<p>I submitted Part I of the application but never got a USC ID # through the email they sent me. Where can I get it?</p>
<p>It’ll change like 12 times throughout the process and then finally be one you’ve never seen before if it’s anything like my process.</p>
<p>Look at anything the school has mailed you. If there’s a sticker address label, it should be on there. Not all mail from USC has it, but some of it does. The farther you get in the application process, the more mail (and stickers) (and numbers) you’ll get.</p>
