Hello,
No, it’s not compulsory to fill the APAAR ID in the JEE Main application form right now.
If your APAAR ID shows a “credential mismatch” error even after entering the correct number, don’t worry, you can simply leave it blank and continue filling the form.
-
The APAAR ID field is optional for most students.
-
It’s mainly for linking your academic records under the Academic Bank of Credits (ABC) system.
-
The mismatch often happens if your Aadhaar details or school record name format differ.
So, you can submit your JEE form without the APAAR ID, and it won’t affect your application.
