# What are customer properties?

> Store attributes like name, location, and custom data on customer profiles for segmentation.

Customer properties are attributes that are attached as data to a user. A customer can have **multiple properties** which are located on their profile.

You often get this data when a customer signs up to your site, fills out a survey or passes an order. These properties are key in Vero and let you segment your customer base with granularity.

Vero has reserved some properties:
