I've been trying to ring Centrelink all day but just get an engaged signal. I need to know my child's CRN for his childcare enrolment form. Does anyone know if phoning Centrelink is the only way to get this? Going to the Centrelink office is out, unfortunately, as I am recently out of hospital and not up to standing in line. I am registered for online services but can't find the answer as I find the site confusing. Thanks all.
