Hi Smit,

I understand that you have lost your CAP allotment confirmation letter and the sweets to know the whereabouts from where you can download the same again for your perusal and so to answer your question you need to login into the official website of the concerned authorities of the examination or other organisation with your login credentials and download the allotment letter regarding the same and if it is not available then it is advise that you address this matter to the competent authorities through post while stating your dishu and request him to issue you a copy of your CAP allotment letter through post or via email at the earliest for your further perusal.

Best wishes!
