Cadastro PJ, powered by LinkWS, provides company registration lookups and business information tools for individuals and professionals in Brazil. Users can search by CNPJ, trade name, legal name, phone number, or email to access essential company details, including registration status, business activity classification (CNAE), city, and state. The service also offers expanded company profiles with information such as branches, partners, contact details, and share capital.

For more extensive research, Cadastro PJ supports batch searches: users can submit a list of CNPJs and download company data in Excel, HTML, or CSV formats. Account features include consultation history, organized reports, management tools, and access to additional data, with professional resources available through licenses and credits. The site describes its approach as focused on privacy, clarity, and professional use, and states that its company records come from public data provided by Brazil’s Federal Revenue Service. Cadastro PJ also provides customer support by phone and contact form during weekday business hours.
