Hello,

No, your form will not get rejected because of this.

If the Aadhaar number and personal details match , the photo on your old Aadhaar is not a problem . Many students use Aadhaar with an old photo, and NTA accepts it as long as the details are correct.

Since you have not done final submission yet , you can try once more to edit the Aadhaar number. If the portal still does not allow changes, just continue with the form. It will not cause rejection.

For the exam day, carry:

  • Your updated Aadhaar (new one)

  • The JEE admit card

This is enough. There is no risk of rejection.

Hope it helps !

The JEE Mains 2025 question paper will be available after the exam is conducted. You can check the website Careers360 for the PDF once it is released.

I can provide you previous years’ JEE Main question papers for practice. Here's the link:

Hi there,

It is possible that the name mismatch to create problems during the JEE Main registration, document verification, and counselling process. NTA is quite strict about data consistency, and your details must match exactly. It would be better if you apply to correct the name as soon as possible at a Permanent Aadhaar Seva Kendra, or you could prepare a legal affidavit as a temporary solution.

Hope it helps!!!
