After applying, RRBs usually publish an application status list on the regional RRB website before the admit card stage. Check whether your application is provisionally accepted or rejected by entering your registration number and date of birth. Applications are commonly rejected for an invalid photo, a signature mismatch or a failed fee payment. If your application is rejected, most RRBs also show the reason on the status page. Always check the status on the official RRB website, not on third-party links.
