The problem comes in when: You don't have a driver's license (for whatever reason) You don't have a birth certificate (for whatever reason) You don't have a social security card (for whatever reason) Could be lost/stolen/etc.... But then suddenly proving your identity becomes a time consuming and possible costly affair. It becomes much harder if you can't trace backwards (I think my mom had to help my brother get his birth certificate when he needed one again). Yes, for the person with a car and who holds a job it is easy.... (and if they get stolen, still easy) note you can't legally work without a social security card JM
