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, source date, and license attribution. These are company-level records only, with no person profiles or derived score.

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.

Source links: ASIC Company Dataset and Corporations Canada dataset, and Companies House Free Company Data Product.

Built on the authoritative federal record

The primary sources, named on every page.

These are the federal agencies whose public datasets Fonteum ingests and attributes — the issuing authorities, not customers or partners. Every figure on the site links back to one of them.

  • HHS-OIG
  • HRSA
  • FDA
  • NLM
  • NUCC
  • Census
  • BLS

Reproducible by design

Every figure traces to its federal source.

14-tuple provenance

Every rendered fact ties to a source URL, dataset ID, snapshot date, row key, and SHA-256 — the full chain-of-custody record.

Reproducible SQL

Each study ships the exact query behind its figures, run against the cited federal snapshot. Re-run it yourself.

Daily count checks

Published counts are checked against the upstream federal datasets on a daily cadence, with drift logged.
