Hello and welcome to exampundit . Ascertaining the identities of candidates at examination is critical for fair conduct of Railway Recruitment Boards (RRBs) examination and prevention of attempts at impersonation. For candidates also the use of Aadhaar is a convenient and hassle free mode of verification of identity.
Accordingly, Railway Recruitment Boards have decided that in all future railway recruitments, the applicants shall be required to furnish his /her 12 digit Aadhaar number or 28 digit Aadhaar registration receipt at the time of filling up the application. During the exam, through a biometric attendance system, their fingerprints can be collected and matched with the one stored with the Aadhaar server. All eligible candidates desiring to apply for the posts of Railway Recruitment Boards are requested to visit the Aadhaar Enrolment centers to get them enrolled for Aadhaar.
