Class 3 Digital Signature Certificates issued in Kovur Porur 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 Kovur Porur 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 Kovur Porur 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.
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.
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.

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.
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.
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.
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.
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.
For subscribers who cannot or choose not to authenticate via Aadhaar, the CCA Identity Verification Guidelines permit alternate pathways. PAN-based verification leverages the Income Tax Department's PAN database, with the subscriber submitting a self-attested PAN copy and the CA verifying the PAN-name-DOB triplet against the IT Department's verification API. Document-based verification, the legacy pathway from the pre-Aadhaar era, requires the subscriber to submit self-attested copies of identity proof (passport, voter ID or driving licence) and address proof (utility bill, bank statement or rent agreement), with attestation by a Bank Manager, Gazetted Officer, Post Master or Notary as the case may be. Document-based verification is permitted for non-resident Indian subscribers and for Indian-resident subscribers in exceptional cases where Aadhaar and PAN authentication are unavailable.
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.
