Buy Class 3 DSC Online refers to obtaining a Class 3 Digital Signature Certificate, the highest-assurance DSC category, commonly required as MCA digital signature for company filings and e-tendering.
Most founders discover they need to buy Class 3 DSC online the first time an accountant asks, only to find verification steps take longer without guidance.
Digital signing for GST filing has become increasingly common as processes move toward mandatory digital signatures.
MCA-related requirements are stricter than most people expect — the certificate must be registered against the specific director's DIN on the MCA portal before it can actually be used to sign incorporation, annual filing, or other statutory forms, a linking step that's separate from simply purchasing the DSC itself.
bizOversal handles both the DSC issuance and the MCA portal registration together, since a certificate never linked to the director's DIN is functionally useless for actual filings despite being technically valid.

No, identity verification is done via video call, and the certificate is issued on a USB token delivered to you without needing an in-person office visit.
Not for every taxpayer, but it's increasingly required for companies and LLPs where an authorized signatory's DSC is needed rather than simple OTP-based verification.

Either 2 or 3 years depending on which validity period you choose at purchase, after which it needs to be renewed.
