When the department approves an application for personalized message license plates, the department shall notify the applicant and deliver the license plates and registration certificate to the applicant by United States mail or to the county treasurer of the county in which the motor vehicle or trailer is to be registered and the delivery of the plates and registration certificate shall be made through a secure process and system. Beginning on an implementation date designated by the director on or before January 1, 2022, if delivery of the plates and registration certificate is made by the department to the applicant, the department may charge a postage and handling fee in an amount not more than necessary to recover the cost of postage and handling for the specific items mailed to the registrant.

The county treasurer or the department shall issue such plates to the applicant, in lieu of regular license plates, when the applicant complies with the other provisions of law for registration of the motor vehicle or trailer.
