A list of partners/shareholders (socios) of the specified Brazilian company, each with partner name, type (individual, company, or foreign entity), masked CPF or tax document, qualification/role code and description, entry date into the partnership, and age bracket. Data sourced directly from the official Receita Federal CNPJ registry.
Example use cases
Verify ownership of Brazilian supplier
“We're onboarding a new supplier in Brazil and I need to verify who actually owns the business before we sign anything. Can you look up the partners and shareholders listed in the Receita Federal registry for CNPJ 12.345.678/0001-99 and tell me their names, roles, and when they joined the company?”
Due diligence on Brazilian investment target
“We're considering investing in a Brazilian company and I need to understand its ownership structure first. Can you pull the full list of socios from the Receita Federal for CNPJ 45.678.901/0001-23, including each partner's type, qualification, and entry date?”
Flag undisclosed partners in KYB review
“I'm running a KYB check and the Brazilian company we're reviewing claims to have only two owners, but I want to verify that against the official registry. Can you fetch the list of partners and shareholders for CNPJ 98.765.432/0001-10 from the Receita Federal so I can cross-check what they disclosed?”
Technical details
Endpoint
GEThttps://api.brazilayer.com/v1/cnpj/empresa/:cnpj/sociosWhen to prefer
Use this endpoint when you need to enumerate the specific partners, shareholders, or owners of a known Brazilian company identified by CNPJ. Prefer this over the full bundle endpoint when you only need ownership data (not full registration details) to minimize cost. Prefer over a reverse-lookup endpoint when you are starting from a company CNPJ rather than a person's identity.
Side effects
- Invalid or malformed CNPJ returns a 400 or validation error
- CNPJ not found in Receita Federal registry returns 404 or empty result
- Company exists but has no registered partners (e.g. government entities) returns empty socios list
- Temporary upstream Receita Federal unavailability may cause 503 or timeout
- Rate limiting may apply if called in rapid succession
