Hi Joao and Pedro,
Welcome to the Community! Thanks for starting this conversation and looking forward to seeing more users from Brazil post on this thread. Please note that you need to post your future comments in English, as per our Community Guidelines.
The Cadastro de Pessoas Físicas (CPF) is the the Brazilian individual taxpayer registry identification number. It has 11 digits and can be found on your CPF card.
You'll also need the branch number of your bank to register for Direct to Local Bank payments. The branch number is 4 or 5 digits with the format 0000 or 0000-0. Please confirm with your bank the correct branch number to use.
Happy to find this topic and hope to hear from you soon. I signed up to upwork few days ago, I read already lots of good things but I still have some questions. Please, any help will be very welcome! Thanks a lot!
