Key Requirements for the Photograph

To ensure the automated system accepts your photo, check that it complies with these rules:

1. Background: A clean, plain white or light-grey background is required. Photos taken in front of textured walls or outdoor landscapes will be rejected.
2. Facial Expression: Maintain a neutral expression with closed mouth and eyes looking straight ahead. Do not smile, frown, or tilt your head.
3. Eyewear: Spectacles are permitted only if they have clear lenses and do not reflect the camera flash. Sunglasses, tinted glasses, or thick frames are not allowed.
4. Recency: The photo must be fresh, showing your current appearance. Ensure it is not older than 10 days from the date of the application opening.

Strict Rules for the Signature

• Ink Color: Sign clearly on white, unruled paper using a black ink pen. Refrain from using blue ink, sketch pens, or gel pens that run, as they lead to blurry scans.
• Handwriting Style: The signature must be in your normal running handwriting. Do not write your name in CAPITAL LETTERS, block letters, or with decorative flourishes.
• Cropping: Crop the scan tightly around the signature text to avoid excess empty space, which can distort the dimensions.

Frequently Asked Questions

Can I write my name and date on the RRB NTPC photo?

Unlike some state exams, RRB NTPC notifications do not strictly require candidate names and photo dates at the bottom of the picture. However, a clean, un-dated photo that matches the current appearance is fully acceptable.

Why is the portal rejecting my signature even when it is 15KB?

This usually happens because the dimensions do not match. The signature must have an aspect ratio matching 140 x 60 pixels. If you upload a square 15KB image, the portal will reject it.

Can I upload a photo wearing a cap or religious headwear?

Caps, hats, and hoods are prohibited. Religious headwear is allowed but it must not cover any part of your face (ears, forehead, and chin should remain fully visible).

Should I scan the photo or take a picture with my mobile phone?

Scanned files are always preferred because they avoid glare and shadows. If you must use a phone, take the photo in bright daylight, stand straight, and use a scanner app to flatten and crop the final image.
