ListAliases - AWS Key Management Service


Gets a list of aliases in the caller's AWS account and region. For more information about aliases, see CreateAlias.

By default, the ListAliases operation returns all aliases in the account and region. To get only the aliases associated with a particular KMS key, use the KeyId parameter.

The ListAliases response can include aliases that you created and associated with your customer managed keys, and aliases that AWS created and associated with AWS managed keys in your account. You can recognize AWS aliases because their names have the format aws/<service-name>, such as aws/dynamodb.

The response might also include aliases that have no TargetKeyId field. These are predefined aliases that AWS has created but has not yet associated with a KMS key. Aliases that AWS creates in your account, including predefined aliases, do not count against your AWS KMS aliases quota.

Cross-account use: No. ListAliases does not return aliases in other AWS accounts.

Required permissions: kms:ListAliases (IAM policy)

For details, see Controlling access to aliases in the AWS Key Management Service Developer Guide.

Eventual consistency: The AWS KMS API follows an eventual consistency model. For more information, see AWS KMS eventual consistency.

Request Syntax

{ "KeyId": "string", "Limit": number, "Marker": "string" }

Request Parameters

For information about the parameters that are common to all actions, see Common Parameters.

The request accepts the following data in JSON format.


In the following list, the required parameters are described first.


Lists only aliases that are associated with the specified KMS key. Enter a KMS key in your AWS account.

This parameter is optional. If you omit it, ListAliases returns all aliases in the account and Region.

Specify the key ID or key ARN of the KMS key.

For example:

  • Key ID: 1234abcd-12ab-34cd-56ef-1234567890ab

  • Key ARN: arn:aws:kms:us-east-2:111122223333:key/1234abcd-12ab-34cd-56ef-1234567890ab

To get the key ID and key ARN for a KMS key, use ListKeys or DescribeKey.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 2048.

Required: No


Use this parameter to specify the maximum number of items to return. When this value is present, AWS KMS does not return more than the specified number of items, but it might return fewer.

This value is optional. If you include a value, it must be between 1 and 100, inclusive. If you do not include a value, it defaults to 50.

Type: Integer

Valid Range: Minimum value of 1. Maximum value of 100.

Required: No


Use this parameter in a subsequent request after you receive a response with truncated results. Set it to the value of NextMarker from the truncated response you just received.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 1024.

Pattern: [\u0020-\u00FF]*

Required: No

Response Syntax

{ "Aliases": [ { "AliasArn": "string", "AliasName": "string", "CreationDate": number, "LastUpdatedDate": number, "TargetKeyId": "string" } ], "NextMarker": "string", "Truncated": boolean }

Response Elements

If the action is successful, the service sends back an HTTP 200 response.

The following data is returned in JSON format by the service.


A list of aliases.

Type: Array of AliasListEntry objects


When Truncated is true, this element is present and contains the value to use for the Marker parameter in a subsequent request.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 1024.

Pattern: [\u0020-\u00FF]*


A flag that indicates whether there are more items in the list. When this value is true, the list in this response is truncated. To get more items, pass the value of the NextMarker element in this response to the Marker parameter in a subsequent request.

Type: Boolean


For information about the errors that are common to all actions, see Common Errors.
