India Post GDS signature: what is specific to this exam

These India Post GDS 2026 rules come from secondary sources quoting “GDS Online Engagement, Schedule-II, July 2026”, page 23, last checked on 22 Oct 2026, not yet from the India Post notice itself. The India Post GDS form usually opens around January or August.

From our India Post GDS notes

• India Post GDS is one of the few forms that states its rules in shapes, not just sizes. The photo is 4:5 and the signature is 5:2. If you crop a photo to a square or a signature to a long thin strip, it will not match, even when the KB is right.
• Signature: JPG, recommended 300×120 px, 20–100 KB, 72–150 DPI, black or blue pen on white paper, signature filling 70–80% of the image, no borders or extra marks, no typed or digital signature.
• Sign on white paper with a dark pen. Sign slowly; the notice warns against shaky or pixelated signatures.
• Crop close to the ink in the 5:2 frame so it covers 70–80% of the image. Clean signature removes paper edges and shadows, which count as "extra marks".
• A tight 320×400 crop can save under 30 KB; Auto-fit raises the quality to cross it. If the signature is refused, check for a visible paper edge or a shadow.
