# Placekey Types

Additional Placekey types can be returned with the optional “fields” parameter. See the [Example Queries](/documentation/placekey-api/example-queries.md) section of this documentation for details on how to return these additional Placekey types.

The additional Placekey types are `address_placekey` and `building_placekey`.

These provide more granular information about a place, address, and building. For example, let's consider a single-family home, apartment, and a POI with a suite number. For the single-family home all three Placekeys (`placekey`, `address_placekey`, and `building_placekey`) would be the same. The apartment would have the same Placekey and `address_placekey` but a different `building_placekey`. Finally, for the POI with a suite number, all three Placekey types would be different.
