Keeping these documents updated will ensure a smooth application process and help avoid potential issues during verification.

What Documents Do You Need to Update CUET UG Registration 2026

How to Update These Documents — Step by Step

How to Update Aadhaar Card

1. Visit the official portal of issuing authority (for Aadhaar, the portal of Unique Identification Authority of India — UIDAI) or nearest Aadhaar-service centre.
   

2. Request corrections/updates for details that must match your school records: name, date of birth (as per Class 10 certificate), father’s name, address.
   

3. Update your photograph if needed (sometimes Aadhaar requires a recent photo for verification).
   

4. Pay any requisite “correction” fee (if applicable) and submit required proof/documentation (birth certificate or Class 10 certificate for date of birth; address proof; ID proof for name/address changes etc.).
   

5. Wait for Aadhaar update confirmation/acknowledgement and download the updated Aadhaar PDF/card once ready.

How to Update / Renew UDID Card (for PwD candidates)

1. If you have a UDID card/disability certificate, check its validity date. If expired or nearing expiry — plan to renew.
   

2. Contact the issuing authority or hospital/rehabilitation centre that issued the disability certificate; apply for renewal or fresh certificate if required.
   

3. Ensure the certificate mentions correct name, disability type, dates, and is signed/stamped as per norms.
   

4. Once renewed, download or obtain the valid UDID / disability certificate — you’ll need to upload this during CUET UG application.

How to Update or Acquire a Valid Category Certificate (EWS / SC / ST / OBC-NCL)

1. If you already have a certificate — check its validity (for some categories, certificates may have validity). If outdated or details changed, apply for an updated certificate from the relevant issuing authority (e.g. Tehsildar / Revenue Office / Competent Authority).
   

2. Ensure that the name, address, and category details are correct as per your Aadhaar / school records.
   

3. Obtain printed, signed and stamped copy of the renewed category certificate.
   

4. Keep both digital (scanned) and original copy ready, since the application requires upload of digital version.

Common Mistakes to Avoid in CUET UG Online Form 2026

1. Using Aadhaar details that do not match your school (Class 10) certificate — e.g. different date of birth, name mismatch. That can lead to application rejection.
   

2. Uploading expired UDID / disability certificate (for PwD) — ensure validity.
   

3. Using outdated or wrong category certificate for reservation — may lead to rejection or loss of reservation benefit.
   

4. Waiting till the last moment — resulting in delays when offices are busy.

Therefore, Students are strongly advised to update their Aadhaar, UDID, and category certificates before the CUET UG 2026 application process begins. This proactive measure is essential to prevent potential problems such as mismatches, application rejections, or delays. Aspirants must ensure that all personal details and supporting documents are accurate, valid, and current. Completing these necessary updates ahead of time guarantees a smooth and easy application experience, securing your eligibility for admission to undergraduate programs in the participating universities.
