Mastering the UPSC Triple Signature Requirement: Official 2026 Guidelines

If you are a Civil Services aspirant, you already know that the Union Public Service Commission (UPSC) is extremely strict about document uploads. While many candidates successfully upload their photographs, thousands face rejection or technical glitches due to the unique Triple Signature mandate.

To help you navigate the UPSC portal without errors, we have compiled this expert guide based on the latest recruitment standards. Following these steps will ensure your signature.jpg is accepted on the first attempt.

The “Triple Signature” Rule: What Is It?

Unlike other government exams that require a single scanned signature, the UPSC requires a vertical compilation.

Official Requirement: You must upload three identical signatures signed in black ink on white unruled paper in one vertical column.

This means you should not scan three separate files. Instead, you sign three times, one below the other, on a single sheet of paper and scan them together as one image.

Technical Specifications for signature.jpg

The UPSC portal uses automated validators that check for specific metadata. If your file doesn’t match these “Notes” from the official handbook, the “Upload” button will remain greyed out or show an error.

• Allowed Signature Size: Your file must be between 20 KB to 100 KB.
• File Format: The portal strictly accepts the JPG format. Do not use PNG or PDF.
• File Name: The file name should be signature. Avoid using names like “mysign.jpg” or “scanned_copy.jpg.”
• Dimensions: The height and width of signature image must be between 350 and 500 pixels. A perfect square (like 450×450 px) is the safest choice for the layout.

Pro-Tips for a “Portal-Ready” Signature

To maintain high EEAT (Experience, Expertise, Authoritativeness, and Trustworthiness) in your application, follow these physical preparation steps:

1. Use the Right Ink: Only Black Ink is permitted. Blue or gel pens often fail the contrast test during the automated screening process.
2. Paper Quality: Always use white unruled paper (plain A4 or printer paper). Any lines, grids, or patterns in the background will interfere with the legibility of your signature.
3. Vertical Alignment: Ensure your three signatures are aligned straight. If the column is tilted, the cropping tool might cut off the edges of your name.
4. Avoid Shadows: When taking a photo of your signatures with a mobile phone, ensure no shadows are falling on the paper. Natural daylight is best for a crisp, white background.
