Pro Tips for RRB Success

Strict Background Rule

RRB notifications state that the background of the photograph must be plain white or very light-colored.

No Caps or Uniforms

Caps, hats, hoodies, or uniforms (such as security or defense uniforms) are not allowed in the photograph.

Black Ink Signature

Sign with a black ink pen on clean white paper. Crop to 3.5x1.5 cm and compress to the 20KB-70KB range.

Common Rejection Mistakes to Avoid

File Size Under 20KB

Many candidates over-compress their photos, making them smaller than 20KB. The RRB portal will block files under 20KB.

Wearing Sunglasses or Caps

Uploading outdoor snapshots with goggles, caps, or headwear. Photos must be professional studio-style portraits.

Using Faint Blue Ink

Signing with a light blue pen, which fades during compression and becomes illegible, risking application rejection.

Official Photography & Scanning Guidelines

✓
Studio Lighting: Take the photo in a bright room against a white wall to eliminate facial shadows.
✓
No Goggles/Hats: Ensure your head is bare and eyes are fully visible without sunglasses or tinted spectacles.
✓
Black Ink Signature: Always sign in black ink on unruled white paper for high contrast.
✓
Recent Image Check: Your photograph must be recent, taken within three months of the registration date.
