(1) A number was assigned in error to a person who was not subject to Section 34507.5 of the Vehicle Code at the time the number was assigned.

(2) A second or subsequent number was assigned to the same person in error. In this circumstance, any carrier or terminal information associated with a superfluous CA number will be transferred to the person's correct CA number.

(3) The department has determined that the person no longer exists as a legal entity or has ceased to be subject to Section 34507.5 of the Vehicle Code, and sufficient time has passed that the department is unlikely to need to refer to the record associated with that CA number, and legal action against that person, as a motor carrier or a motor carrier of property, is not pending or contemplated by the department, and is not known to the department to be pending or contemplated by the Department of Motor Vehicles, the Public Utilities Commission, or the Federal Motor Carrier Safety Administration.

(4) The department will coordinate with the Department of Motor Vehicles to ensure that deletion of a CA number does not cause the inadvertent invalidation of a motor carrier of property permit, and if the carrier possesses such a permit, to arrange with the Department of Motor Vehicles for corresponding correction of relevant information associated with the permit in that agency's records, such as correction of the CA number associated with it.
