Each Amazon account has a name and e-mail address associated with it, as well as a 12-digit account identifier (ID). When you share an AMI with another Amazon account, you may need to provide this number. Below is one way you can find your account number.
- Log in to the AWS Management Console.
- At the top of the page, click the link that is your account name.
- Click My Account.
- Your 12-digit account ID is listed under Account Settings.
