Letter of Recommendation.

<p>Hello all,
first of all, forgive me if this is in the wrong place, i couldn't find another category it would fit into.</p>

<p>On to my actual question: One of my recommenders sent his letter through regular mail, i wasn't too worried about this but the thought has occurred to me that i'm not sure that my colleges will be able to identify it. should my common app ID have been put on the letter? i have no idea why i haven't thought of this before now, what can i do to fix this?
Thanks Everyone.
(please forgive any errors or typos, it's fairly late at night )</p>

<p>oh shit I DID THE SAME THING</p>

<p>oh god time to contact every single college with mailed recommendations to make sure they got the rec</p>
