    Supporting documents
    6 (a)Have national explanatory notes and/or guidelines been elaborated?Previous to CNAE there was not an uniform national classification, but different tables of codes and denominations for economic activities used for specific aims of specific users.

    At IBGE: previous to CNAE:
    - Classificação do Censo Agropecuário (Agricultural Census Classification - 1985,): a list of codes and activities;
    - Classificação de Atividades econômicas dos Censos Econômicos - 1985 (Economic Census Classification - 1985), covering mining, manufacturing, construction, trade and part of the services.

    6 (b)Do correspondence tables exist between the national and the international classifications (if applicable)?Link between previous IBGE classifications and ISIC Rev2 was not precisely defined. For mining and manufacturing there was a correspondence table at the most detailed level.
    6 (c)Are correspondence tables between alternative and current classification available (if applicable)?Economic Census Activity Classification for mining, manufacturing, construction, wholesale and retail trade and part of the services activities(which were covered by the Economic Census): 4 levels
    6 (d)Does a national coding index exist?Number of items at the most detailed level:
    Mining and manufacturing - 690 items
    Construction - 43 items
    Trade - 369 items
    Transportation - 22 items
    Services (covered by the Census) - 163 items
    6 (e)Is the classification available in electronic form? If yes, in which formats is it available?(e.g. PDF, TXT, Excel, XML)Yes. But there are many cases of n to n correspondence. Changes between CNAE and the previous classifications are due mainly to the decision to build CNAE as a derived ISIC classification.
    6 (f)Are the correspondence tables or indexes available in electronic form?1985, in the Economic Census
