Udyog Aadhar is also known as Udyog Aadhar memorandum (UAM). Udyog Aadhar was first launched in September 2015 by the Ministry of Micro, Small and Medium Enterprises. The purpose of Udyog Aadhaar was to allot MSMEs with a unique identification number that would allow them to access various government benefits such as subsidies and tax benefits. To obtain Udyog Aadhar, MSMEs had to provide their PAN and bank account details along with other relevant information.
