Get ASIC document details by document number

Look up any ASIC document number to get the form code, lodgement dates, page count, imaging status, related parties and the company it was lodged for.

Every form lodged with ASIC, from a Form 201 company registration to a Form 484 change of details or a Form 505 appointment of a liquidator, is given a 9-character ASIC document number. Company extracts, person extracts and weekly summaries all cite these numbers. This endpoint resolves a document number into its details: the form code and title, when ASIC received and processed it, how many pages the scanned image has, whether it is available to order, and the company and people the document relates to. Use it to validate a document number before ordering the image, or to discover which company a document belongs to when all you have is the number. It is a free lookup: ASIC charges only when you order the image, as explained in the purchasing guide.

Batch request

Look up as many as ten document numbers in one call. The response is a list whose items are either a document or, where ASIC rejected that particular number, an error entry, so one bad number does not fail the whole request.

The batch call returns HTTP 200 whenever the request itself was valid, even if every item is an error entry. Request-level problems such as a malformed or duplicated number are returned as a normal error response with HTTP 400 and nothing is looked up.

Errors

Notes from the ASIC register

  • Public documents only. ASIC returns details for publicly accessible documents. Documents that are exempt from public inspection, or that were lodged with a state authority before ASIC existed and never migrated, return document_not_found.
  • Imaging. Document images are available for imaged, publicly accessible ASIC documents. Where ASIC's image page count is zero, the document is not currently available for retrieval and imaged is false; ordering it returns document_not_imaged. Documents lodged in the last day or two may show 0 until scanning completes.
  • XBRL files. Details of an XBRL document can only be obtained through the original document's number. Looking up the number in xbrlDocumentNumber directly returns document_not_found; the XBRL file is delivered together with the original when you order its image.
  • Organisation number headings. Organisations on the ASIC database are allocated a unique number whose heading depends on the type: ACN for Australian companies registered under the Corporations Act 2001, ARBN for registered bodies, ARSN for managed investment schemes, and plain Number for other entities. numberType carries the heading so you can display the number correctly.
  • Related parties are indexed names. ASIC indexes the parties named on the form, but the list is not a structured record of what changed. A Form 484 appointing a director will name the company and the director; the appointment date and role are on the company's office holders.
  • Free. Document detail lookups carry no ASIC fee, so call this endpoint as often as you like. The fee applies when you place an image order, which is charged when ASIC accepts the order. See the purchasing guide.
  • Sandbox. With a test key, only documents of ASIC's sample company 009 136 109 return details; other numbers return document_not_found.
