Sometimes a large area place has smaller area places within it. Examples include different medical buildings within a hospital campus or campgrounds within a national park. If the places are different colors, then a smaller place will appear to be "on top of" any larger area places where they overlap. If they are the same color, then there will be no way to distinguish the two areas. The primary names of all the area places will be visible.

Sometimes a large area place has smaller area places within it. Examples include different medical buildings within a hospital campus or separate malls within a large shopping complex. If both places are the same color, Waze will show all the labels but not the boundaries of the different places - it may be a better approach to use point places for the components of a larger area place unless it is essential that the subset place names be visible. If the places are different colors, then a smaller place will appear to cover any portions of any larger area place where the two overlap - this permits showing a ski resort area in the middle of a national forest, for example.

Sometimes a large Area Place has smaller eligible Area Places within it. Examples include urgent care facilities within a hospital campus or stadiums within a university. If an Area Place is mapped as a subset of another, then provided the categories render with different colors, the smaller area polygon will display within the larger polygon.

In the common case where the Places share the identical display color, however, Waze will show the name of the smaller Area Place but not its boundaries within the larger Area Place. Waze will show both names with the identical typeface and font size; drivers won't have any cues as to relative significance without reading the names. Further, to avoid overlapping text, Waze may omit a name altogether depending from moment to moment on name length, Area-Place size, and screen center, zoom, and orientation.

Because of this display behavior, the end result of overlapping Area Places may involve unintended artifacts. The name of a more important Area Place may be omitted to favor one less important, the display may crowd with many names all appearing equally important, or the names may render far enough from their true location to be less useful for orientation. To minimize such artifacts, exercise discretion when mapping Area Places as subsets of others. Guidance for some Place categories recommends using Point Places for subset locations, even if normally eligible for an Area Place. For other categories, particularly when the subset and encompassing Area Places are of the same category, it is not necessarily wrong to use a Point Place instead of a subset Area Place to optimize the end user's display experience; consult local leadership on the best approach.
