<p>I realized that on the common app, I put down a different email address than the one I wrote on my supplements. Does this matter? Will the colleges know that I'm one person?</p>
<p>Don’t over-think this!</p>
<p>Colleges will know that you’re the same person. They have a lot more information to match your things to your file. However, there’s another thing you should consider, however. Colleges will use one email address to contact you; most likely, they’ll open your file using the email address on the part of the application that reached them first. You should probably send them a fax/email/call them to let them know which email address they should use. Nevertheless, you’ll probably be fine anyway.</p>
