Lost obc ncl certificate which I give at the time off Jee registration in train than is it possible to produce new obc certificate at reporting center.o r please suggest some another way

@ sonu 
for that reason its suggested to keep the xerox of these certificate with you , if you have xerox then u can produce that by taking an undertaking , 
otherwise write a mail to the jee council about it and ask them for some time , in that time period quickly arrenge the copy of your obc ncl certificate again , and in these last time its must required thing , 
only the jee council board can help u with this matter , 
so, do the mail as soon as possible with the details , and u can also get your copy of obc ncl certificate online if u have the registration number , 
if not , then u have to make anathor one new by visiting the respoective offices , 
HOPE IT CLEARS YOUR DOUBT 

ALL THE BEST ..
