Introducing account regional namespaces for Amazon S3 general purpose buckets

This article announces account regional namespaces for Amazon S3 general purpose buckets, enabling simplified bucket creation and management.

• Create general purpose buckets with account-specific suffixes ensuring name availability
• Bucket names include account ID, region, and "-an" suffix (e.g., mybucket-123456789012-us-east-1-an)
• Other accounts cannot use your account's suffix, preventing naming conflicts
• Enforce namespace usage via IAM policies and AWS Organizations service control policies
• Supports all general purpose bucket features with no additional cost
• Available in 37 AWS Regions including China and GovCloud
• Create via S3 console, AWS CLI, SDKs, or CloudFormation templates

This feature simplifies S3 bucket management by guaranteeing name availability within account-regional namespaces while maintaining security controls.
