# Unique Id

This node generates a unique ID, something that is very useful when storing data in a backend like Noodl Cloud Services.

<div className="ndl-image-with-background l">

![](/nodes/utilities/unique-id/unique-id.png)

</div>

Generating a unique ID for every entity in the database means that it can easily be retrieved and referenced, no matter what the content is.
