See the company behind any website: legal name, registration number, VAT & address. Check if a site is legit in one click. Ever wondered who is really behind a website? One click shows you the legal company operating any site: registered company name, registration number, VAT number, address, CEO, employees and revenue - straight from official trade registers covering 350M+ companies in 206 countries - including 26 million companies already matched to their website domain for instant, one-click identification. HOW IT WORKS 1. Open any website and click the extension icon. 2. The extension reads the page's own footer, imprint and structured data for a company name, registration number or VAT number, and verifies it against official registers. 3. No owner stated on the page? It falls back to WHOIS and IP ownership to identify the organization behind the domain - and always tells you which method produced the match. WHAT YOU GET - Website owner lookup: the legal entity, not a redacted WHOIS record - Website checker for online shopping: see if a webshop is run by a real, registered company before you pay - Company lookup by name or registration number, worldwide - Registration number, legal form, status, address, CEO, size and revenue - Full company reports on companydata.com COVERAGE: OFFICIAL REGISTERS IN 206 COUNTRIES Every match is verified against the official business register of the company's home country, including: - Netherlands: KVK (Chamber of Commerce), 3.8M registered businesses - United Kingdom: Companies House, 5.8M companies - Germany: Handelsregister (HRB) and EU VAT records, 2.9M businesses - France: SIRET / SIREN, 14.5M establishments - Belgium: KBO/CBE enterprise numbers, 2.3M businesses - United States: state business registrations, 41M records - Australia: ABN / ACN, 8.9M businesses - Brazil: CNPJ state registries, 27M businesses - Japan: Corporate Number registry, 6.5M companies - Italy, Spain, Poland, Czech Republic and 190+ more countries On top of the registers, 26M+ companies are pre-linked to their website domain (5.8M in the US, 2.7M in France, 1.8M in Germany, 1.7M in the Netherlands, 1.4M in the UK), so most lookups resolve instantly. And when a site is not in that mapping, the extension still identifies the owner from the registration or VAT number on the page itself. Whether you are checking a Dutch webshop, a UK supplier or a Brazilian manufacturer, the extension reads the local register and shows you the verified legal entity in one click.
