About the Certificate of Incorporation
The COI is issued electronically by the MCA upon successful processing of the SPICe+ (or FiLLiP for LLP) application. It contains the Company Identification Number (CIN), the date of incorporation, the registered name, and the registered office state. The COI is the definitive proof of the company's legal existence.
Along with the COI, the MCA simultaneously issues the company's PAN (e-PAN) and TAN (e-TAN), and sends confirmation of EPFO and ESIC registration. You do not need to apply for these separately.
