RC Mobile Number Update Online 2026: Vehicle owners across India should pay attention to an important update related to Pollution Under Control (PUC) certificate renewal. According to information shared by a pollution checking center operator from Durgapur, West Bengal, vehicle owners are increasingly facing issues while renewing their pollution certificates because the mobile number linked with their Vehicle Registration Certificate (RC) is either outdated or no longer active.
As per the latest verification process being implemented through the Parivahan system, OTP-based authentication is becoming mandatory for several vehicle-related services. In many cases, PUC renewal and verification require successful OTP validation on the mobile number registered with the vehicle’s RC.
