The Ministry of Railways announced on Wednesday that with effect from July 1, Tatkal tickets booked through IRCTC’s official website and mobile app will be available only to users authenticated with Aadhaar.

Further, Aadhaar-based OTP authentication will become mandatory for Tatkal bookings made online starting July 15.

Tatkal tickets booked at computerised Passenger Reservation System (PRS) counters and through authorised agents will require OTP authentication sent to the mobile number provided by the user at the time of booking. This provision will also come into effect from July 15.
