To avail the benefits of the PM Kisan Scheme, farmers need to register themselves on the official PM Kisan portal using their Aadhar card. The Aadhar card is a unique identification number issued by the Government of India to every resident of the country. It serves as a proof of identity and address and is mandatory for availing various government schemes and services. Once a farmer has registered on the PM Kisan portal using their Aadhar card, they can check their PM Kisan status to know if they have been approved for the scheme and if the funds have been transferred to their bank account. The PM Kisan status can be checked online through the official PM Kisan website or by visiting the nearest Common Service Center (CSC).
