-Once you enable user attributes for cost allocation, you can map usage to internal organizational structures. You can use user attributes to see which teams, departments, or cost centers are consuming AWS services and at what rate, enabling data-driven decisions about resource allocation, budget planning, and optimization opportunities.

+After completing the setup, user attributes will appear in your Cost and Usage Report 2.0 (CUR 2.0) alongside other cost allocation tags. When viewing cost data in CUR 2.0, tags from different sources (resources, user attributes, accounts, and cost categories) are distinguished by prefixes to prevent conflicts when the same tag key is used across multiple contexts. For detailed information about how tag prefixes work and examples of overlapping tag keys, see the [CUR 2.0 Tags Column documentation](https://docs.aws.amazon.com/cur/latest/userguide/table-dictionary-cur2-tag-columns.html).
