A plain-language look at DSC classes, what each is used for, and why Class 3 is the one most people need today.
A Digital Signature Certificate (DSC) is the electronic equivalent of a handwritten signature or a physical seal — it's used to sign documents and forms online in a way that's legally recognised and tamper-evident. If you're filing GST returns, submitting an e-tender, or signing MCA forms, you'll be asked for one.
DSCs used to be issued in different classes based on the level of identity verification involved. As per current Controller of Certifying Authorities (CCA) guidelines, Class 2 certificates have been phased out — Class 3 is now the standard for individuals and organisations across most use cases, including MCA filings, income tax e-filing and GST.
Class 3 involves stronger identity verification (including video verification in most cases) and is mandatory for e-tendering and e-auctions, where the certifying authority needs a higher assurance level before letting you bid.
