In Brazil, the Penal Code states that anyone who commits the crime of false identity does so to obtain an illicit advantage for their own benefit or that of another person, generally to cause harm to another person or establishment. The penalty for this is moderate and varies from three months to one year, or a fine if the act does not constitute an element of a more serious crime.
