When the JEE Main form asks for the pin code of your school, it typically refers to the postal code of the location where your school is situated. You should enter the pin code of the area where your school is physically located.

Hello

Yes, they ask for school pin code which you can easily get from the school's address mentioned.

If they have mentioned School pin-code, then you have to mention your school pin code and not your residence's pin code
