DSC for Company Registration: Class 2 vs Class 3, Process & Cost

Featured Answer: A Digital Signature Certificate (DSC) is mandatory for company registration in India. Every proposed director must obtain a DSC before filing the SPICe+ incorporation form on the MCA portal. Since 1 January 2021, the MCA accepts only Class 3 DSCs with a validity of two years. At Virtual Auditor, we procure DSCs for directors and authorised signatories as part of our incorporation service, ensuring zero delays in the filing process.

Definition: A Digital Signature Certificate (DSC) is an electronic equivalent of a physical signature, issued by a Certifying Authority (CA) licensed by the Controller of Certifying Authorities (CCA) under the Information Technology Act, 2000. It uses public key infrastructure (PKI) to authenticate the identity of the signer and ensure the integrity of electronically signed documents. For MCA filings, the DSC serves as the legally valid signature on incorporation forms, annual returns and other statutory documents.

Why DSC Is Mandatory for Company Registration

The Ministry of Corporate Affairs mandates electronic filing for all company incorporation and post-incorporation forms. Every form submitted on the MCA portal must be digitally signed by the proposed directors, company secretary or practising professional (CA/CS/CMA). Without a valid DSC, you cannot:

File the SPICe+ (INC-32) incorporation form
Apply for Director Identification Number (DIN)
Sign the MOA and AOA electronically
File annual returns, financial statements or charge documents
Submit forms for allotment, transfer or any corporate action

At Virtual Auditor, we have processed over a thousand DSC applications. We ensure every director’s DSC is active and linked to the correct PAN and Aadhaar details before initiating the incorporation filing.

Class 2 vs Class 3 DSC: Key Differences

Class 2 DSC

Class 2 DSCs were historically used for MCA filings, income tax e-filing, GST registration and other government portal submissions. They provided identity verification based on a pre-verified database (Aadhaar, PAN). The Certifying Authority verified the applicant’s identity against these databases before issuance.

However, effective 1 January 2021, the MCA portal transitioned to accepting only Class 3 DSCs for all filings. Class 2 DSCs are no longer valid for MCA submissions.

Class 3 DSC

Class 3 DSCs offer the highest level of assurance. They require the applicant to appear before the Certifying Authority (or undergo a video-based verification) for identity validation. Class 3 certificates are now the standard for:

All MCA filings (incorporation, annual returns, event-based forms)
e-Tendering and government procurement portals (GeM, CPPP)
Patent and trademark filings
SEBI filings and demat account operations
Customs and DGFT filings

The key differences are summarised below:

Parameter	Class 2 DSC	Class 3 DSC
Identity Verification	Database verification (Aadhaar/PAN)	In-person or video-based verification
MCA Acceptance	Not accepted since 1 Jan 2021	Mandatory for all filings
Security Level	Medium	High
Validity	1-2 years	2 years (standard) / 3 years
Use for e-Tendering	Not accepted on most portals	Accepted
Cost (Approx.)	Rs 500-800	Rs 1,000-2,500

DSC Application Process: Step by Step

Step 1 — Choose a Licensed Certifying Authority

DSCs are issued by Certifying Authorities licensed by the CCA under the IT Act, 2000. Licensed CAs in India include eMudhra, Sify, NSDL, IDRBT, Capricorn and CDAC, among others. At Virtual Auditor, we work with multiple CAs to ensure fastest turnaround.

Step 2 — Submit the Application Form

The application requires:

Full name as per PAN card
PAN number and copy of PAN card
Aadhaar number (for Indian residents)
Email address and mobile number
Passport-size photograph
Address proof (Aadhaar, passport, voter ID or driving licence)

For foreign nationals, a passport copy and address proof from the country of residence are required. The documents must be notarised or apostilled as applicable.

Step 3 — Identity Verification

For Class 3 DSC, identity verification is conducted via:

Video verification: A live video call with the Certifying Authority’s verification officer. The applicant displays original documents and answers verification questions. This is the most common method currently.
In-person verification: The applicant visits the CA’s office or an authorised partner location with original documents.
Aadhaar-based eKYC: OTP-based verification using Aadhaar-linked mobile number (available for select CAs).

Step 4 — DSC Issuance and Download

After successful verification and payment, the DSC is issued electronically. The certificate is downloaded onto a USB crypto token (hardware token) provided by the CA. The token stores the private key securely and is required every time you digitally sign a document.

Step 5 — Register DSC on MCA Portal

Once issued, the DSC must be registered on the MCA V3 portal. The director logs into the MCA portal, navigates to the DSC registration section and associates the DSC with their DIN (Director Identification Number). Without this registration, the DSC cannot be used for MCA filings.

DSC Cost in India (Current Rates)

DSC pricing varies by Certifying Authority, validity period and type of certificate:

Class 3 DSC — Signing only (2 years): Rs 1,000 to Rs 1,500
Class 3 DSC — Signing + Encryption (2 years): Rs 1,800 to Rs 2,500
Class 3 DSC — 3-year validity: Rs 2,000 to Rs 3,500
USB crypto token: Rs 300 to Rs 500 (one-time, reusable)

Our company registration packages include DSC procurement for two directors as standard. Additional DSCs are available at cost.

