Classificação Portuguesa das Atividades Económicas
The code for a type of economic activity in Portugal. It states what a business or sole trader does, and it comes up when opening atividade, changing your details and on some forms. What matters for an ordinary person is to choose the code closest to what you actually do, so that you do not have to change it later.
Where you come across it. Opening atividade or filing an Alteração de atividade at Finanças, registering a business.
Do not confuse it with the profession codes in the tabela do artigo 151.º do CIRS: they are not the same thing.
