Maybe not directly give it to them but it (the SS No.) is required for almost everything, and put on almost everything. Therefore it would not be impossible for a kid to know it. In fact the other day I got real upset because I called some insurance companies (Allstate, Farmers) to get estimates on homeowners insurance and they wanted my SS No. I told them I do not give out my SS No. They told me they were not able to give me an estimate without it. Their computer program would not allow them access without it. They needed it to do a consumer report. I said you don't want my business then, do you? Their response was sorry, but that is the way it is.
