unregisterable

Impossible to catalog

Unable to be registered or enrolled in an official system.

The term appears in bureaucratic and legal contexts where something fails to meet requirements for formal recognition: The vehicle was unregisterable due to its modified frame.

Also applies to domains, trademarks, or accounts that cannot be claimed: That username is unregisterable—it contains prohibited characters.
