Open https://publicdata.au/d/asic-business-names/latest/data.csv. It redirects to the newest dated version, which is https://publicdata.au/d/asic-business-names/v/2026-09-30/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 Business Names Register in Excel? Not as a workbook. Excel stops at 1,048,576 rows and this table has 3,327,008, 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-business-names/v/2026-09-30/data.csv.gz is the CSV at about a tenth of the size. ### What years does Business Names 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 Business Names 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 Business Names 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 Business Names Register? No. The publisher is Australian Securities and Investments Commission, and its page is https://data.gov.au/data/dataset/asic-business-names. 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, 2 files in the current version, listed with row counts at https://publicdata.au/d/asic-business-names/v/2026-09-30/by/status/index.json. For example https://publicdata.au/d/asic-business-names/v/2026-09-30/by/status/registered.json holds the 2,939,174 rows where status is Registered. ### 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 business names are in the file? Every business name registered with ASIC on the day the file was made, and every name deregistered in the twelve months before it. Each row is one name with its status, the date it was registered, the date it was cancelled if it has been, and the ABN of its holder when ASIC holds one. ### Is this the whole ASIC register? No. ASIC publishes selected public fields from its Business Names register once a week. The holder's name, address and the register's other details are not in the file and are found through ASIC Connect. ### Why are some names deregistered? A name is deregistered when its holder cancels it or ASIC cancels it, for example when the renewal fee is not paid. The publisher keeps deregistered names in the file for twelve months, with the cancellation date. ### What are the state registration number and state of registration? Business names were registered by each state and territory until the national register began in 2012. A name carried across from a state register keeps the number that state gave it and the state that gave it. Names registered nationally since then have neither. ## 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-business-names.yaml](https://github.com/National-Digital/publicdata.au/blob/main/register/asic-business-names.yaml) on GitHub, and a fix to it is welcome as a pull request. https://publicdata.au/contribute/ explains how.
