Hello ,

Thank you for posting your question on the AWS Repost, my name is Rochak and it will be a pleasure assisting you with this today.

I understand you are trying to launch ec2 gpu instance in us-east-1 as well as you have tried launching g4ad.xlarge, and g5g.2xlarge instances and received the error provided.

As the error mentioned, it usually happens when your AWS account may be in the process of verified for launching GPU instance in us-east-1. Please kindly note that this is a security measure put in place to prevent the abuse of GPU instances. You can also try launching GPU instances in a different region where your account is already verified.

I also understand you have emailed aws-verfication@amazon.com which is the next step. If you haven’t still received a response, I recommend you to open a support case with our AWS Support team. AWS support includes various tier that you can select from depending on your business needs. The support team should be able to provide you with more information about the status of your account verification and help you resolve the issue. [1]

I hope this helps. If you need further info, let me know in the comments; otherwise I'd appreciate if you mark my answer as "accepted".

Kind regards, Rochak from AWS
