UPSC Form Filling New Rules 2026: Step-by-Step Guide, URN, CAF & Application Updates

The Union Public Service Commission has introduced several important changes in the Civil Services Examination 2026 application process. The new system focuses on simplification, faster verification, and better transparency. Candidates must carefully understand these updated rules before submitting their forms, as mistakes or missing details may lead to rejection.

This article explains all the major changes, new modules, document requirements, and important instructions in simple language to help you complete your application smoothly.

As per the official notification, the last date to submit the online application is 24 February 2026, 6:00 PM.

Introduction of Four-Stage Online Application System 2026

UPSC has redesigned its application portal into four modules. Three modules are common for all exams, while one is exam-specific.

1. Account Creation

Candidates must first create an account on the official UPSC online portal using basic details like email ID and mobile number.

2. Universal Registration Number (URN)

After registration, a Universal Registration Number is generated.
This URN remains permanent for life and is used for all future UPSC exams.

You need to create the URN only once. For every new exam, you will not register again.

3. Common Application Form (CAF)

This form collects general details such as:

• Personal information

• Educational qualification

• Identity proof

• Address

• Category details

Since it is common, you do not have to refill it for every exam.

4. Examination-Specific Module

This is the final step where candidates choose:

• Exam centre

• Fee payment

• Service preference

• Optional subject

• Medium of exam

Only this part changes for each examination.

Live Photo Capture is Now Mandatory

One of the biggest updates in 2026 is live photograph capture.

Candidates must:

• Upload a recent photo

• Capture a live photo during form filling

Both photos must be clear and match your appearance. Blurred or mismatched images may cause rejection.

This step is introduced to prevent impersonation and ensure identity verification.

New Signature Upload Rule

Applicants must:

• Sign three times on white paper using black ink

• Scan and upload the signature

The signature must be clear and readable. Incorrect or unclear uploads may invalidate the application.

Aadhaar-Based Verification Encouraged

UPSC strongly advises candidates to use Aadhaar as their primary identity document.
This helps in quicker verification and smoother authentication during the exam process.

Other valid IDs include:

• Voter ID

• PAN card

• Passport

• Driving licence

No Correction or Withdrawal After Submission

This is a very strict rule for 2026.

Once the application is submitted:

• No editing allowed

• No correction allowed

• No withdrawal allowed

Therefore, candidates must carefully check every detail before final submission.

One-Time URN Profile Update Facility

UPSC allows candidates to update their URN profile only once.

Important points:

• Changes will not affect already submitted applications

• Updates apply only to future applications

So make sure your details are correct before locking the profile.

Online Admit Card Only

Admit cards will not be sent by post or email.

Candidates must:

• Download e-Admit Card from the UPSC website

• Carry valid photo ID to the exam centre

Face Authentication at Exam Centre

UPSC has introduced mandatory face authentication at exam venues.

Every candidate must undergo:

• Face verification

• Identity check

• Frisking

Arriving early is recommended to avoid delays.

Key Points Candidates Must Remember

• Register once using URN

• Fill CAF carefully

• Upload live photo and clear signature

• Use Aadhaar for faster verification

• Double-check form before submission

• No correction or withdrawal allowed

• Download admit card online

Conclusion

The new UPSC form filling system for 2026 aims to make the process more streamlined and secure. While the modular system reduces repetitive work, stricter rules mean candidates must be more careful during submission.

Understanding the URN system, live photo capture, signature upload, and no-correction policy is essential. Preparing documents in advance and filling the form early will help avoid last-minute issues.

A small mistake can cost an entire year, so take your time and submit the application only after verifying every detail.
