accountability and contact
If something on the site looks wrong — a data-display error, an interpretation you disagree with, or a freshness concern — use the corrections process to flag it. You can also reach us through the contact page.
Every correction is reviewed. Where we got it wrong, we fix it and note the change.
