In April, Amazon Web Services announced the availability of longer volume and snapshot IDs for EBS and Storage Gateway. Starting today, June 29, 2016, all newly created AWS accounts will use longer volume and snapshot IDs by default in all regions except China (Beijing) and AWS GovCloud (US). If you have not yet tested your systems for compatibility with longer volume and snapshot IDs, you still have the option to request the shorter ID format if necessary. For new AWS regions launching later in 2016, all accounts will default to longer EC2 and EBS IDs, with the option to opt out if needed. 

We strongly recommend testing your systems and opting into the longer ID format before December 2016. After you opt in, only new instances, reservations, volumes, or snapshots will receive longer IDs; existing resources will not be affected. Some AWS CLI and SDK versions are not compatible with longer IDs. From December, all new instances, reservations, volumes, and snapshots will be created with longer IDs. 

For instructions regarding how to opt in to longer IDs, visit the AWS Blog. More information about timelines, testing procedures, a full list of affected tools and compatible versions, and more can be found on the EC2 FAQ and the EC2 User Guide. If you have questions, please contact the AWS support team
