Class 3 Digital Signature Certificates issued in Ambattur Red Hills 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 Ambattur Red Hills 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 Ambattur Red Hills 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 DSC is a digital signature certificate issued under Section 35 of the IT Act 2000. After the CCA discontinued Class 2 certificates from 1 January 2021, Class 3 — with in-person or video identity verification — became the sole class issued for all statutory and commercial filings.
Yes. MCA21 V3 accepts only Class 3 DSCs for director and professional filings, and the GST portal requires a Class 3 DSC for companies and LLPs under Rule 26 of the CGST Rules 2017. Individuals and proprietors may use EVC, but a DSC is still required for many forms.
A signature DSC only signs documents for authentication and non-repudiation. A combo DSC adds a separate encryption certificate to decrypt data returned by a portal — needed mainly for government e-tenders (GeM, CPPP) and IP India trademark filings. Most tax filers need only the signature type.
With Aadhaar-based paperless e-KYC and video verification, a Class 3 DSC is typically issued the same working day. Delays arise only when the mobile number is not linked to Aadhaar or the applicant's name mismatches between PAN and Aadhaar.
For Aadhaar e-KYC: PAN, Aadhaar-linked mobile for OTP, a passport-size photo and a short video verification. For paper-based KYC: self-attested PAN and address proof attested by a gazetted officer or banker. The applicant's mobile and email must be their own.
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.

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.
Section 5 of the IT Act 2000 provides that where any law requires that a document be signed, the requirement is satisfied if the document is authenticated by means of a Digital Signature affixed in such manner as may be prescribed. Section 85B of the Indian Evidence Act 1872 (inserted by the IT Act 2000 and renumbered by the Bharatiya Sakshya Adhiniyam 2023) creates a presumption that a secure electronic record has not been altered since the date on which the digital signature was affixed. Section 67A of the Bharatiya Sakshya Adhiniyam 2023 (corresponding to the earlier Section 67A of the Evidence Act) requires that a person seeking to rely on an electronic record produce a certificate from the CA verifying the signature. Together, these provisions establish digital signatures as functionally equivalent to handwritten signatures for evidentiary purposes in Indian courts.
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.
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 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.
The launch of MCA21 v3 in 2023 (rolled out in phases beginning January 2023 and completed across all form-categories by mid-2024) brought with it a significant strengthening of the signature-validation logic. The v3 platform replaced the daily-CRL-cache architecture of v2 with real-time OCSP queries for revocation status, replaced the PKCS#7 attached-signature format with the more compact detached-signature format, introduced Subject DN-to-MCA-record reconciliation at the form-validation stage (so that a signature mismatch is flagged immediately rather than at the post-filing review stage), and tightened the supported-CA list to remove certain legacy intermediate certificates. The cumulative effect was to make MCA21 v3 the most signature-stringent of the major Indian government portals, and the platform on which DSC environment-validation matters most.
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.
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.

“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.”
