Management account owners can activate the Amazon-generated tags in the Billing and Cost Management console. When a management account owner activates the tag, it's also activated for all member accounts. This tag is visible only in the Billing and Cost Management console and reports.

You can activate the `createdBy` tag in the Billing and Cost Management console. This tag is available in specific Amazon Web Services Regions. For more information, see [Using Amazon-generated tags](aws-tags.md).<a name="activate-built-in-tag"></a>
