Make sense of Belgium’s bilingual administrative language

Find the Dutch name, French equivalent or acronym printed on the document in front of you.

Belgian paperwork often presents the same institution or concept in Dutch and French, sometimes with a separate acronym for each. Search either version, start with an English concept, or browse practical subjects to understand what the term refers to and which authority or document it should not be confused with.
