Udyog Aadhaar vs Udyam Registration — Key Differences Explained
Udyog Aadhaar was the old MSME registration system (2015–2020). Udyam Registration replaced it on 1 July 2020. Old Udyog Aadhaar certificates are no longer accepted for government scheme benefits, bank loans, or tender eligibility. If you have an old certificate, you must re-register on the Udyam portal.
Millions of Indian businesses registered on the Udyog Aadhaar portal between 2015 and 2020. In 2020, the Government of India completely revamped the MSME registration system with the launch of Udyam Registration. The two systems are not compatible — Udyog Aadhaar holders must migrate to Udyam to access current MSME benefits.
Understanding Each Term
What is Udyog Aadhaar (Old System)?
Udyog Aadhaar was a simple self-declaration-based MSME registration introduced in 2015. It required only Aadhaar number and basic business details. Over 80 lakh businesses registered under this system. Since July 2020, it has been phased out and old certificates are not valid for current schemes.
