Hello,

Yes, E-Aadhaar Card is valid document so you can carry a colour print out copy of E-adhaar card generated from UIDAI website to the examination center. But the colour print out of Voter ID cannot be accepted. Your voter ID must be a PVC Voter ID card, a colour print out of it on A4 size paper will not be accepted so we would suggest you to carry E-Adhaar card instead of Voter ID card to RRB NTPC examination center.
