Legal Entity Resolver
Company domain in, the registered legal entity out: legal name, company number, jurisdiction, status, LEI and VAT number. Only returns a match when the legal names are identical after normalization, so an unresolved domain comes back null instead of a confidently wrong company number.
Use Cases
- Who buys it. Built for anyone who has a domain and needs the company behind it: KYB and onboarding, contracting and invoicing, sanctions screening, or telling apart similarly named companies before a deal.
- Clay enrichment column. Turn a domain into a registered company number and VAT ID for KYB, contracting, and invoicing workflows.
Features
- Legal name and company number, as the register spells them
- Jurisdiction and status, active or dissolved, straight from the register
- LEI, the 20 character global identifier
- VAT number, validated live against EU VIES
- A full audit trail of what was rejected and why
