Youth payments are paid into parent accounts until the child turns 18 unless the parent signs the payment over to the child

the application is done online - the CRN for the child IS the one on the parent HCC or file, but, when signing up online, it creates a seperate CAN (customer access number) as the child file is linked to the parent file (not stand alone). it just means they have one number they are paid through (CRN) and one they use for self service (CAN) - many customers have two numbers.

i'm not sure the exact process for claiming though as i don't work in youth, but i'll assume it is similar to families

register for online services
menu on the left hand side gives you the option to make a claim (not sure of wording but i think it will be top option)
fill in claim as student
submit.

this will then be linked from CAN to CRN

the application will ask that parental income be provided - that one can be provided through the parents online services account i believe
