CNAE 2.3ISIC Rev.4release 2026-10-10

CNAE (Classificação Nacional de Atividades Econômicas) is the activity classification every Brazilian company declares on its CNPJ. Version 2.3 has 1,359 subclasses. The official labels are Portuguese only; the tables below give each one in English, its ISIC Rev.4 equivalent and how many active companies in Brazil use it as their main activity (release 2026-10-10).

CNAE is built on ISIC, so the 21 sections (A to U) and the divisions match one to one. Below the division the two drift apart: 1,212 of the 1,359 subclasses map to a single ISIC class through IBGE's correspondence table; the others map to one ISIC division whose candidate classes are listed.
