Udyog Aadhaar and Udyam: Know the Difference


The Government of India has undertaken various initiatives to boost the MSME sector in India, such as providing business loans at attractive business loan interest rates. One such initiative was Udyog Aadhaar.

As the pandemic adversely impacted small businesses, to help them recover, the Ministry of Micro, Small, and Medium Enterprises introduced a new process of MSME/Udyog Aadhaar registration known as Udyam Registration (Udyam) on July 1, 2020. Udyam Registration has now replaced Udyog Aadhaar.

Udyog Aadhaar

Udyog Aadhaar was a twelve-digit Unique Identification Number provided to MSMEs who got registered on the MSME portal. This registration helped MSMEs access different government schemes introduced to benefit them through projects like business loan at affordable business interest rates.


Udyam is an online registration portal introduced by the Government of India to benefit MSMEs. The earlier Udyog Aadhaar has been modified to create the updated version – Udyam as a more simplified MSME registration process for availing faster access to government schemes and programs. An enterprise that comes under the purview of the definition of an MSME can avail of Udyam Registration via the Udyam Registration portal and continue to benefit from this process, like getting business loans with attractive business interest rates.

Many people tend to get confused between the two processes – Udyog Aadhaar and Udyam.

These two initiatives differ in their features. The key differences between the two portals are as explained below.
