All communication with customers on Amazon.com.br must be carried out in Portuguese, the official language of Brazil. If you are not proficient in the language or do not have a member of your team fluent in Portuguese, you can use a translation tool or hire a service provider to manage communication with customers. If necessary, the partner can consult the Amazon Service Provider Network at Apps and Services > Explore Services , looking for the Account Management service type. Communication with customers must be clear and agile, in order to provide the best possible experience.
