CNPJ Lookup — Free Company Search in Receita Federal Database

Search any Brazilian company by CNPJ and get complete registration data from the Receita Federal — company name, trade name, address, CNAE (economic activity code), registration status, incorporation date, share capital, company size, and the full list of partners (QSA) — all for free and without registration.

Our CNPJ lookup tool uses official open data from the Receita Federal do Brasil, published under the Creative Commons CC-BY license as mandated by Decree 8.777/2016. The data includes over 60 million registered companies and is updated monthly from the Federal Revenue Service open data files available at dados.gov.br.

In compliance with LGPD (Lei Geral de Proteção de Dados), CPF numbers of individual partners are automatically masked in the format ***.XXX.XXX-**, protecting personal data while still providing useful information about the company's ownership structure.

Each result displays the complete QSA (Quadro de Sócios e Administradores), including partner names, document numbers, roles, and entry dates. For corporate partners (CNPJ), the full number is shown formatted. The registration status badge uses color coding — green for active, red for closed, and yellow for other statuses — making it easy to quickly assess the company's current standing with the Receita Federal.

This tool is essential for due diligence, supplier verification, fraud prevention, and general company research. Whether you are a developer, accountant, lawyer, or business owner, you can quickly verify any CNPJ and access the same data available at the official Receita Federal website. The tool also supports the new alphanumeric CNPJ format introduced by IN RFB 2.119/2022, effective July 2026. Try also our CNPJ Validator and CNPJ Generator (for testing).

Frequently Asked Questions

Where does the CNPJ data come from?
The data comes from the official open data published by the Receita Federal do Brasil (Brazilian Federal Revenue Service), available at dados.gov.br under the Creative Commons CC-BY license as mandated by Decree 8.777/2016. Our database is updated monthly from these official files.
Why are some CPF numbers masked?
In compliance with LGPD (Brazil's General Data Protection Law), CPF numbers of individual partners (pessoas físicas) are automatically masked in the format ***.XXX.XXX-**. This protects personal data while still showing the company's ownership structure. CNPJ numbers of corporate partners are displayed in full.
Can I search for alphanumeric CNPJs?
Yes. Our tool supports both traditional numeric CNPJs and the new alphanumeric format introduced by IN RFB 2.119/2022, which will take effect in July 2026. Simply enter the 14-character CNPJ with or without formatting.
