Company Lookup

Company data for UK, US & EU

Try with Claude

Company Lookup gives you full corporate intelligence on any UK, US, or EU company — directors, ownership, filings, charges, insolvency status, financials, and VAT validation — all from official registries in one place.

Pulling this information manually means visiting Companies House, SEC EDGAR, GLEIF, and several EU portals separately. This tool aggregates them all. It covers 5 million UK companies, all US public companies via SEC EDGAR, and 2.7 million global entities through the GLEIF LEI network. Financials are extracted from structured iXBRL accounts for UK companies and XBRL filings for US companies.

What you can do

  • search_companies — find companies by name across UK, US, and international registries
  • company_profile — full company details including directors, registered address, and status
  • filing_history — list of all statutory filings for a UK or US company
  • beneficial_owners — persons with significant control (UK PSC) or insider ownership (US)
  • charges — UK mortgage and charge registrations against a company
  • insolvency — UK liquidation, administration, and insolvency records
  • corporate_structure — parent/subsidiary mapping via the global LEI network
  • financial_data — structured balance sheet and P&L from iXBRL or XBRL filings
  • validate_vat — verify EU VAT numbers across all 27 member states

  • search_companies card titles now show the actual company name instead of "Unknown" — previously the card layer read a `title` field while the parsed search result returned `company_name`
  • search_companies now accepts UK Advanced Search filters: sic_codes, location, postal_code, status, incorporated_from, incorporated_to. Filters are applied server-side via /advanced-search/companies, and SIC codes come back populated on the result rows when these filters are used
