# Inventory return locations

Inventory return locations build a hierarchy of [stock locations](https://docs.commercelayer.io/core-api-reference/stock_locations) within an [inventory model](https://docs.commercelayer.io/core-api-reference/inventory_models), determining the available options for [returns](https://docs.commercelayer.io/core-api-reference/returns). In case an SKU is available in more stock locations, it gets returned to those with the highest priority.
