  • Updated On 22-August-2025

The basic process for MSME was Udyog Aadhar registration. However, it has now been replaced by Udyam registration. Migrating Udyog Aadhaar to Udyam Registration is an important step for every Micro, Small and Medium Enterprise (MSME) to comply with government regulations. If you had registered your business under Udyog Aadhaar before June 2020, it is necessary to migrate to Udyam registration to continue receiving benefits like subsidies, loan schemes, etc.

The Udyam Registration Portal launched by the Government of India, all existing Udyog Aadhaar holders have to adopt this new system to avail various MSME benefits smoothly. This change is aimed at streamlining the registration process and providing better benefits to registered businesses. Business Aadhaar, also known as Udyog Aadhaar, is a unique 12-digit identification number issued to business entities. 

What is Udyog Aadhaar?

If you run a small or medium-sized business in India, you must have heard the term Udyog Aadhaar. The Ministry of MSME introduced Udyog Aadhaar in 2015 as a simple registration process for MSME. Udyog Aadhaar is a government unique identification number provided to micro, small and medium enterprises (MSME) in India.  It did this by assigning small enterprises a unique 12-digit identification number. This number was similar to the Aadhaar number.

Udyog Aadhaar simplified the process of MSME registration by replacing lengthy paperwork with a one-page online form. It was aimed at enabling small businesses to register themselves and avail various government schemes.

What is Udyam Registration?

Udyam Registration is the official government registration process for MSME in India. It launched in July 2020 as a new and improved version of Udyog Aadhaar. This system is simple, paperless, online and requires minimal documentation. using PAN and GST based verification to ensure accuracy.

After registering with Udyam, the MSME receives the MSME certificate as soft copy via email. It contains a QR code which helps to verify the certificate and get detailed information about the MSME.
