Rules for each document
Live photograph (webcam / front camera)
- “Candidates are not required to upload a pre-existing photograph while applying.” The form captures a live photo — no size / KB / format stated.
- “Live photo must be taken with pure plain white background without any scenery, plants/human or animal picture.”
- Wear non-white clothing, preferably plain dark colour; proper dress covering shoulders and chest.
- Head should occupy at least 50% of the photo; elbow, below-elbow and below-chest portions should NOT be visible. Eyes fully open.
- No cap, mask, glasses/spectacles. Do not photograph a printed or digital existing photo.
Signature
- Official: “File size: Between 30 KB and 49 KB”, “Image dimensions: Minimum 140 pixels (width) × 60 pixels (height)”, “minimum resolution of 100 DPI”, “JPG/JPEG only”.
- “The scanned signature must be positioned within the designated scan box on the application form : Box size: 35 mm (width) × 20 mm (height). The signature image should be centered within this box” — a placement box, not a stated image size.
- Black ink pen on white paper, in running handwriting (cursive / joined letters) — NOT in BLOCK, CAPITAL or DISJOINTED letters.
- Rejected for: non-white background, non-black ink, block/capital letters, poor resolution, incomplete signature, thumb impression in place of signature, blank.
SC/ST certificate (for free railway travel pass)
- “The document must be in PDF format only.” “File size should be less than 400 KB.” No minimum stated.
- Must be the latest valid certificate as on the closing date of the online application.
Annexure VIII (photo-mismatch declaration signed by a Gazetted Officer)
- Only if the live photo does not match the ID. No format or size is stated.
Printed passport photo for CBT / DV / medical
- “candidates must bring a colour passport photograph that is not older than two months from the date of the CBTs/DV/ME”.
General instructions
- Uploads at application: only the signature and (SC/ST candidates) the caste certificate. The photo is captured live.
- Shortlisted candidates must later upload true-colour scans of photo and signature before their DV date at oirms-ir.gov.in/rrbdv — no size is published for that step.
- Notices are on the unified site rrb.indianrailways.gov.in (old regional sites did not respond). Its firewall rejects direct PDF links without a browser session, so link users to the RRB page rather than the PDF.
- Para 14.4 (photo), 14.5.1 (signature), 14.5.2 (SC/ST certificate) in both CENs.
