Oh, hey, i was wondering if it is possible to present other documents as proof?
Sure. In that case, just certain documents are accepted, and these should have child's name, date of birth or age, and a recent photograph, to be acceptable.
So, those would be helpful to get that SSN card, isn't?
That's correct. Be aware though that any document you present must be originals or copies certified by the agency that issued them. Of course, must be unexpired too.
