Recent RRB notifications tell candidates not to upload a pre-existing photograph. The portal captures a live image using a webcam or phone front camera, and candidates must not photograph a printed or digital old photo.
Signature requirements
Use black ink on white paper and sign in running handwriting. Block, capital and disjointed-letter signatures are not accepted. The complete signature should be clear and centred.
Always check your CEN
Railway Recruitment Boards can change requirements between Centralised Employment Notifications. Use the live application and the CEN for your recruitment as the final authority.
This guide is scoped to Official RRB CEN application instructions. Requirements can change between application routes and notifications; the instructions shown in your live application take priority.
