Cultural Tip
In Brazilian Portuguese, using 'preciso de' is already polite, but adding 'por favor' or switching to 'gostaria de' can make the request sound even more courteous, especially in formal emails or when speaking with someone you don’t know well. Also, remember that 'informação' can be both countable and uncountable, so the plural 'informações' is preferred when you expect several pieces of data.
