<p>I sent it in like 3 weeks ago too and haven't gotten any confirmation. I don't think we have an ID number yet so I don't know what they're talking about.</p>
<p>And what do you mean by certified mail? Do those get a confirmation or something? I just used the envolope Cornell provided.</p>
<p>i did not have an ID # when i sent in the deposit
but i used a register mail so that i could track it (delivered or not)
i think ID #s are assigned when they have processed your $400</p>
<p>I sent mine a long time ago, yet I did not get my NetID or anything. However, I did get an e-mail the other day giving me a heads up about the fact that I'm getting my dining and housing forms and such in April along with the regular decision students.</p>
