By default CloudPanel only allows you to create a unique domain per company. If you want the ability to assign the same domain name to multiple customers you can modify this value.

Default Value (0):

• Duplicate domains are not allowed. A domain can only belong to a single company

Allow (1):

• Allows a domain to belong to multiple companies (no limit).
• Any changes made to a domain is changed for ALL companies. It is best practice to restrict company administrators from modifying domain values when using duplicate domains.
