* ''Postal code''. Polygon of a [[postal code|postal area]]: a [[Código de Endereçamento Postal|CEP]] code (e.g. '''<code>70040</code>''' represents a Brazilian's central area for postal distribution).
The ISO 19112:2019 standard<ref>"ISO 19112:2019 — Geographic information — Spatial referencing by geographic identifiers", "Section 3.1.2 — Geographic identifier", https://www.iso.org/standard/70742.html</ref> (section 3.1.2) adopted the term "geographic identifier" instead ''geocode'', to encompass long labels: ''spatial reference in the form of a label or code that identifies a ___location''. For example, for ISO, the country name “People's Republic of China” is a label. Some authors, such as the United States Census Bureau,<ref>"Understanding Geographic Identifiers (GEOIDs)", https://www.census.gov/programs-surveys/geography/guidance/geo-identifiers.html</ref>
Geocodes are mainly used (in general as an [[Primitive data type|atomic data type]]) for [[labelling]], [[data integrity]], [[geotagging]] and [[Spatial database#Spatial index|spatial indexing]].
