Thanks everyone! I still haven't found the kids CRNs but we've only claimed Baby Bonuses for them, not CCB or CCR or parenting payments or anything. But I found my hubby's CRN and I got partway through the online reset thingy successfully til the website seemed to have a meltdown and said "service temporarily unavailable".
Sorry to argue but I have to disagree with a couple of the points raised by Russell.
He has mentioned being able to see the crn of a child if you have nominee access. A nominee is someone able to enquire and, in some cases, take action on a centrelink account on behalf of a customer. A young child would very rarely be a customer so they are linked to a parent/carer account and you are able to access through your own login. Given you can't be a nominee for a child you have nominee access to a file for them. Anything you would be able to view relating to a child in your care you would access through your own login (provides you have maximum access - level 3or4).
I'm not sure if it has been updated at this point but you may be able to see your child's crn if you claim CCB for them. I use the Express Plus Families app and can see my daughters crn even though I don't claim CCB, and honestly haven't checked through the standard login from a pc to see if it is available to me that way, so hopefully it has been. Unfortunately I can't confirm where to look on normal online services to confirm those details.
Given the question posed on the opening post was about how to get access to online services with a forgotten CAN I would suggest, as I did earlier, that the best way would be for someone to reset your password and give you a new temporary password. And given how infrequently you access your online services,ale a note of the details somewhere.
