Importance of Updating Documents Before Registration

Over the past few admission cycles, one of the major reasons for application rejections has been mismatched Aadhaar details. Many candidates faced difficulties because their demographic information in Aadhaar did not match their Class 10 or 12 certificates. Therefore, understanding how to update Aadhaar for JEE Main 2026 application is crucial for avoiding errors during verification.

NTA has advised students to ensure that:

• Their name, date of birth, gender, and address in Aadhaar exactly match their academic certificates.
• Any spelling errors or outdated details should be corrected through the UIDAI self-service portal or Aadhaar enrolment centres well before registration opens.
• Photographs and biometric details should be recent and clear to avoid authentication failures.

These steps ensure smooth Aadhaar authentication during the application process and prevent the need for multiple corrections later.

UDID and Category Certificates: Essential Verification Documents

Another critical area of document verification involves UDID certificates (for candidates with disabilities) and category certificates (for EWS/SC/ST/OBC–NCL applicants). The NTA has clarified that these certificates must be valid, issued by competent authorities, and updated for the current financial year.

• For candidates under reserved categories, renew category certificate (SC/ST/OBC/EWS) for JEE 2026 well in advance to avoid last-minute delays.
• Certificates must mention the candidate’s name, caste/sub-caste, issuing authority, date of issue, and must be signed and stamped appropriately.
• UDID certificates must be obtained through the official UDID portal and carry the necessary QR code for authentication.

For additional preparation support, including topic-wise notes and practice material, candidates can visit Notes, MCQs, and Videos.

Expert Insights: Avoid Common Mistakes

According to Ramesh Batla, Senior Academic Counsellor at FIITJEE, a large number of candidates lose valuable opportunities because of incorrect or incomplete document submissions.

“Every year, nearly 4–5% of JEE Main applications face delays due to Aadhaar–certificate mismatches. Candidates should not treat document verification as a last-minute task. Updating Aadhaar and certificates at least a month before registration can save them from unnecessary complications,” Batla explained.

His advice echoes NTA’s emphasis on early document preparation, especially for those planning to apply for both January and April sessions.
