🖼️ New Photo & Signature Rules (Important!)

The UPSC has updated its specification requirements for applicant images to reduce discrepancies, rejections, and identity mismatches:

• Live Photo Capture Suggested: Candidates are strongly advised to use a recent photo taken within the last 30 days.
• Photo Size: 10 KB to 300 KB (JPEG / JPG)
• Text on Photo: Photo must include the candidate’s name and date written clearly below the image.
• Neutral Background: Plain, light-colored background recommended for clarity.
• Face Coverage: Full face, clearly visible from both ears (no caps / sunglasses).
• Signature File: between 4 KB to 30 KB in JPG / JPEG format.

In recent application cycles, UPSC also emphasizes strict photo checks at exam centres to prevent impersonation and mismatch issues. Always review your uploaded photo carefully before submission.

📌 Aadhaar & Identity Verification

UPSC requires that all personal details match exactly with government IDs like Aadhaar, Passport, or Driving License. The most common errors that lead to rejection are mismatches in:

• Name spelling
• Date of birth
• Gender / category entries
• Parent / guardian names

While Aadhaar is not always mandatory, the data you enter must match the ID you plan to carry on exam day. If you are yet to update your name/date of birth on Aadhaar, do it well before form submission to avoid rejection.

🏙️ Exam Centre Preference & City Allocation

In the UPSC CSE 2026 application, you will be asked to select up to 5 exam centre preferences. These must be chosen carefully since the final allocation may depend on availability at those centres.

Tips for selecting exam centres:

• Choose cities that are logistically easier to reach.
• Prefer centres with historically high seat availability.
• Avoid too many remote/lesser known centres unless necessary.

UPSC tries to allocate candidates to their highest preferred centre and avoids making major changes unless absolutely necessary.

📄 Required Documents Checklist

• Recent Photograph (with name & date printed below)
• Signature File (8 MB limit)
• Category Certificate (if applicable)
• Disability Certificate (if applicable)
• Address Proof (Aadhaar / Passport / Voter ID)

Ensure that all documents are clear, properly aligned, correctly sized, and readable. UPSC may reject applications with blurry or improperly formatted uploads.

⚠️ Common Mistakes to Avoid

• Uploading an old or blurred photograph that doesn’t match your current appearance.
• Mismatch between date of birth in application and official ID.
• Incorrectly formatted signature.
• Selecting unavailable exam centres or exceeding the maximum allowed choices.
• Missing category or special certificates (if applicable).

💡 Tips for Smooth Form Submission

• Always fill UPSC forms on a desktop or laptop for better accuracy.
• Use the latest version of Chrome / Edge while uploading images.
• Preview the entire form before clicking “Submit”.
• Take screenshots of the success message and payment receipt.

Final Summary

The UPSC CSE 2026 application process is designed to be precise and transparent. The latest updates, especially in photo guidelines and identity verification, focus on reducing impersonation and errors before exam day. If you follow the steps carefully, avoid common pitfalls, and double-check all document uploads, you significantly increase your chances of a smooth and accepted application.
