# Zone types
A **zone type** refers to a category that groups together multiple zones sharing common characteristics, such as model, brand, dimensions, inspection frequency, or operating cost. Each zone can be assigned to a fully customizable type.
In the **“Types”** section of the **“Storage zones”** module, you can view, edit, or delete these zone types.
Using zone types enables you to:
* Categorize zones based on their purpose (e.g., Truck XXX, Depot X, etc.).
* Standardize zone management by applying shared parameters across multiple locations.
* Automate specific rules, such as control periodicity.
