Add, edit, or delete custom
properties in SharePoint Server 2013 user profiles
The Manage Profile Service page of a User Profile service application in SharePoint Server 2013 is a central location for managing available user profile properties and creating new properties. For more information, see Overview of the User Profile service application in SharePoint Server 2013.
You can supplement default user profile properties with additional properties to track key information that is not otherwise available. Key business needs might encourage you to create new properties that associate users with important business processes. For example, a sales department can create a specific sales role property to share with a particular audience or audiences. Custom user profile properties can be edited to better suit business needs or they can be deleted when no longer needed.
The Manage Profile Service page cannot be accessed until an instance of a User Profile service application exists. You can use the SharePoint Central Administration website to create and manage User Profile service applications and other service applications for non-hosted environments. (For hosted environments, you do this on the Tenant Administrator page.) You can delegate administration of a User Profile service application to someone who does not have permissions to manage other services or settings contained in Central Administration. For more information, see Delegate administration of User Profile service applications in SharePoint Server 2013
