UBIGEO () is the coding system for geographical locations (Spanish: Código UbicacÃÂon Geográfica) in Peru used by the National Institute of Statistics and Informatics (Spanish: Instituto Nacional de EstadÃÂstica e Informática, INEI) to code the first-level administrative subdivision: regions (Spanish: regiones, singular: región), the second-level administrative subdivision: provinces (Spanish: provincias, singular: provincia) and the third-level administrative subdivision: districts (Spanish: distritos, singular: distrito). There are 1874 different ubigeos in Peru.
The coding system uses two-digit numbers for each level of subdivision. The first level starts numbering at <code>01</code> for the Amazonas Region and continues in alphabetical order up to <code>25</code> for the Ucayali Region. Additional regions will be added to the end of the list, starting with the first available number.
The second level starts with <code>0101</code> for the first province in the Amazonas region: Chachapoyas Province and continues up to <code>2504</code> for the last province Purús in the Ucayali Region. The provinces are numbered per region with the first province always being the one in which the regions capital is located. The remaining provinces are coded in alphabetical order. Additional provinces will be added per region to the end of the list, starting with the first available province number.
The third level; starts with <code>010101</code> for the first district in the first province in the Amazonas region: Chachapoyas District and continues up to <code>250401</code> for the last district in the last province of the Ucayali region: Purús District. The districts are numbered per province with the first district always being the one in which the province's capital is located. The remaining districts are coded in alphabetical order. Additional districts will be added per province to the end of the list, starting with the first available district number.
