Receita Federal do Brasil is the federal revenue service under the Ministério da Fazenda, and it keeps the Cadastro Nacional da Pessoa Jurídica, the CNPJ register in which companies, their branches, associations and public bodies in Brazil are enrolled. Its public window on that register is the query at solucoes.receita.fazenda.gov.br: type a CNPJ and the page issues the comprovante for that one establishment, stamped with the date and time in Brasília and carrying a QR code and a barcode.
From the comprovante, buttons lead to the Consulta Quadro de Sócios e Administradores, to the Condições de Dispensa de Licenciamento page that lists, for each exempt activity, the state or municipality, the issuing body, the scope and the conditions, and, for a closed registration, to the certidão de baixa. The page sits inside the Redesim portal for business registration.
Two traits set this register apart for a data buyer. It records establishments, not only companies, so one business can hold many records. And it is a tax registration rather than a corporate filing: no accounts and no shareholding percentages, but the registration status that banks, buyers and procurement teams look up before they deal with a Brazilian business, with a porte the company declares and CNAE codes for what it is registered to do.
