Hi.

State code of eligibility means the code of the State from where the candidate has passed Class XII (or equivalent) qualifying examination by virtue of which the candidate becomes eligible to appear in JEE (Main) 2021.

If a candidate has passed Class XII (or equivalent) qualifying examination from one State but appeared for improvement from another State, the candidate’s State code of eligibility will be from where the candidate first passed the Class XII.

I hope this answers your query.

Good Luck
