# Create Attribute Collection

Before you can create an attrbute collection on an identity, you must have an attribute collection authority to associate it with. 


## Creating An Attribute Collection Authority {#creating-an-attribute-collection-authority}


Choose a name that is descriptive and meaningful, which can be easily identified as belonging to a specific internal team responsible for the data in the collections within it. 

Once you have chosen a name, contact Cirrus Customer Success. At this time, attribute collection authorities can only be created by Cirrus Engineering.

After your authority has been created, you can use API permissions that were granted access to that authority to [create attribute collections & values](/identities-api.md#operation-attributecollections-create-cirrusuid-post) for any identity in Managed Identities.

> **Heads Up!**

> Avoid creating attribute collections with duplicative attribute names. This can cause confusion and conflicts.
