Children can collect SSI if they are disabled or a dependent of a person who died. Many children collect SSI until they are 18 years of age because a parent passed away, and if they remain in school they can collect until 21 or 22 years of age.
Please see my post #64.

Our son died at age 19. He is on the SSDI. The SSDI is for anyone who had a SS number. Not sure why some don’t show up. My brother also died at age 38 and is on there. Neither one collected SS or SSI.
