Global company registers

Company-level public register records

Fonteum's global company pages render public register facts for one company at a time: identifiers, status, registration dates, address fields, governing legislation, available source-date and license fields. Those fields vary by register record and can be null or absent. These are company-level records only, with no person profiles or derived score.

Register glossary

Definitions for the source families, identifiers, and bulk-data terms behind the global company-register pages.

Start with the source-scoped definition of an Australian Business Number (ABN); ABNs can identify structures beyond ASIC-registered companies.

How do I look up an Australian company by ABN/ACN?

Use the ACN when you have it; it is the company-register key in the loaded ASIC Company Dataset. The ABN appears when ASIC publishes it on the row. Fonteum exposes the record at /global/au/company/<acn>.

How do I look up a UK company by its company number?

Use the Companies House company number. Fonteum exposes the record at /global/uk/company/<number> and renders only public company-register facts from the loaded Companies House row.

Integrated, with-data, and fresh-observation counts are separate. No platform-wide source-completeness count is published. Completeness is source-specific and must be evaluated against the named source's expected scope. State coverage is a separate jurisdiction measure.

Source authority is record-specific

Use the issuer named on the record.

Fonteum spans federal, state, and global public publishers. A source page or returned record identifies its issuer and dataset where that metadata is available. A platform registry count does not assign every page to one authority or establish loaded, fresh, or complete coverage.

Reproducible by design

Inspect the evidence each published figure actually supplies.

Source and date

Research pages expose the named public file and observation date where those fields are available. Source-file SHA-256 coverage is separate; facts do not currently link deterministically to signatures.

Available derivation

Studies with a retained release and committed derivation link the SQL or method used. Other studies state the evidence and reproduction limits they actually have.

Daily observations

Dated table row-count observations can detect local drift. They do not imply that an upstream publisher released or Fonteum ingested new data that day.
