Brazil SMS messaging regulations and restrictions

Before you start sending SMS messages to Brazil, there are a few things you need to take into consideration. The from address (Sender ID) may be changed to a local number to provide optimal delivery to Brazilian networks. Additional restrictions in message content and format can be viewed in the table below. You can also read more at the Agência Nacional de Telecomunicações.
