CNPJ.Today is a Brazilian business-data and market intelligence platform that organizes public information from the Federal Revenue Service of Brazil. It provides free online access to records for more than 73 million Brazilian business establishments, including registration status, business activities, share capital, location, and aggregated indicators about the ownership structure. The platform states that it does not publish partners’ names or personal documents.

Users can search for companies and browse business information by state and city, supporting regional market research and opportunity mapping. CNPJ.Today describes its data as official, nationally comprehensive, sourced from open government datasets, and automatically updated monthly; the displayed database is identified as updated for 2026. Its information may assist with market studies, responsible B2B prospecting, compliance, and supplier verification.

Additional offerings include a CLT-versus-PJ calculator to compare salaries and taxes, with more tools planned. The site also provides access to an API for developers and plans for corporate users.
