Tagging AWS Organizations resources - AWS Organizations

Tagging AWS Organizations resources

A tag is a custom attribute label that you add to an AWS resource to make it easier to identify, organize, and search for resources. Each tag has two parts:

  • A tag key (for example, CostCenter, Environment, or Project). Tag keys can be up to 128 characters in length and are case sensitive.

  • A tag value (for example, 111122223333 or Production). Tag values can be up to 256 characters in length, and like tag keys, are case sensitive. You can set the value of a tag to an empty string, but you can't set the value of a tag to null. Omitting the tag value is the same as using an empty string.

For more information about what characters are allowed in a tag key or value, see the Tags parameter of the Tag API in the Resource Groups Tagging API Reference.

You can use tags to categorize resources by purpose, owner, environment, or other criteria. For more information, see Best Practices for Tagging AWS Resources.

Tip

Use tag policies to help standardize your implementation of tags across the resources in your organization's accounts.
