Hi Santhosh,

I understand that you are interested in getting a copy of your allotment letter so in order to get the same, primarily you can request your college management to give you a copy of the same from the file they have on you, usually they have it in the system for each student.

If the above step doesn't work then you can choose to visit the counseling website of your concerned entrance exam and try downloading the same from there once again. The portal is active for previous candidates too so as they can download the necessary documents according to their perusal.

BEST WISHES!
