Chile contains the administrative territorial entity Arica y Parinacota Region
Administrative divisions
In 1978 Chile was administratively divided into regions, and in 1979 subdivided into provinces and these into communes. In total the country has 16 regions, 56 provinces and 348 communes.Each region was designated by a name and a Roman numeral assigned from north to south, except for the Santiago Metropolitan Region, which did not have a number. The creation of two new regions in 2007, Arica and Parinacota (XV) and Los Ríos (XIV), and a third region in 2018, Ñuble (XVI) made this numbering lose its original order meaning.
