Base Empresarial is a free online platform for searching and exploring information about Brazilian businesses. Using open data published by Brazil’s Federal Revenue Service, it provides access to a database of more than 69 million companies, including active and inactive registrations. Users can search by company name, trade name, CNPJ number, location, or business activity, and view details such as registration status, address, economic activities, legal structure, company size, capital, opening date, and partners. Data is updated monthly to follow the Revenue Service’s releases.

The platform also helps users understand the wider business landscape through statistics and rankings for Brazil’s regions, states, municipalities, capitals, and economic activities. Its advanced filters combine criteria such as CNAE activity, location, company size, and registration status. Other resources include a browsable CNAE catalogue, business-opening and survival trends, comparisons between periods, and a public API for accessing company and statistical data. Searches and browsing are available without registration; a free account lets users save recurring searches and download results as spreadsheets.
