Class 3 Digital Signature Certificates issued in Ambattur Korattur 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 Korattur 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 Korattur 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.
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.

Reading this guide locally — Across Ambattur Korattur Road, in the industrial commercial corridor micro-market of Ambattur Korattur Road.
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.
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.
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.
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.
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.
A Class 3 Signing certificate carries a key-usage extension limited to digitalSignature and nonRepudiation under RFC 5280, and is designed for the use-case where the subscriber needs to authenticate documents and electronic records by affixing a digital signature. The certificate's private key is used to compute the signature over a cryptographic hash of the document, and the public key (carried in the certificate itself) is used by the verifier to confirm authenticity and integrity. Signing-only certificates are sufficient for most government-portal use-cases including MCA21, GST, EPFO, ESIC, ICEGATE, and DGFT. They are typically the cheapest variant offered by issuing CAs, with one-year, two-year and three-year validity SKUs, and are the default recommendation for individual subscribers and small enterprises.
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.

“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.”
