IAM JSON policy elements: Sid

You can provide Sid (statement ID) as an optional identifier for the policy statement. You can assign a Sid value to each statement in a statement array. You can use the Sid value as a description for the policy statement. In services that let you specify an ID element, such as SQS and SNS, the Sid value is just a sub-ID of the policy document ID. In IAM, the Sid value must be unique within a JSON policy.

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Sid": "ExampleStatementID",
      "Effect": "Allow",
      "Action": "s3:ListAllMyBuckets",
      "Resource": "*"
    }
  ]
}

The Sid element supports ASCII uppercase letters (A-Z), lowercase letters (a-z), and numbers (0-9).

IAM does not expose the Sid in the IAM API. You can't retrieve a particular statement based on this ID.

Note

Some AWS services (for example, Amazon SQS or Amazon SNS) might require this element and have uniqueness requirements for it. For service-specific information about writing policies, refer to the documentation for the service you work with.
