How Linkage Happens

1. If you create an AWS account with email address xyz123@cornell.edu, and there is no existing Amazon.com account for xyz123@cornell.edu then functionally, an Amazon.com account is created for xyz123@cornell.edu and those two accounts (AWS and Amazon.com) are linked forever.
2. If you create an AWS account with email address xyz123@cornell.edu, and there already is an existing Amazon.com account for xyz123@cornell.edu, then ????

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 remain active.
• If the AWS account is closed, the Amazon.com account remains active.
