Single-domain commercial authorization applies to top-level domains, such as the authorization for publiccms.com, and can also be used under its subdomains.

The authorized entity is the website owner. Entities with single-domain commercial authorization or unlimited-domain commercial authorization can grant their authorization to subordinate branches without legal person status, such as branch offices or sub-departments, but do not have the right to grant their authorization to subsidiaries or other entities.
