-- Definition --<br/>An address component which represents the name of a geographic area or locality that groups a number of addressable objects for addressing purposes, without being an administrative unit.<br/><br/>-- Description --<br/>NOTE 1 In some countries and regions an address area is a true subdivision of an administrative unit (most often a municipality), so that every address area is fully inside the municipality and so that every part of the municipality is within an address area. In other countries, the concept of address area names is less strict and based on local tradition or specific needs. <br/><br/>NOTE 2 In some situations an address area name is not required to obtain unambiguousness; instead the purpose is to make the complete address more informative and descriptive, adding a well known place name (e.g. of a village or community) to the address. This is particularly useful if the municipality or post code covers a large area. <br/><br/>EXAMPLE 1 In Sweden a "Kommundel" (en: Municipal sub division) is a type of address area names that ensures that street names are unique within the sub division. <br/><br/>EXAMPLE 2 In Spain an "Entidad de población" (en: population entity) has the same function. It is the general address area which depending on its characteristics can be classified as "Entidad Singular" (en: singular entity) or "Entidad Colectiva" (en: collective entity). Moreover, according to the population distribution, these areas can contain one or several "Núcleo de población" (en: population core) and/or "Población diseminada" (en: scattered population).<br/><br/>EXAMPLE 3 In Denmark "Supplerende bynavn" (en: Supplementary town name) is sometimes compulsory to ensure uniqueness of street names within the post code, sometimes it is just useful extra information, that makes the address more informative.<br/>
