IAM JSON policy elements: Sid - AWS Identity and Access Management
Services or capabilities described in AWS documentation might vary by Region. To see the differences applicable to the AWS European Sovereign Cloud Region, see the AWS European Sovereign Cloud User Guide.

IAM JSON policy elements: Sid

You can provide a 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.

JSON
{
  "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.
