A DSC is primarily used for:
- e-Tendering and e-Procurement
- Income Tax and GST filings
- Company Incorporation (MCA e-filing)
- Signing legal contracts and documents
- Online submissions in government portals
Depending on your purpose, you can opt for Class 3 Digital Signature Certificates, which are now widely used for both individual and organizational authentication.
