**To describe the ID format for your resources**

This example describes the ID format for all resource types that support longer IDs. The output indicates that the bundle, conversion-task, customer-gateway, dhcp-options, elastic-ip-allocation, elastic-ip-association, export-task, flow-log, image, import-task, internet-gateway, network-acl, network-acl-association, network-interface, network-interface-attachment, prefix-list, route-table, route-table-association, security-group, subnet, subnet-cidr-block-association, vpc, vpc-cidr-block-association, vpc-endpoint, vpc-peering-connection, vpn-connection, and vpn-gateway resource types can be enabled or disabled for longer IDs. The ``Deadline`` for the reservation, instance, volume, and snapshot resource types indicates that the deadline for those resources expired at 00:00 UTC on December 15, 2016. It also shows that all of the resource types, except vpc, subnet, and security-group, are configured to use longer IDs.
