<p>I submitted my common app/supplement online but had to send the school forms on paper (offline). I just realized my name is pretty common and wondered how they would distinguish my school forms as opposed to someone else's in the case that there's another applicant with the same name as mine.</p>
<p>i’d assume by ur mailing address mate. best advice i can think of. maybe someone else will know cause i’m curious too now, though my name isnt really common.</p>
<p>Birthday, plus ur common app ID which is on the bottom of the school forms</p>
<p>Name, birthday, current school, address, etc. </p>
<p>The common app ID isn’t necessarily on the bottom of the forms depending on how you access it which is just fine.</p>
