Class 3 Digital Signature Certificates issued in Nerkundram-Mogappair Road under Section 35 of the IT Act 2000 by CCA-licensed Certifying Authorities — paperless Aadhaar OTP e-KYC, FIPS 140-2 USB token and 2-year standard validity. Class 2 DSC deprecated 1-Jan-2021.
Class 3 individual DSC for Nerkundram-Mogappair Road directors, partners and proprietors — used for MCA DIR-3 KYC, SPICe+ incorporation, Income Tax ITR signing under Section 140 of the Income-tax Act and personal e-Tendering. Same-day Aadhaar e-KYC issuance.
Class 3 organisation DSC for Nerkundram-Mogappair Road companies and LLPs — used for GST authorised signatory under Rule 26 CGST Rules, TRACES Form 24Q/26Q TDS filing under Section 200(3) Income-tax Act, IceGate Customs and DGFT IEC. Authorisation letter and CIN/GSTIN proof required.
CCA Identity Verification Guidelines 2021 permit three modes — paperless Aadhaar OTP e-KYC, video-based verification with original document display, and in-person verification before a CA-authorised officer. Choice depends on Aadhaar mobile linkage and applicant location.
A Class 3 signature DSC costs approximately ₹1,200–₹1,500 one-time for a 2-year certificate including the FIPS 140-2 Level 2 USB token, Aadhaar e-KYC and video verification. A combo (sign + encrypt) DSC costs approximately ₹1,800–₹2,500 for the same term.
Class 3 DSCs are issued for 1, 2 or 3 years. A 2-year term is the common choice — it balances cost against re-verification effort. The certificate cannot be extended; a fresh e-KYC is required at renewal, so renew a few days before expiry to avoid a filing block.
Yes. A single Class 3 signature DSC works across MCA21 V3, GST, Income-tax, TRACES, EPFO, ICEGATE and DGFT once registered on each portal. It must be registered under the correct role on each site — for example mapped to the authorised signatory on the GST portal under Rule 26.
The certificate on a lost or corrupted FIPS token cannot be recovered — the private key never leaves the device by design. You must apply for a fresh certificate with new e-KYC and re-register it on every portal. Report misuse risk to the issuing Certifying Authority for revocation.
Yes. A foreign national or NRI can obtain a Class 3 DSC using an apostilled or consular-attested passport and address proof, with video verification. Indian PAN is required where the DSC is used for MCA or Income-tax filings; DIN-linked director DSCs additionally need the PAN or passport on record with the MCA.
Yes. Simply holding the token is not enough — each portal requires a one-time registration mapping the DSC to your PAN or DIN and role. On MCA21 V3 the director registers the DSC against the DIN; on GST the authorised signatory registers it against the GSTIN before any DSC-signed filing is accepted.

A Digital Signature Certificate (DSC) is an electronic credential issued by a licensed Certifying Authority (CA) that binds a public-key cryptographic key-pair to the identity of a subscriber, enabling the subscriber to digitally sign electronic records with legal effect equivalent to a handwritten signature. The Indian framework is established under the Information Technology Act 2000, which received Presidential assent on 09-06-2000 and was inspired by the UNCITRAL Model Law on Electronic Commerce 1996 adopted by the United Nations Commission on International Trade Law in resolution 51/162 of 16-12-1996. Sections 35 to 39 of the IT Act 2000 set out the framework for issuance, suspension and revocation of Digital Signature Certificates, while Section 17 establishes the office of the Controller of Certifying Authorities (CCA) as the apex regulator of the DSC ecosystem in India.
Historically, DSCs were issued in three classes — Class 1, Class 2 and Class 3 — corresponding to progressively higher levels of identity verification. Class 1 was issued on the basis of an email-address verification alone and was suitable for low-value transactions. Class 2 was issued on the basis of identity-document and address-document verification and was the workhorse certificate for income-tax e-filing, MCA21 and most government portals for over a decade. Class 3 has historically required in-person verification or video-verification with biometric authentication and was reserved for high-value transactions such as e-tendering and e-procurement. The CCA's Office Order of 28-12-2020 mandated the discontinuance of Class 2 DSC from 01-01-2021, leaving Class 3 as the single class of DSC for all use-cases. The transition was completed by mid-2021 with the entire ecosystem migrated to Class 3 by issuing CAs.
