AWS generated cost allocation tags - AWS Billing

AWS generated cost allocation tags

The AWS-generated tag createdBy is a tag that AWS defines and applies to supported AWS resources for cost allocation purposes. To use the AWS-generated tag, a management account owner must activate it in the Billing and Cost Management console. When a management account owner activates the tag, the tag is also activated for all member accounts. After the tag is activated, AWS starts applying the tag to resources that are created after the AWS-generated tag is activated. The AWS-generated tag is available only in the Billing and Cost Management console and reports, and doesn't appear anywhere else in the AWS console, including the AWS Tag Editor. The createdBy tag does not count towards your tags per resource quota.

The aws:createdBy tags are populated only in the following AWS Regions:

  • ap-northeast-1

  • ap-northeast-2

  • ap-south-1

  • ap-southeast-1

  • ap-southeast-2

  • cn-north-1

  • eu-central-1

  • eu-west-1

  • sa-east-1

  • us-east-1

  • us-east-2

  • us-gov-west-1

  • us-west-1

  • us-west-2

Resources created outside of these AWS Regions will not have this tag auto-populated.

The createdBy tag uses the following key-value definition:

key = aws:createdBy
value = account-type:account-ID or access-key:user-name or role session name

Not all values include all of the value parameters. For example, the value for a AWS-generated tag for a root account doesn't always have a user name.

Valid values for the account-type are Root, IAMUser, AssumedRole, and FederatedUser.

If the tag has an account ID, the account-id tracks the account number of the root account or federated user who created the resource. If the tag has an access key, then the access-key tracks the IAM access key used and, if applicable, the session role name.

The user-name is the user name, if one is available.

Here are some examples of tag values:

Root:1234567890 Root: 111122223333 :exampleUser IAMUser: AIDACKCEVSQ6C2EXAMPLE :exampleUser AssumedRole: AKIAIOSFODNN7EXAMPLE :exampleRole FederatedUser:1234567890:exampleUser

For more information about IAM users, roles, and federation, see the IAM User Guide.

AWS generated cost allocation tags are applied on a best-effort basis. Issues with services that AWS-generated tag depends on, such as CloudTrail, can cause a gap in tagging.

The createdBy tag is applied only to the following services and resources after the following events.

AWS Marketplace vendor-provided tags

Certain AWS Marketplace vendors can create tags and associate them with your software usage. These tags will have the prefix aws:marketplace:isv:. To use the tags, a management account owner must activate the tag in the Billing and Cost Management console. When a management account owner activates the tag, the tag is also activated for all member accounts. Similar to aws:createdBy tags, these tags appear only in the Billing and Cost Management console and they don't count towards your tags per resource quota. You can find the tag keys that apply to the product on the AWS Marketplace product pages.