DSC for Foreign Directors and NRIs

Foreign nationals and NRIs who are proposed directors in an Indian company must also obtain a DSC. The process involves:

Submission of passport copy (notarised by the Indian Embassy or apostilled)
Address proof from the country of residence (utility bill, bank statement — notarised/apostilled)
Video-based verification with the Certifying Authority
PAN card is required if the foreign national has Indian-sourced income; otherwise, a passport number is used as the identifier

Processing time for foreign national DSCs is typically 3-5 working days, compared to 1-2 days for Indian residents. We coordinate the entire process, including scheduling the video verification call across time zones.

Common DSC Issues and Troubleshooting

DSC Not Recognised by MCA Portal

This typically occurs when the DSC has not been registered on the MCA V3 portal, when the Java utility (MCA signing utility or emsigner) is not installed correctly, or when the DSC has expired. Ensure the MCA signing utility is updated to the latest version and the USB token driver is properly installed.

Name Mismatch

The name on the DSC must exactly match the name on the PAN card and the DIN records. Even minor variations (middle name included vs excluded, initials vs full name) can cause rejection. We verify name consistency across all documents before initiating the DSC application.

Token Not Detected

If the USB crypto token is not detected by the computer, check the token driver installation, try a different USB port and ensure no other signing software is conflicting. The ePass2003 token (commonly issued by eMudhra) requires its specific driver.

DSC Expiry During Filing

If your DSC expires during an ongoing filing, the form cannot be submitted. We maintain a renewal tracker for all client DSCs and send reminders 30 days before expiry to ensure uninterrupted filing capability.

Expert Insight — CA V. Viswanathan: “At Virtual Auditor, we treat DSC procurement as the foundational step of company incorporation — not an afterthought. A director without an active, registered DSC cannot sign any MCA form. We have seen incorporation timelines delayed by weeks because of DSC issues that could have been resolved in advance. Our process ensures DSCs are procured, tested and registered on the MCA portal before we initiate the SPICe+ filing.”

DSC and Other Government Portals

Beyond MCA, the same Class 3 DSC can be used for:

Income Tax e-Filing: Signing returns for companies and LLPs
GST Portal: Registration application and annual return filing
DGFT: Import-Export Code (IEC) application and amendments
GeM Portal: Government e-Marketplace registration for sellers
EPFO and ESIC: Employer registration and monthly return filing
Trademark Registry: Online trademark application under the TM Act

We recommend obtaining a signing + encryption combo DSC with 2-year validity, which covers all common use cases across government portals.

Summary: A Class 3 Digital Signature Certificate is mandatory for company registration in India. Since January 2021, the MCA no longer accepts Class 2 DSCs. The application process involves submitting identity documents, undergoing video or in-person verification by a licensed Certifying Authority and downloading the certificate onto a USB crypto token. Cost ranges from Rs 1,000 to Rs 2,500 for a 2-year certificate. The DSC must be registered on the MCA portal before it can be used for filing. Virtual Auditor handles DSC procurement end-to-end as part of our company registration service.

Frequently Asked Questions

Is a DSC mandatory for all directors of a company?

Yes. Every director who signs any MCA form must have a valid Class 3 DSC. At the time of incorporation, at least the proposed directors who are subscribers to the MOA need DSCs. Post-incorporation, any director signing annual returns, board resolutions or event-based forms also requires a DSC.

How long does it take to get a DSC?

For Indian residents, a Class 3 DSC is typically issued within 1-2 working days after document submission and video verification. For foreign nationals, the processing time is 3-5 working days due to additional document verification requirements.

Can I use one DSC for multiple purposes (MCA, GST, Income Tax)?

Yes. A Class 3 DSC with signing capability can be used across all government portals that accept digital signatures — MCA, Income Tax, GST, DGFT, GeM and others. You do not need separate DSCs for each portal. However, you must register the DSC separately on each portal where you intend to use it.

What happens if my DSC expires?

An expired DSC cannot be used for any filing. You must apply for a new DSC (renewal is essentially a fresh issuance with the same details). There is no grace period — the DSC becomes invalid on the date of expiry. We recommend initiating renewal at least 15-30 days before expiry.

Can a DSC be revoked?

Yes. A DSC can be revoked by the Certifying Authority if the private key is compromised, the subscriber’s details change, or the subscriber requests revocation. Revoked certificates are published in the Certificate Revocation List (CRL). Once revoked, a new DSC must be obtained.

Is a physical USB token always required?

For MCA filings, yes — the DSC must be stored on a USB crypto token. Some Certifying Authorities now offer cloud-based DSC (paperless DSC) for certain use cases like GST and Income Tax, but the MCA portal currently requires a hardware token-based DSC for form signing.

What is the difference between a signing DSC and an encryption DSC?

A signing DSC is used to digitally sign documents and forms — this is what you need for MCA filings. An encryption DSC is used to encrypt and decrypt data — useful for secure email communication and tender submissions. For company registration, a signing DSC is sufficient. For e-tendering, both signing and encryption are typically required.
