Yes, if a registered domain name is released by the registrar due to expiration and not renewed within the grace period, the registration information will typically be canceled. The domain name will enter a redemption period (if available), and after that, it becomes available for public registration again. During this process, the original registrant's information may no longer be associated with the domain.
For example, if a domain like "example.com" expires and the owner fails to renew it within the grace period (usually 30-45 days), the registrar may release it. Once released, the domain could be registered by someone else, and the original owner's contact details would no longer be linked to it.
