To find untagged resources in your account, use Amazon Resource Explorer with a query that uses `tag:none`. Resource Explorer provides comprehensive search capabilities to identify resources that lack proper tagging or have inconsistent tag values across your organization. 

For detailed instructions on using Resource Explorer to find untagged and mistagged resources, see [Search for untagged resources](https://docs.amazonaws.cn/resource-explorer/latest/userguide/using-search-query-examples.html#example-1) in the *Amazon Resource Explorer User Guide*.
