How to prepare
- Sign in black ink on white paper using your normal running/cursive handwriting - RRB rejects block letters, capital letters and disjointed signatures.
- Mark a 35 mm x 20 mm box on the paper, sign inside it, and scan the sheet at a minimum of 100 DPI so the signature meets the stated 140 x 60 px minimum.
- 140 x 60 px is a stated minimum, not a fixed size - do not shrink below it even if a generic resizer defaults to an exact-size output.
- Never submit a thumb impression in place of a signature; RRB explicitly lists this as a rejection ground for CEN 06/2025 and CEN 07/2025.
- This signature must match what is captured again at the CBT, Document Verification, Medical Examination and Appointment stages.

How to prepare
- Only upload this if you are an SC/ST candidate opting for the free railway travel pass - it is not required for every applicant.
- Use a PDF only; convert a scanned certificate into a PDF before uploading.
- Keep the PDF under 400 KB; RRB states no minimum, so a smaller, legible scan is fine.
- The certificate must be valid as on the closing date of the specific CEN you applied under (20.11.2025 for CEN 06/2025, 27.11.2025 for CEN 07/2025), not simply 'recent.'
