How this service works
Reverse lookup: find every Brazilian company where a given person or entity appears as partner/shareholder, by name (full-text, accent-insensitive). Returns partner name, company CNPJ and legal name, role and entry date. The highest-value query for due diligence — data straight from the official Receita Federal CNPJ registry (personal tax IDs come pre-masked from the source). Free sample, no payment: https://api.brazilayer.com/v1/cnpj/amostra
Output
A paginated list of records from the official Receita Federal CNPJ registry, each containing the matched partner name, the company's CNPJ number and legal name, the partner's role (e.g. socio, administrador), and the date they joined the company. Personal tax IDs (CPFs) are pre-masked at the source.
Example use cases
KYC check on Brazilian supplier
“Before we sign this contract, I need to know every Brazilian company that 'Rodrigo Mendes Lima' is a partner or shareholder in — pull his full corporate footprint from the Receita Federal registry so our compliance team can review it.”
Map corporate network of entity
“Look up all Brazilian companies where 'Grupo Horizonte Participações Ltda' appears as a partner or shareholder in the CNPJ registry — I want the company names, CNPJs, the role they hold, and when they joined each one.”
Due diligence on acquisition target
“We're considering acquiring a company and I need to vet its founder — find every Brazilian business that 'Ana Paula Rodrigues Silveira' is listed as a partner or administrator in the Receita Federal database, including entry dates and roles.”
Technical details
Endpoint
GEThttps://api.brazilayer.com/v1/cnpj/socio/buscaWhen to prefer
Use this endpoint when you need to find all Brazilian companies associated with a specific individual or entity by name — the inverse of a CNPJ company lookup. Ideal for due diligence, KYC, compliance screening, or mapping corporate networks of Brazilian persons. Prefer this over company-by-CNPJ endpoints when you have a name but not a CNPJ, and need to discover all corporate affiliations.
Side effects
- Name string shorter than 3 characters returns a validation error
- No matching partners found returns an empty result set
- Ambiguous or common names return large result sets requiring pagination
- Network or upstream Receita Federal outage may cause 5xx errors
- Accent-insensitive search may still miss unusual name variants
