Electronic Verification Code ensures identity verification for e filed income tax returns via multiple authenticated generation modes. Procedural standards require the Electronic Verification Code (EVC) to verify identity for electronically filed income tax returns. The Principal DGIT (Systems) prescribes generation, storage and validation procedures; the EVC is PAN unique, time limited, stored against the PAN, usable once per return, and will be generated via authorized modes such as net banking redirection, Aadhaar OTP, ATM generation, delivery to registered contact points, and pre validated bank or Demat details.
