# PutPublicAccessBlock
<a name="API_control_PutPublicAccessBlock"></a>

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

Creates or modifies the `PublicAccessBlock` configuration for an AWS account. This operation may be restricted when the account is managed by organization-level Block Public Access policies. You might get an Access Denied (403) error when the account is managed by organization-level Block Public Access policies. Organization-level policies override account-level settings, preventing direct account-level modifications. For this operation, users must have the `s3:PutAccountPublicAccessBlock` permission. For more information, see [ Using Amazon S3 block public access](https://docs.aws.amazon.com/AmazonS3/latest/dev/access-control-block-public-access.html).
