The admin_level key describes the administrative level of an object within a government hierarchy. A lower level means higher in the hierarchy. This tag is used for the borders of territorial political entities (e.g. country, state, municipality) together with boundary=administrative. Due to cultural and political differences, admin levels of different countries only correspond approximately to each other.


admin_level=1 to 10 has been introduced in order that different borders can be rendered consistently among countries (doing this based on border_type would require knowledge of their hierarchy in each country). This tag can be regarded as a property, i.e. it isn't a feature by its own but is rather used to describe a certain aspect of a feature.


admin_level=* is used together with the following keys:

In addition to the direct usage of this tag with the keys above, the numeric values used by admin_level=* are also used for tags:
