# DeletePublicAccessBlock
<a name="API_DeletePublicAccessBlock"></a>

**Note**  
This operation is not supported for directory buckets.

Removes the `PublicAccessBlock` configuration for an Amazon S3 bucket. This operation removes the bucket-level configuration only. The effective public access behavior will still be governed by account-level settings (which may inherit from organization-level policies). To use this operation, you must have the `s3:PutBucketPublicAccessBlock` permission. For more information about permissions, see [Permissions Related to Bucket Subresource Operations](https://docs.amazonaws.cn/AmazonS3/latest/userguide/using-with-s3-actions.html#using-with-s3-actions-related-to-bucket-subresources) and [Managing Access Permissions to Your Amazon S3 Resources](https://docs.amazonaws.cn/AmazonS3/latest/userguide/s3-access-control.html).
