The window runs from 27 to 29 November 2026 and closes at 11:50 PM on the last day. NTA will activate the link on jeemain.nta.nic.in.

Q: My Aadhaar and Class 10 details differ. Which one should I follow?

Follow your Class 10 marksheet exactly. Mismatched names and dates of birth can cause trouble at document verification.

Q: Can I change my mobile number or photo in the correction window?

No. Mobile number, email ID, address and photograph stay locked, so check them before you submit.

Q: How many times can I correct my JEE Main form?

Only once. NTA gives a one-time correction facility, so review every field before you click Submit.

Registration closes on 22 November 2026, and the late window runs from 23 to 26 November with a ₹500 late fee.
Mobile number, email ID, address and photograph cannot be changed in the correction window.
NTA gives a one-time correction facility, so fix every error in a single submission.
An unpaid correction fee means your changes will not be saved.

JEE Main 2027 Form: Top 10 Common Mistakes and Fixes

Most rejections and delays come from ten avoidable errors. Check each one against your documents before you submit.

No.	Common Mistake	How to Fix It	Fixable in Correction Window?
1	Mismatched or outdated documents	Match personal details to your Class 10 marksheet, not Aadhaar. Use a current category certificate.	Partly
2	Typing errors in name	Correct one of name, father's name or mother's name.	Yes (one only)
3	Invalid mobile number or email ID	Use your own active number and a permanent email at the start.	No
4	Poor photo and signature upload	Follow the size, format and clarity rules in the NTA bulletin.	Photo: No. Signature: check bulletin
5	Wrong Class 10 and 12 details	Re-check marks, board and passing year against your marksheet.	Yes
6	Wrong category or sub-category	Change the category or re-upload the certificate, not both.	Yes (fee may apply)
7	Wrong exam city, paper or medium	Pick from the options NTA offers. A foreign city or an added paper raises the fee.	Yes (fee may apply)
8	Incomplete payment	Finish the payment before 22 November, or pay the difference in the correction window.	Yes
9	Skipping the correction window	Log in on 27 November and re-check every field, even if you feel sure.	Not applicable
10	Filing more than one application	Submit one application only. NTA may treat duplicates as unfair means.	No

JEE Main 2027 Form Correction: What You Can Change

You can edit exam city, paper, medium, category and Class 10 and 12 details in the correction window.

Name: only one of your name, father's name or mother's name.
Category and PwD status: change the entry or re-upload the certificate, not both.
Identity details: editable only if your ID is not Aadhaar.
Date of birth and signature: sources disagree, so check the NTA notice.

Type of Change	Extra Fee
Exam city in India, medium, academic details	No extra fee
Category change from SC/ST/PwD to General or OBC-NCL	Fee difference (male: ₹500 to ₹1,000)
Adding another paper	Fee for the added paper
Exam city outside India	Fee difference (General male: ₹1,000 to ₹5,000)

Pay the correction fee within the window, because unpaid corrections will not be saved.
