Every DSC question we hear, answered without jargon

A DSC is an electronic credential issued under the Information Technology Act, 2000 by Certifying Authorities licensed by the Controller of Certifying Authorities (CCA), Ministry of Electronics & IT. It lets you sign electronic documents and government filings in a way that proves who signed and that nothing was altered afterwards — the digital equivalent of a handwritten signature, with stronger evidence behind it. Our DSC services overview covers what we issue and for whom.

The CCA directed that issuance of Class 2 certificates be withdrawn from 1 January 2021, and since then every new applicant receives Class 3, the highest assurance level. Older portal help pages still mention Class 2 because previously issued certificates remained usable until they expired. If you are buying today, Class 3 is the only choice — and the only one you need.

An individual DSC is issued in your own name and is what directors, proprietors, professionals and taxpayers use for GST, MCA and income tax work. An organisation DSC is issued to a person as an authorised signatory of an organisation, with the organisation's name inside the certificate — the form generally required or preferred for e-tenders, DGFT filings by non-proprietor entities, and ICEGATE.

A signature certificate signs documents and filings — that is what MCA, GST and income tax need. An encryption certificate encrypts data, such as bid documents on e-procurement portals. A combo is the pair together, and it is the standard purchase for e-tendering, where bids must be both signed and encrypted — see the tender DSC page for how this plays out in practice.

No. Aadhaar eSign is a one-time online signature made through Aadhaar authentication, useful where portals accept it. A DSC is a certificate you hold on a hardware token, valid for one to three years, and it is the mode certain filings require — companies and LLPs on GST, MCA filings, tender bids. Our knowledge article on DSC vs eSign compares them properly.

You share your Aadhaar number, receive an OTP on your Aadhaar-linked mobile, and the CA fetches your verified identity electronically — no forms, no photocopies. Aadhaar biometric and offline-Aadhaar variants also exist, along with PAN-based and banking eKYC for applicants who cannot use Aadhaar OTP. It is the fastest route to issuance by a wide margin.

A short, live, interactive video recorded through the CA's system — uploaded clips are not accepted. You appear on camera for at least 20 seconds with your face filling around half the frame and read out random codes shown to you. It typically takes a few minutes, and the certificate must then be issued within two days of a successful video. Our video verification guide walks through it with screenshots-level detail.

For an individual on the paperless Aadhaar-OTP route, typically within 24 hours of completing verification — often faster. Organisation certificates typically take one to three working days because the organisational documents are checked manually by the CA. These are typical times, not promises; the CA's workload sets the actual pace.

No. The entire process — application, eKYC, OTPs, video verification — happens on your phone from anywhere in India, with us guiding on WhatsApp. The token is handed over at our Vadodara office or dispatched to you, and setup support is remote or walk-in, whichever suits. Plenty of clients we have never met in person sign every month.

Yes. The CCA's identity verification guidelines permit PAN-based eKYC with document upload, banking eKYC through your bank record, and CA-assisted verification for cases such as foreign applicants. These routes involve a little more paperwork than Aadhaar OTP and can take longer, but they end in the same Class 3 certificate. Video and OTP verification still apply.

Log in and go to Services → User Services → Register/Update DSC, with the emSigner utility running and your token plugged in. One strict rule: only the person whose PAN appears in the GST registration can register the DSC, so the certificate must be in that person's name. DSC signing is the required mode for companies and LLPs — the GST DSC page has the full walkthrough.

On MCA V3, the certificate is associated through the Register DSC service under your profile, using the MCA DSC utility — directors register against their DIN, practising professionals against their membership number, and others with PAN. Until this association is done, the portal will not accept your signature on forms. Details on the MCA DSC page.

Companies must sign their returns with a DSC, as must persons whose accounts are subject to tax audit; others can generally use EVC or Aadhaar-based verification. The certificate is registered on the e-filing portal under My Profile → Register DSC, with the signing utility and token drivers in place. The income tax DSC page covers who needs one and how registration works.

E-procurement portals typically require a Class 3 organisation certificate as a signature-plus-encryption combo, since bids are encrypted as well as signed — see the tender DSC page. DGFT needs a Class 3 certificate registered against your IEC, with the certificate matching the proprietor's PAN or the organisation name in the IEC profile — details on the DGFT DSC page. ICEGATE requires Class 3 for customs filings; the ICEGATE DSC page explains who needs it. Requirements vary by portal, so confirm the target portal's rules before buying.
