Amazon Web Services (AWS), Closing an Account
When you no longer need your AWS account, you can send a request to aws-support@illinois.edu. Please include the AWS account ID (found in the drop down menu at the top right of your AWS web console).
The account enters a post-closure period for 90 days, in which you can request it be reopened and any services that were running prior to the account closure will resume. Once these 90 days are up, the account is permanently closed and can not be reopened.
You remain responsible for all outstanding fees and charges for the services consumed before account closure. You will receive an AWS bill the following month after closing your account. For example, if you closed your account on January 15, you will receive a bill in February for usage incurred from January 1 through January 15.
