Programmatically manage enabled and disabled opt-in AWS Regions on AWS accounts

Today, we are making it easier for customers to view and manage enabled and disabled opt-in AWS Regions on their AWS accounts using the AWS Command Line Interface (CLI) and AWS Software Development Kit (SDK). We previously released the [Accounts SDK](/about-aws/whats-new/2021/10/programmatically-manage-alternate-contacts-aws-accounts/) that enables customers to programmatically manage both primary and alternate contact information for their accounts. Starting today, customers can use the same SDK to additionally enable and disable opt-in AWS Regions, saving them the time and effort of doing it through the AWS Management Console. Additionally, for customers using [AWS Organizations](/organizations/), Organization administrators can now centrally manage the status of opt-in AWS Regions for all member accounts using the management account. The ability to enable and disable opt-in AWS Regions on AWS accounts is available at no additional charge in all commercial AWS Regions. To learn more about account management, see [the documentation](https://docs.aws.amazon.com/accounts/latest/reference/manage-acct-regions.html).
