How we prepared it

This is the Minas Gerais part of our national file, with the same preparation:

  • Source: Receita Federal do Brasil open CNPJ data (Dados Abertos CNPJ), September 2026 edition (cut-off date 14 September 2026). The Empresas, Estabelecimentos and Simples Nacional files are joined by base CNPJ, with the official CNAE, legal nature and municipality descriptions.
  • Of the 73,366,147 establishments in the register, 28,263,121 are active. We excluded 17,431,451 active establishments of natural persons: individual entrepreneurs (legal nature 213-5, which holds nearly all of the 13,738,467 active MEI establishments), group 4 (rural producer as a natural person, political candidate, individual real estate business) and companies whose legal name contains a CPF. 1,227 establishments of companies flagged as MEI in the Simples file are also excluded.
  • We also excluded 51,773 establishments based abroad, 124,813 political-party bodies (their contact is usually a person and reveals political affiliation) and 804,516 establishments without any valid phone or email.
  • Phones: area code (DDD) validated against Brazil's 67 codes, the ninth digit added to old 8-digit mobiles, filler numbers dropped, and the three phone fields merged without duplicates, in E.164 (+55). tiene_movil marks a mobile number.
  • Emails: lowercased and syntax-checked; 70,648 invalid or filler emails (naotem@, [email protected], [email protected]) and obvious domain typos (gmail.con, gmai.com) were removed.
  • Names without double spaces; asterisk-only trade names emptied; CEP as 00000-000. CNAE and legal nature descriptions are in Portuguese, as in the official classification.
  • No partners (QSA), CPF or shareholder data.
