Udyog Aadhar, now replaced by Udyam Registration, was a government initiative introduced by the Ministry of Micro, Small, and Medium Enterprises (MSME) in India to simplify the registration process for small and medium businesses. It provided entrepreneurs with a unique identification number and a digital certificate, making it easier to access various government schemes, subsidies, loans, and incentives designed to promote business growth. The registration was free of cost and could be completed online with minimal documentation, primarily requiring an Aadhaar number. By easing bureaucratic hurdles, Udyog Aadhar played a crucial role in empowering MSMEs, fostering entrepreneurship, and driving economic development in India.
