Common mistakes to avoid
- Blue-ink or capital-letter signatures — RRB wants black ink, running hand
- A busy or coloured background instead of plain white
- Missing the printed date on the photo when the notice requires it
Pro tips
- RRB file-size limits vary a little by zone — check your notification and match it
- Keep the face at 50–60% of the frame with both ears visible
- Target the middle of the range so a re-check never trips the limit
