Class 3 Digital Signature Certificates issued in Aravind Nagar Thiruverkadu 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 Aravind Nagar Thiruverkadu 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 Aravind Nagar Thiruverkadu 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.
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.
Under the CCA Identity Verification Guidelines, a short applicant-recorded video stating name and consent is mandatory for paperless Aadhaar e-KYC issuance. It is the step most often failed when the audio is unclear or the applicant reads a different script than instructed by the Certifying Authority.

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.
A Class 3 DSC's natural validity ends on the notAfter date specified in the certificate (typically two or three years from issuance). The certificate cannot be extended in situ; instead, the subscriber must initiate a re-issuance procedure with the issuing CA at least thirty days before expiry to allow time for re-authentication and token re-flashing. Re-issuance under the CCA Identity Verification Guidelines 2018 requires the subscriber to re-authenticate via Aadhaar OTP (or the alternative pathway used at initial issuance), to confirm or update any subscriber-detail changes since the previous issuance, and to receive the new certificate either on the same physical token (which is re-flashed with the new key-pair) or on a fresh token. The old certificate is either deactivated on its natural expiry or revoked under Section 38 if the re-issuance precedes natural expiry by more than ninety days.
Where any of the subscriber's identifying details captured in the X.509 Subject Distinguished Name changes during the certificate's validity period (change of name on Aadhaar following marriage, change of organisation name following corporate rebranding, change of authorised-signatory designation following internal reorganisation), the existing certificate becomes inconsistent with the underlying subscriber record. The CCA Identity Verification Guidelines require that the subscriber initiate a change-of-particulars request with the issuing CA, leading to revocation of the existing certificate and re-issuance of a fresh certificate with the updated details. The change-of-particulars process is not free: it carries a fee equivalent to fresh issuance, since cryptographically the new certificate is a wholly new key-pair and certificate body rather than an amendment of the existing certificate.
Where the subscriber no longer requires the Class 3 DSC (retirement, change of profession, dissolution of the entity), the subscriber may surrender the certificate to the issuing CA under the Section 38 revocation framework. Surrender is in substance a revocation initiated at the subscriber's request, with no underlying compromise or wrongdoing. The CA processes the surrender, publishes the certificate serial number on the CRL and OCSP responder, and confirms the surrender to the subscriber. Surrender is good operational hygiene because it prevents an inactive certificate from being misused if the physical token falls into unauthorised hands, and it allows the subscriber to maintain a clean record at the CA for any future re-engagement. The token itself can be retained as a physical artifact or destroyed depending on the subscriber's preference.
The Reserve Bank of India's Master Direction on Digital Signing, issued in 2023 and applicable to regulated entities (banks, NBFCs, insurance companies and select fintech firms), codified the sector-specific requirements for Class 3 DSC procurement and use within the financial services sector. The Master Direction mandates Class 3 Combo certificates with FIPS 140-2 Level 2 token storage, requires the certificate's Subject Alternative Name to include the regulated entity's RBI Certificate of Registration number, prescribes a maximum certificate validity of two years (rather than the three-year general maximum) to enforce more frequent re-authentication, and requires the regulated entity to maintain a comprehensive DSC audit trail covering issuance, use, renewal and revocation events. The Master Direction also requires regulated entities to maintain a DSC-incident-response procedure aligned to the broader RBI Cybersecurity Framework.
The CCA's 2022 Cryptographic Guidelines initiated a planned migration from RSA-2048 to RSA-3072 for new subscriber certificates issued from 01-01-2025 onwards, in line with the international cryptographic-strength roadmap published by the US National Institute of Standards and Technology (NIST Special Publication 800-57) and the recommendations of the Brussels-based ENISA on post-quantum-readiness preparatory measures. The 3072-bit RSA key provides approximately 128 bits of equivalent symmetric-cryptographic strength, considered adequate against classical-computing attacks through 2030. The longer-term roadmap contemplates a migration to post-quantum cryptographic algorithms (likely the NIST-standardised CRYSTALS-Dilithium signature scheme) by 2030-2035, with the CCA expected to issue specific transition guidance closer to that timeline as the post-quantum cryptography standards mature into deployable implementations.
The CCA Office Order of 28-12-2020 mandating the discontinuance of Class 2 Digital Signature Certificate from 01-01-2021 was one of the most significant administrative interventions in the Indian DSC framework. The rationale was the structural weakness of the Class 2 identity-verification process (document-based, with low forensic strength), which had been progressively bypassed by the strengthened Class 3 verification process under the CCA Identity Verification Guidelines 2018. The transition was implemented through a phased approach: from 01-01-2021 no new Class 2 DSCs could be issued by any licensed CA, and existing Class 2 DSCs continued for the residue of their natural validity (with most having lapsed by 31-12-2023). The unification to a single Class 3 standard improved the security baseline and simplified the framework for relying parties and government portals.
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.
Every Class 3 DSC issued in India sits in a three-level certificate chain. At the apex is the CCA India 2014 root certificate (a 4096-bit RSA self-signed certificate with a 20-year validity ending in 2034) and the successor CCA India 2022 root certificate (similarly 4096-bit RSA, 20-year validity ending in 2042). Below the root is the issuing CA's intermediate certificate (typically a 2048-bit or 4096-bit RSA certificate with a 6-to-10 year validity), and at the leaf is the subscriber's certificate (2048-bit RSA, 2-or-3 year validity). The X.509 v3 standard under ITU-T Recommendation X.509 and IETF RFC 5280 governs the certificate format, with the CCA-prescribed India PKI profile imposing additional constraints on subject-naming, key-usage and extension fields to ensure interoperability with Indian government portals.
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.
