<p>I sent all my application documents without a UT EID written on it. It can cause lots of trouble though. My online full name was different than what I put on the mailed documents. So after the application process I had two UT EIDs sent to me which was then merged with some difficulty. If you don’t have a UT EID and don’t plan to get one yet, make sure everything on your documents correspond exactly to what you gave online.</p>