The IT (Amendment) Act 2008, which came into force on 27-10-2009, inserted Section 3A in the IT Act 2000 to recognise a broader category of electronic signature in addition to the Digital Signature Certificate based on asymmetric cryptography. Section 3A enables the Central Government to notify by rule any electronic signature technique that is reliable as defined in the section. The notification under Section 3A enabled the Aadhaar-based e-Sign service launched in 2015, under which a subscriber authenticates via Aadhaar OTP or biometric and a one-time certificate is issued for the immediate signing transaction. Class 3 DSC and e-Sign coexist as alternative authentication mechanisms, with Class 3 DSC being the preferred mode for multi-use and high-value transactions and e-Sign being the preferred mode for single-transaction citizen-facing workflows.
Each licensed CA is required under Section 30 of the IT Act 2000 to publish a Certification Practice Statement (CPS) setting out its operational practices for identity verification, certificate issuance, suspension and revocation. The CPS is reviewed and approved by the CCA at the time of licensing and during periodic compliance audits. From 2018 onwards, the CCA aligned the India CPS framework with the European Telecommunications Standards Institute (ETSI) standard EN 319 411-1 and EN 319 411-2, which prescribe baseline policy requirements for trust service providers issuing certificates for electronic signatures. The alignment was driven by the goal of facilitating mutual recognition of Indian DSCs in international transactions and by the recommendation in the WTO Trade Facilitation Agreement on harmonisation of cross-border e-document standards.
Section 17 of the IT Act 2000 establishes the office of the Controller of Certifying Authorities (CCA), appointed by the Central Government, with responsibility for licensing and supervising the Certifying Authorities that issue Digital Signature Certificates in India. The CCA functions as the Root Certifying Authority of India (RCAI) and issues the trust-anchor certificates from which all licensed CAs derive their own intermediate certificates. The CCA's regulatory functions include issuance of licences to CAs under Section 21, approval of Certification Practice Statements (CPS), supervision of CA operations through periodic audits, suspension or revocation of CA licences under Section 25, and maintenance of the National Repository of Digital Signature Certificates under Section 20.
As of 2026, seven Certifying Authorities operate under CCA licence to issue Class 3 DSCs in India: eMudhra Limited (the largest by issuance volume), Sify Safescrypt (the oldest licensed CA, in operation since 2002), NCode Solutions (a unit of the National Informatics Centre, operated under the Ministry of Electronics and IT), Capricorn Identity Services, Verasys Technologies, ProDigital Signatures, and IDsign (a recent entrant licensed in 2023). Two additional CAs — IDRBT Certifying Authority and TCS-CA — have legacy licences but are oriented towards specific sectoral use-cases (banking and Tata-group entities respectively). Each CA operates its own subscriber-onboarding infrastructure, fee schedule and value-added services, but all are bound by uniform CCA-prescribed standards on certificate format, key-usage and revocation processes.
Video-based verification was introduced by the CCA in 2018 as an interim pathway following the Supreme Court's interim observations in K.S. Puttaswamy v. Union of India on Aadhaar use by private entities. Under VBV, the subscriber participates in a real-time video call with a trained verifier at the CA's verification centre, presents identity and address documents to the camera, and reads aloud a randomly-generated text-string to demonstrate liveness. The video session is recorded and retained as part of the subscriber-onboarding file. The VBV pathway remains available and is the preferred fall-back for subscribers who face Aadhaar-OTP issues (such as mobile-number-update mismatches) or who require expedited issuance outside normal CA working hours. The Capricorn-WD-NCode federation operates an extended-hours VBV centre that serves urgent professional and corporate requirements.
Issuance of a Class 3 Organisation DSC (where the subscriber is a company, LLP, partnership firm or other legal entity, with an authorised signatory acting on its behalf) requires additional verification steps beyond the individual signatory's identity. The CA must verify the entity's incorporation (certificate of incorporation for company, LLP agreement for LLP, partnership deed for firm, trust deed for trust) and the resolution or other document authorising the named signatory to obtain a DSC in the entity's name. For companies, a board resolution under Section 179 of the Companies Act 2013 and certified copies of MOA, AOA and CoI are the standard supporting documents. For LLPs, a designated partners' resolution and the LLP agreement are required. The Organisation Unit field on the X.509 Subject DN captures the entity's CIN or LLPIN as a mandatory data element.
