The type of applicant and the purpose for which the Digital Signature Certificate is obtained defines the kind of DSC one must apply for depending on the need. There are three types of Digital Signature certificates issued by the certifying authorities.
Class 1 Certificates: These are issued to individual/private subscribers and are used to confirm that the user’s name and email contact details from the clearly defined subject lie within the database of the certifying authority.
Class 2 Certificates: These are issued to the director/signatory authorities of the companies for the purpose of e-filing with the Registrar of Companies (ROC). Class 2 certificate is mandatory for individuals who have to sign manual documents while filing returns with the ROC. However, from 01.01.2021, the Controller of Certifying Authority has instructed to discontinue Class 2 Certificates and Class 3 Certificates will be issued in place of Class 2 Certificates.
Class 3 Certificates: These certificates are used in online participation/bidding in e-auctions and online tenders anywhere in India. The vendors who wish to participate in the online tenders must have a Class 3 digital signature certificate.
