Buy Class 3 Digital Signature Certificate Online
A Class 3 Digital Signature Certificate is the highest-assurance DSC recognized by India's Controller of Certifying Authorities (CCA), and it's mandatory for GST returns, MCA/ROC filings, Income Tax e-filing, DGFT and ICEGATE transactions, EPFO submissions, and government e-Tenders. We issue it through a fully paperless Aadhaar eKYC process, so there's no physical paperwork or office visit — most certificates are ready within a few hours of verification.
What is a Class 3 Digital Signature Certificate?
A Class 3 DSC is an encrypted electronic credential, issued by a CCA-licensed Certifying Authority, that legally identifies you or your organization when signing documents online — carrying the same legal validity as a handwritten signature under the IT Act, 2000.
Why Class 3 specifically?
Class 3 is the highest assurance level issued in India. It's the only class accepted for e-tendering, e-auctions, and high-value government portal transactions, since it requires in-person or video-based identity verification before issuance.
How it's stored
Your DSC is generated inside a FIPS-140 certified USB crypto token — a small hardware key that plugs into your computer. The private key never leaves the token, which is what makes the signature legally tamper-proof.
