RRB Group D Registration and Application Guidelines

To ensure a smooth application process and avoid common errors, candidates must follow these detailed instructions carefully. Proper adherence to guidelines is vital for the RRB Group D registration.

• Read the Official Notification: Thoroughly review the entire CEN before filling out the online application.

• Educational Qualifications: Ensure all prescribed qualifications are met by the closing date (02.03.2026). Awaiting final results makes one ineligible.

• Online Submission Only: Apply only through official RRB websites. Be wary of fake sites.

• Single Application: Submit only one application to one selected RRB/Railway Zone. Multiple applications lead to rejection and debarment.

• Contact Information: Maintain an active mobile number and a valid personal email ID. These cannot be changed after account creation.

• Account Creation: Details like mobile, email, and chosen RRB cannot be modified later. DigiLocker or Aadhaar authentication is advised.

• Timely Submission: Apply well before the closing date to avoid last-minute issues.

Common Mistakes in RRB Group D Registration

RRB Group D registration requires careful attention to avoid rejection. Common errors often stem from mismatched details or improper uploads.​

• Personal Details Errors: Candidates frequently enter incorrect names, dates of birth, or contact info that don't match official documents, leading to disqualification. Invalid email or phone numbers prevent important updates from reaching applicants.​

• Document Upload Issues: Uploading blurry photos, wrong-format signatures, or incorrect certificates violates specifications and causes rejection. Many fail to use the mandatory live photo capture or proper file sizes as per guidelines.​

• Payment and Timing Mistakes: Forgetting to complete the fee payment leaves applications incomplete. Waiting until the last minute risks server issues or technical glitches.​

• Other Frequent Pitfalls: Providing wrong educational qualifications or skipping eligibility checks in the notification results in invalid submissions. Not reviewing the full form before submission prevents catching errors, as edits are limited post-submission.
