Bilhete de Identidade (Portugal)
Bilhete de Identidade (Identity Card), commonly abbreviated as BI, was the national identity card of Portugal. Established in 1919, the BI is gradually being replaced by the Cartão de Cidadão (Citizen Card) since 2008. BI's are valid for five years from date of issue for people under the age of 25, and then for ten years, and can be renewed 6 months before expiry. It is mandatory for all citizens above the age of 10, and available optionally for children.
Besides the Bilhetes de Identidade de Cidadão Nacional (National Citizen Identity Cards), the Portuguese authorities also issued Bilhetes de Identidade de Cidadão Estrangeiro (Foreign Citizen Identity Cards) for foreigners living in Portugal.
Since 2008 the Bilhete de Identidade and several other documents started to be phased out in favor of the single, more technologically advanced Cartão de Cidadão (Citizen Card). However, as of 2017, BIs continued to be issued in some cases.
