# Lists

> Use Lists to identify inquiries that match predefined values such as IP addresses or ID numbers.

A list helps you automatically identify inquiries that match a set of predefined characteristics. For example, you might want to decline all inquiries that are created from a known set of suspicious IP addresses, or that are associated with government ID numbers from known fraudsters. Alternatively, you may want to approve all inquiries associated with a set of vetted email addresses.

To automatically take action on a list match, you can set up a Persona [workflow](/workflows) to automatically approve or flag each inquiry that matches a particular list.

A **list** is a container of values, and each value stored in a list is called a **list item**. The type of the list determines what kind of values its list items can store.

Many types of characteristics can be put onto a list, including:

* Browser fingerprint
* Device fingerprint
* Country
* Email address
* Face (please [contact the customer support engineering team](https://app.withpersona.com/dashboard/contact-us) to learn more)
* Geolocation
* Government ID number
* Inquiry field
* IP address
* Name
* Phone number
* Selfie background
* String
