THIRUVANANTHAPURAM: One Time Password (OTP) has been made compulsory for the free ration supply announced as part of the lockdown. In order to get ration from Monday, one has to produce the OTP received on the mobile number linked with the ration card.

The OTP system was resumed on the centre's guideline. The measure is taken in light of the misuse of ration portability system.

However, Ration Dealer's Association said this measure won't be accepted.
