Common App--two different ID numbers

<p>OK, after I sent the common app to the EA college, I revised it, and I am sending it to the other colleges. But I gave recommendation forms to teachers long time ago, so it already sent to colleges with the original ID number. </p>

<p>Should I email colleges and let them know that I have a different ID number on teacher recommendation letters? I am sure it is answered somewher, but I can not find the thread, so please help me once more.</p>
