Create an AWS Account

In AWS Organizations select the Add an AWS Account button. Complete the form as follows:

Value	Description
AWS Account Name	Name the account for example, staging
Email address of the account's owner	The account's owner. This email address cannot already be associated with another AWS account because it becomes the user name credential for the root user of the account.
IAM role name	Specify the name to assign to the IAM role that is automatically created in the new account. This role grants the organization's management account permission to access the newly created member account. If you don't specify a name, AWS Organizations gives the role a default name of OrganizationAccountAccessRole. We recommend that you use the default name across all of your accounts for consistency.

Now that the account exists and has an IAM role that grants administrator access to users in the management account, you can access the account by following the steps in Accessing and administering the member accounts in your organization.
