Access to company data in Brazil - on a federal level - is very limited. In order to access data, one needs to know the identification number of the company. There is no service where people can search for the identification number if they only know the name. On a state level every state has a company registration agency that maintains company data. Data for the state of São Paulo is available here:

There is also a dataset of the government supplier registry that can be queried by name, has the legal name and identifier as well as addresses of companies. However, it is not updated regularly. Last update: January 2015. Companies that have never either laid bids for procurement with the government (mandatory) or just registered themselves (voluntarily) are not listed. Not available in bulk but is openly licensed.

Reviewer comments
