If you have an Amazon.com shopping account with email address xyz123@cornell.edu, and create an AWS account with that same email address (xyz123@cornell.edu), the Amazon.com account and the AWS account become linked (forever).

Ramifications

In this situation:

• If you were to change the root email address for the AWS account, it would also change the email address for the Amazon.com account.
• If you were to change the email address for the Amazon.com account, it would also change the root email address for the AWS account.
• AWS/Amazon cannot manually unlink or decouple these accounts.
• If the Amazon.com account is closed, the AWS account will get closed.
