General purpose bucket quotas, limitations, and restrictions

An Amazon S3 general purpose bucket is owned by the Amazon Web Services account that created it. Bucket ownership is not transferable to another account.

Bucket quotas

By default, you can create up to 10,000 general purpose buckets per Amazon Web Services account. To request a quota increase for general purpose buckets, visit the Service Quotas console.

Important

We strongly recommend using only paginated ListBuckets requests. Unpaginated ListBuckets requests are only supported for Amazon Web Services accounts set to the default general purpose bucket quota of 10,000. If you have an approved general purpose bucket quota above 10,000, you must send paginated ListBuckets requests to list your account’s buckets. All unpaginated ListBuckets requests will be rejected for Amazon Web Services accounts with a general purpose bucket quota greater than 10,000.

Note

You must use the following Amazon Web Services Regions to view your quota, bucket utilization, or request an increase for your general purpose buckets in your Amazon Web Services account.

  • General purpose bucket quotas for commercial Regions can only be viewed and managed from US East (N. Virginia).

  • General purpose bucket quotas for China Regions can only be viewed and managed from China (Beijing) Region.

  • General purpose bucket quotas for Amazon GovCloud (US) can only be viewed and managed from Amazon GovCloud (US-West).

For information about service quotas, see Amazon service quotas in the Amazon Web Services General Reference.

Objects and bucket limitations

There is no max bucket size or limit to the number of objects that you can store in a bucket. You can store all of your objects in a single bucket, or you can organize them across several buckets. However, you can't create a bucket from within another bucket.

Bucket naming rules

When you create a bucket, you choose its name and the Amazon Web Services Region to create it in. After you create a bucket, you can't change its name or Region. For more information about bucket naming, see General purpose bucket naming rules.
