CDS Application Form

UPSC CDS applications are submitted online at upsconline.nic.in. Since 2025 UPSC uses a four-module portal, and three of those modules can be completed before the notification is even published.

Important dates — CDS (II) 2026

Application fee

₹200. Female candidates and SC / ST candidates are exempted.

The URN and the Common Application Form

UPSC issues every candidate a Universal Registration Number (URN), which is registered once in a lifetime and is common to every UPSC examination. The Application Number, by contrast, is generated per examination and changes each time. Keep both — UPSC asks for them in any future correspondence.

How to apply

1. Create an account on upsconline.nic.in.
2. Complete Universal Registration to generate your URN. This can be done at any time — you do not need to wait for a notification.
3. Fill the Common Application Form (CAF) with your personal details, qualification and category, and upload the supporting documents. A live photograph must be captured at this stage in addition to the uploaded photo.
4. Open the examination-specific module during the application window, choose your centre and options, pay the fee and submit.

UPSC advises using an Aadhaar card as the identity document, because it verifies automatically and avoids manual checks later.

Correcting your application

UPSC provides a one-time facility to update the URN profile. Changes made to the profile do not flow back into applications already submitted — they apply only to applications made after the profile is re-locked. This catches people out every cycle.
