"Thank you for your continued patience.
We have received a reply from our processor and they have confirmed that in compliance with the new rules for bank account number and bank branch, account from Caixa has to be maximum 10 numbers. It is confirmed that the zeros in front of the account are not necessary.
Therefore if your account is for example "123456" there is no need to add zeros in front of the account and add only the necessary information,(example: 123456).
As a result, we have invalidated your account details from your Stars profile and you can re-submit your inquiry at your earliest convenience.
Regards,
Yavor

Em resumo, dizem que agora não precisa mais dos zeros à esquerda. Ainda não testei.
