Understanding Class 3 Digital Signature Certificate (DSC)
In today’s digital-first world, businesses and professionals must adapt to new technologies to remain competitive and compliant. One such critical tool is the Class 3 Digital Signature Certificate (DSC), which plays an essential role in securing online transactions, government filings, and business registrations.
If you're a business owner, freelancer, CA, CS, or legal professional looking to participate in e-tenders, file GST returns, register a trademark, or incorporate a company, then this guide will walk you through everything you need to know about Class 3 DSC—and how PantaSign makes it easy and affordable.

What is a Digital Signature Certificate?
A Digital Signature Certificate (DSC) is a secure digital key that certifies the identity of an individual or organization participating in electronic transactions. It serves as the digital equivalent of physical documents like a passport or driver’s license.
Different Classes of DSC
- Class 1: Verifies only the email address and name of the user.
- Class 2: Used for filing documents with MCA, Income Tax Department, etc.
- Class 3: Highest level of security; used for e-tendering, e-procurement, and other high-risk applications.
What is Class 3 DSC?
The Class 3 Digital Signature Certificate is issued after verifying the applicant’s identity in person by a licensed Certifying Authority (CA). It is used for high-security applications where data integrity and authenticity are crucial.
Unlike Class 1 and Class 2 DSCs, Class 3 requires face-to-face verification—either physically at a Registration Authority (RA) center or through video verification—to ensure maximum reliability.
