<p>on the common app and the supplement there is a blank to input your social security number. i was too lazy to dig it up, and so i never put it in. considering how it's optional (as in you can submit your supplement without it), do you think this will disadvantage me? i'm only asking because the university of california just sent me an email asking for my SSN despite the fact that online it doesn't make it a requirement.</p>
<p>so does anyone know if my SSN needed? and if so, how could i send it to uchicago?</p>
