There are a few ways that you can find out what policies are applied to your account. The most common way is to check the Account Policies section in the AWS Management Console. This section will list all of the policies that have been applied to your account. Another way to find out what policies are applied is by using the AWS Command Line Interface (CLI). You can use the describe-account-attributes command to get a list of all the account attributes, including the ones that contain information about which policies are applied. Finally, you can also contact AWS Support and ask them to provide you with a list of all the policies that are applied to your account.
