When purchasing training courses through Xvoucher, you do not need an Xvoucher account.
All customers should search and register for training sessions via aws.training.
AWS certification exam vouchers are sold separately from AWS training and can be purchased by visiting the Xvoucher Store.
If you have issues or questions about your training please review your transcript on aws.training or visit the AWS T&C Support page: https://www.aws.training/support
