Amazon S3 now supports up to 1 million buckets per AWS account

Amazon S3 has increased the default bucket quota from 100 to 10,000 per AWS account. Additionally, any customer can request a quota increase up to 1 million buckets. As a result, customers can create new buckets for individual datasets that they store in S3 to more easily take advantage of capabilities such as default encryption, security policies, S3 Replication, and more to remove barriers to scaling and optimize their S3 storage architecture.

Amazon S3’s new default bucket quota of 10,000 buckets is now applied to all AWS accounts and requires no action by customers. To increase your bucket quota from 10,000 to up to 1 million buckets, simply request a quota increase via Service Quotas. You can create your first 2,000 buckets at no cost. Above 2,000 buckets, you are charged a small monthly fee.

The increased default general purpose bucket limit per account now applies to all AWS Regions. To learn more about general purpose bucket quotas, visit the S3 User Guide.
