Brazil CNPJ Checker: Official Company Record by CNPJ Number

Look up a Brazilian company by its 14-digit CNPJ number (with or without dots, slash and dash): legal name, trade name, legal form, active or closed status, start date, address, CNAE industry code and size class, from the Receita Federal open data. Checks the CNPJ check digits first. Company-level only: no partners, no phones, no e-mail, no individual entrepreneurs (MEI).
