Hi Nagur,

JoSAA Reporting Centres are the centres released by the authorities having names of the venues where candidates have to report for the counselling. There are total 18 reporting centres for IIT seat allotment and 45 for NITs, IIITs and GFTIs.

You are required to report t the reporting centre on the prescribed date and time as doing otherwise will lead to disqualification.

I hope this information helps you.
