MSME (Micro, Small and Medium Enterprises) re-registration https://msme-registration.in/msme-re-registration-online-apply.php is a process of updating and validating the information of an existing MSME. It is mandatory for businesses registered under the MSME Act 2006 to re-register every 5 years. The process can be done online through the Udyam Registration portal using the existing Udyog Aadhaar Number (UAN) or the PAN card of the business owner. Once re-registered, the MSME can continue to avail the benefits and incentives provided by the government for MSMEs.
