Iowa Admin. Code r. 761-540.6
If during the period the permit is valid any information required and presented in the application under subrule 540.4(1) changes, the transportation network company is to notify the motor vehicle division of the change in writing within 30 days after the change. Notification is to include the permit number and a description of the information that has changed and needs to be updated in the department's records. Submission of amended information is not a request for a new permit or for permit approval and does not extend the period the permit is valid. Upon determination that the information submitted is complete and correct, the department shall update its records and issue an amended permit, if the department determines it is necessary.
