Political/electoral, rather than administrative, boundaries are created as boundary type relations tagged boundary=political. Examples include electoral wards, electoral districts and parliamentary constituencies.
Way tags
Ways for political (rather than administrative) boundaries do not need any special tags. If the way has no other tags, then boundary=political (and political_division=*) can be added, but it isn't really needed if the relation is correctly tagged.

Relation members
| Element | Role | Occurrence | Discussion |
|---|---|---|---|
| outer | ! 1+ | The multiple ways that form the closed border. | |
| inner | ? 0+ | Enclaves of this border – the multiple ways that form the closed inner borders. | |
| ✗ 0 | Deprecated. It's often difficult to discriminate exclaves to designate one as the main "outer" area: it could be the largest one, or the area that contains the official centre, but some boundaries have several centres, or this centre is not always in the largest area. In addition there may exist exclaves that are part of the outer boundary, but which are enclaved in another boundary enclaved in the outermost area. For this reason, only outer and inner are useful geometrically. | ||

| admin_centre | ? 0–1 | Node representing the administrative centre, usually a town, city or village (depending of the boundary level, see place=*) | |
| label | ? 0–1 | Node representing where to draw the label. |
Rendering
When using search or the query features tool, the web front end lists objects with boundary=political with prefix "Electoral boundary" (translated in the language of the website visitor). However, political boundaries are not rendered on the standard tile layer.
