A Class-3 DSC is a highly secure electronic signature used for online transactions requiring a high level of trust and authentication. It verifies the signer’s identity and ensures document integrity.

Individuals and organizations can obtain a Class-3 DSC. However, it requires a more stringent physical verification process compared to lower classes of DSCs.

For individuals, this usually includes identity proof, address proof, and a photograph. For organizations, it involves organizational identity and address proof, along with details and authorization of the signatory.

The process involves choosing a Certifying Authority, submitting an application with required documents, undergoing a mandatory physical (or video) verification, and receiving the DSC on a USB token upon successful verification.

Class-3 DSCs are widely used for secure online transactions such as MCA filings, GST returns, Income Tax e-filing, e-tendering, and other platforms where high security and legal validity are essential.
