[ aws . ec2 ]



Describes the longer ID format settings for all resource types in a specific Region. This request is useful for performing a quick audit to determine whether a specific Region is fully opted in for longer IDs (17-character IDs).

This request only returns information about resource types that support longer IDs.

The following resource types support longer IDs: bundle | conversion-task | customer-gateway | dhcp-options | elastic-ip-allocation | elastic-ip-association | export-task | flow-log | image | import-task | instance | internet-gateway | network-acl | network-acl-association | network-interface | network-interface-attachment | prefix-list | reservation | route-table | route-table-association | security-group | snapshot | subnet | subnet-cidr-block-association | volume | vpc | vpc-cidr-block-association | vpc-endpoint | vpc-peering-connection | vpn-connection | vpn-gateway .

[--dry-run | --no-dry-run]
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]


--dry-run | --no-dry-run (boolean)

Checks whether you have the required permissions for the action, without actually making the request, and provides an error response. If you have the required permissions, the error response is DryRunOperation . Otherwise, it is UnauthorizedOperation .

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

To describe the longer ID format settings for all resource types in a Region

The following describe-aggregate-id-format example describes the overall long ID format status for the current Region. The Deadline value indicates that the deadlines for these resources to permanently switch from the short ID format to the long ID format expired. The UseLongIdsAggregated value indicates that all IAM users and IAM roles are configured to use long ID format for all resource types.

aws ec2 describe-aggregate-id-format


    "UseLongIdsAggregated": true,
    "Statuses": [
            "Deadline": "2018-08-13T02:00:00.000Z",
            "Resource": "network-interface-attachment",
            "UseLongIds": true
            "Deadline": "2016-12-13T02:00:00.000Z",
            "Resource": "instance",
            "UseLongIds": true

            "Resource": "elastic-ip-association",
            "UseLongIds": true


UseLongIdsAggregated -> (boolean)

Indicates whether all resource types in the Region are configured to use longer IDs. This value is only true if all users are configured to use longer IDs for all resources types in the Region.

Statuses -> (list)

Information about each resource’s ID format.


Describes the ID format for a resource.

Deadline -> (timestamp)

The date in UTC at which you are permanently switched over to using longer IDs. If a deadline is not yet available for this resource type, this field is not returned.

Resource -> (string)

The type of resource.

UseLongIds -> (boolean)

Indicates whether longer IDs (17-character IDs) are enabled for the resource.
