evidence: A province in Spain[note 1] is a territorial division defined as a collection of municipalities.[1][2][3] The current provinces of Spain correspond by and large to the provinces created under the purview of the 1833 territorial re-organization of Spain, with a similar predecessor from 1822 (during the Trienio Liberal) and an earlier precedent in the 1810 Napoleonic division of Spain into 84 prefectures.[4] There are many other groupings of municipalities that comprise the local government of Spain. [...] Provinces are also used as geographical references: for instance in postal addresses and telephone codes. National media will also frequently use the province to disambiguate small towns or communities whose names occur frequently throughout Spain. A small town would normally be identified as being in, say, Valladolid province rather than the autonomous community of Castile and León. In addition, organisations outside Spain use provinces for statistical analysis and policy making and in comparison with other countries including NUTS, OECD, FIPS, CIA World Factbook, ISO 3166-2 and the UN's Second Administrative Level Boundaries data set project (SALB).
