It is the duty of every licensee to notify the commissioner whenever any change in his Chicago address, telephone number, electronic mail (e-mail), or contact information is made. The licensee must notify the commissioner of such change within four business days of the change. It is proper notice for the commissioner to send notices to the licensee's last Chicago address recorded in the office of the commissioner.
