Open https://publicdata.au/d/asic-companies/latest/data.csv. It redirects to the newest dated version, which is https://publicdata.au/d/asic-companies/v/2026-09-29/data.csv today. The same path serves Parquet, SQLite, DuckDB, NDJSON, Arrow. A dated URL never changes, so use it when the file must stay the same. ### Can I open Company Register in Excel? Not as a workbook. Excel stops at 1,048,576 rows and this table has 4,448,915, so there is no data.xlsx. Load the CSV or the Parquet file with Power Query, or take one partition file at a time. https://publicdata.au/d/asic-companies/v/2026-09-29/data.csv.gz is the CSV at about a tenth of the size. ### What years does Company Register cover? The current version covers 1900 to 2025. Each release from ASIC becomes a new dated version here, and earlier versions stay online. ### How often is Company Register updated? ASIC releases it weekly. This site checks the portal every week and adds a dated version when the file changes. ### Can I use Company Register commercially? Yes. CC BY 3.0 AU allows commercial use, redistribution and derived works as long as the attribution is kept. The attribution string is in this page's side column and inside every file. ### Is this the official source for Company Register? No. The publisher is Australian Securities and Investments Commission, and its page is https://data.gov.au/data/dataset/asic-companies. This site republishes the publisher's file without changing its content. The original sits beside every version as source.zip with its SHA-256, so the two can be compared. ### How do I get only the rows for one status? Every version has one JSON file per value of status, 7 files in the current version, listed with row counts at https://publicdata.au/d/asic-companies/v/2026-09-29/by/status/index.json. For example https://publicdata.au/d/asic-companies/v/2026-09-29/by/status/regd.json holds the 4,127,243 rows where status is REGD. ### Why is there no query API for this dataset? Each weekly version is a table of millions of rows, and this site loads a version's rows into its query database only where they fit. The files carry the whole table in every format, and the Parquet file answers most questions in one read. ### Which companies are in the file? Every company registered with ASIC, with its type, class, sub-class and status, and the companies deregistered in recent years with their deregistration date. Each row is one company name, so a company that has changed its name has one row for each name it has held, and the current name indicator says which row is the name in force. ### What do the type, class, sub-class and status codes mean? The codes are ASIC's own. Type is APTY for an Australian proprietary company, APUB for an Australian public company, FNOS for a foreign company, RACN for a registered Australian body and CCIV for a corporate collective investment vehicle. Status is REGD for registered, DRGD for deregistered, EXAD for external administration, SOFF for strike-off action in progress, NOAC for not active, CNCL for cancelled and DISS for dissolved. The class and sub-class codes are set out in the publisher's help file on the source page. ### Why is the ABN blank for some companies? The publisher writes 0 where a company has no ABN. That 0 is kept here as a null value. ### Is this the whole ASIC register? No. ASIC publishes selected public fields from its company register once a week. Officeholders, addresses, share structure and documents are not in the file and are found through ASIC Connect. ## What this site did to the data Cells were typed, headers were renamed to snake_case and the encoding was made UTF-8. Rows were left alone. Nothing is derived. The publisher's file is beside every version as `source.zip`. ## Improve this dataset This page is built from [register/asic-companies.yaml](https://github.com/National-Digital/publicdata.au/blob/main/register/asic-companies.yaml) on GitHub, and a fix to it is welcome as a pull request. https://publicdata.au/contribute/ explains how.
