Railway Recruitment Boards (RRB) maintain some of the strictest document upload verification filters in India. Because RRB recruitment drives involve over 1 crore applications for NTPC and Level-1 (Group D) vacancies, their automated intake checks immediately reject files outside the 30KB - 70KB bracket.
Official RRB File Specifications Table
| Document Type | Format | File Size | Key Conditions |
|---|---|---|---|
| Color Passport Photo | JPG / JPEG | 30 KB to 70 KB | Taken within last 6 months, light background |
| Running Signature | JPG / JPEG | 30 KB to 70 KB | Black or blue ink, no capital letters |
| SC / ST Travel Pass Certificate | PDF Only | Under 500 KB | Legible official seal and digital signature |
Compress your SC/ST certificates easily with PhotoSePDF Compress PDF to guarantee sub-500KB compliance.
RRB Centralized Employment Notice (CEN) Detailed Standards
Railway Recruitment Boards across all 21 RRB divisions (Allahabad, Mumbai, Secunderabad, Chandigarh, Kolkata, etc.) use unified application software. Here are the core specifications:
- Photograph Age: The photograph must be recent, taken within the last 6 months from the date of the employment notification. Old school photographs are strictly flagged during document verification (DV).
- Facial Hair & Appearance: Maintain the same facial appearance (beard, mustache, or clean-shaven) on exam day as shown in your uploaded application photograph. Discrepancies lead to biometric delays at computer exam centers.
- Signature Legibility: Initial-only signatures (such as "R.K.") are strictly prohibited. The signature must feature your complete, legible surname or customary signature.
Free Travel Authority Pass Certificate Rules (SC / ST Aspirants)
Candidates eligible for free sleeper-class railway travel passes must upload their caste certificate in PDF format:
- Must be an authentic government-issued certificate with valid registration number and issuing authority seal.
- File size must not exceed 500 KB.
- Use PhotoSePDF Compress PDF to compress your scanned PDF without degrading stamp or signature legibility.
RRB Document Verification (DV) Scrutiny Standards
Clearing the Computer-Based Test (CBT 1 & CBT 2) is only half the battle. During the final Document Verification round, railway administrative officers match your original identity proofs against your uploaded application images:
- Physical Resemblance: If you wore a thick beard during application and appear clean-shaven during DV, verification officers will subject you to secondary biometric fingerprint matching. It is strongly advised to maintain consistent facial grooming between application and exam dates.
- Signature Stroke Verification: On exam day, invigilators will ask you to sign the attendance sheet and admission certificate in their presence. If this physical signature fails to match the stroke characteristics of your uploaded 30KB-70KB application signature, your candidature will be suspended pending handwriting forensic analysis.
- Clear Document Scans: Educational certificates (10th standard matriculation marksheet for date of birth verification, ITI/Diploma certificates for ALP/Technician) must be scanned at 150-200 DPI in clear greyscale PDF under 500 KB.
Frequently Asked Questions: Railway Recruitment Board Uploads
Q: What is the exact photo size range for RRB NTPC and Group D?
The official RRB notification stipulates that color photographs must be strictly between 30 KB and 70 KB in JPG/JPEG format, with dimensions of 35mm x 45mm. Files smaller than 30 KB or larger than 70 KB are automatically blocked by the server.
Q: Can I take a photo wearing my prescription spectacles?
No. RRB notifications strictly prohibit the wearing of spectacles or tinted glasses in application photographs to prevent flash reflection from hiding pupil characteristics.