The CCA Identity Verification Guidelines 2018 (revised 2022) prescribe a tiered identity-verification process for issuance of Class 3 DSC. The primary pathway is Aadhaar-based e-KYC, where the subscriber authenticates through an OTP sent to the mobile number registered with the UIDAI database against the subscriber's Aadhaar number, or alternatively through biometric authentication at a CA-empanelled biometric station. The e-KYC pathway leverages the Aadhaar (Targeted Delivery of Financial and Other Subsidies, Benefits and Services) Act 2016, specifically Section 8 read with the Aadhaar (Authentication) Regulations 2016, and produces a verified subscriber-record that is digitally signed by UIDAI for inclusion in the CA's subscriber-onboarding file. The Aadhaar pathway is the dominant route, accounting for over ninety per cent of Class 3 DSC issuance in 2025.
A Class 3 Encryption certificate carries a key-usage extension limited to keyEncipherment and dataEncipherment, and is designed for the use-case where the subscriber needs to receive confidential documents encrypted with their public key. The private key is used to decrypt incoming messages, and the public key is published in the CA's directory for senders to use as the encryption target. Encryption-only certificates are less common in standalone form because most subscribers also need signing capability, but they are required as a distinct credential in certain e-tendering workflows where the procuring entity encrypts the technical-bid documents to the bidder's public key for confidentiality during the pre-opening window. The corresponding cryptographic algorithm under the India PKI profile is RSA with PKCS#1 v1.5 or OAEP padding.
A Class 3 Combo certificate combines both signing and encryption capabilities in a single token, often through two physically-separate certificate-and-key-pairs stored on the same hardware token. Combo certificates are required for use-cases that involve both signing and confidentiality — notably e-tendering on CPPP, GeM, IREPS and several state e-procurement portals where the bidder signs the bid document with the signing certificate and the procuring entity encrypts feedback to the bidder using the encryption certificate. The ONDC seller-node TLS-mutual-authentication architecture similarly requires a Combo certificate. Combo certificates carry a higher unit cost than signing-only or encryption-only, but the practical convenience of a single token covering both use-cases drives most corporate procurement towards Combo.
A Document Signer Certificate is a specialised variant of the Class 3 Organisation DSC, introduced by the CCA in 2017 to enable unattended bulk signing in enterprise workflows (digital invoice signing under the GST e-invoice framework, bulk certificate issuance by educational institutions, contract-signing automation in financial services). The Document Signer Certificate is issued in the name of the legal entity (not an individual signatory) and is stored on a Hardware Security Module (HSM) compliant with FIPS 140-2 Level 3 or equivalent, rather than on a USB cryptographic token. The HSM-based storage allows the certificate to be invoked programmatically without manual PIN entry, supporting high-volume signing throughput. The CCA's 2017 office order specifying this variant requires additional CA-level controls including HSM audit logging and segregation of duties between the certificate-administration team and the signing-operation team.

“Needed Class 3 individual DSC for incorporating a private limited company. FilingPro completed the Aadhaar OTP e-KYC over WhatsApp and the DSC was loaded onto the ePass2003 token within 45 minutes. Used it the same evening for SPICe+ filing on MCA21. Smooth and paperless.”
“Required organisation DSC for our GST authorised signatory. FilingPro drafted the board resolution and authorisation letter, coordinated with the CA for video KYC and we received the DSC the next morning. Replaced our older Class 2 DSC which had expired post-Jan-2021 deprecation.”
“Multi-director DSC pack for our 5-director board needed for SPICe+ and tender bidding. FilingPro coordinated all 5 Aadhaar e-KYCs in one day, supplied premium Watchdata tokens with encryption-signing pair and we were tender-ready by next working day. The premium pack saved significant time.”
“My USB token got locked after multiple wrong PIN attempts. FilingPro explained that the certificate had to be re-issued — the private key on the token cannot be recovered. They processed a fresh Aadhaar e-KYC the same day and a new 2-year DSC was loaded. Clear technical explanation, no nonsense.”
“Needed Class 3 DSC urgently for TRACES TDS return filing — last day of the quarter. FilingPro arranged Aadhaar OTP e-KYC within an hour, the DSC was issued same-day and we filed Form 24Q before midnight. Saved us a Section 234E late fee. Excellent crisis response.”
“Renewed our company's organisation DSC after 2-year expiry. FilingPro reused the existing authorisation letter and entity documentation, only fresh signatory Aadhaar e-KYC was needed, and the new DSC came through in half a day. Smooth renewal cycle, no surprises on documentation.”
