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.
