Brazilian passport

The Brazilian passport is the official document for foreign travel issued by the Brazilian government, through the Brazilian Federal Police. It is unclear from the references so far whether Brazilian citizens need a current or expired passport in order to re-enter Brasil.
A new model was officially introduced in December 2006 that complies with both Mercosul and ICAO standards, but as of February 2009, the previous model, three decades old, is still being issued at some places. So, in practice there are two models.
As a rule, Brazilian passports are valid for five years from the date of issue. They cannot be renewed: a new passport must be obtained when the previous one has expired or a minimum validity period is required by the country to be visited.
However, Brazilian passports can be ordered by mail for a duration of 3 years at the Brazilian consulate that has jurisdiction over the person's residence in a foreign country. The instructions say that whether applying for a "new" passport or a "renewal", the same application is used.^[1]
Brazilian citizens do not need a passport when traveling to other Mercosul countries (Argentina, Paraguay and Uruguay), as well as to Bolivia, Colombia, Peru or Chile. For these countries, they may use just their domestic identification cards, issued by state governments.
