Belgian national identity card
All fields on the card are bilingual (English in combination with either Dutch, French or German) and the heading "Belgium / Identity card" in all four languages. The used language (and the one used first in the heading) depends on the official language of the place of residence (per the Belgian language areas), unless the residence is a Brussels municipality, in which case the holder may choose between French or Dutch, or a municipality with language facilities, in which case the holder may choose between French or Dutch, or French or German, depending on the local language facilities.
