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

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.
The Certificate Revocation List is a digitally-signed list of revoked certificate serial numbers published periodically (typically every twenty-four hours) by each issuing CA at a URL specified in the CRL Distribution Points extension of every subscriber certificate. The CRL format and update mechanics are governed by IETF RFC 5280. The Online Certificate Status Protocol (OCSP), specified in IETF RFC 6960, provides a real-time alternative to CRL: a verifier sends an OCSP query to the issuing CA's OCSP responder with a specific certificate serial number and receives an immediate signed response confirming the certificate's status as good, revoked or unknown. The India PKI profile requires every Class 3 DSC to carry both a CRL Distribution Points extension and an Authority Information Access extension pointing to the OCSP responder URL, enabling verifiers to choose the appropriate revocation-check mechanism for their workflow.
Section 37 of the IT Act 2000 provides for suspension of a Digital Signature Certificate as a temporary measure short of revocation. Suspension may be invoked by the CA on its own motion or on a request from the subscriber or any person authorised by the subscriber, where the circumstances warrant a temporary halt of the certificate's operational validity pending resolution of an issue (suspected compromise that is being investigated, dispute over the subscriber agreement, or processing of a change-of-particulars request). The suspended certificate appears on the CRL with a status of certificateHold and a specific OCSP response indicating suspension. If the underlying issue is resolved, the suspension may be lifted and the certificate restored to operational status. If the issue cannot be resolved, the suspension typically converts to a full revocation under Section 38.
Where the subscriber has reason to believe that the private key associated with the Class 3 DSC has been compromised (lost token, stolen token, suspected malware on the host machine, or exposure of the token PIN to an unauthorised person), the subscriber must immediately initiate revocation under Section 38 and notify the issuing CA. Most issuing CAs offer a twenty-four-hour helpline for emergency revocation initiation. The compromised-key protocol involves: (a) immediate revocation request on the CA's portal or helpline, (b) the CA's publication of the revoked serial number on the CRL and OCSP responder within twenty-four hours (typically much faster), (c) the subscriber's review of all documents signed during the compromise window to identify any unauthorised signings, and (d) procurement of a fresh certificate to restore signing capability.
The European Union's electronic identification and trust services framework is established under Regulation (EU) 910/2014 of the European Parliament and of the Council of 23-07-2014 on electronic identification and trust services for electronic transactions in the internal market, commonly referred to as the eIDAS Regulation. eIDAS establishes a three-tier taxonomy of electronic signatures: Electronic Signature (the lowest tier, broadly equivalent to any electronic data attached to an electronic record), Advanced Electronic Signature (AES, which uniquely identifies the signatory and is linked to the signed data such that any subsequent change is detectable), and Qualified Electronic Signature (QES, an AES created by a qualified signature creation device and based on a qualified certificate). Under Article 25 of eIDAS, a QES has the equivalent legal effect of a handwritten signature throughout the European Union. The Indian Class 3 DSC corresponds taxonomically to AES under eIDAS, not QES.
In the United States, electronic signatures are governed at the federal level by the Electronic Signatures in Global and National Commerce Act (ESIGN Act) of 2000, which establishes the general rule that a signature, contract or record relating to a transaction in or affecting interstate or foreign commerce shall not be denied legal effect, validity or enforceability solely because it is in electronic form or because an electronic signature was used in its formation. The ESIGN Act is supplemented at the state level by the Uniform Electronic Transactions Act (UETA), adopted in 1999 by the Uniform Law Commission and enacted in some form by forty-seven of the fifty states (with New York, Illinois and Washington having parallel state legislation). The US framework is technology-neutral and does not impose a specific cryptographic standard, making it easier than eIDAS for an India Class 3 DSC to be accepted in US commercial transactions on a reliability-based assessment.
Singapore's Electronic Transactions Act 2010 (which replaced the earlier ETA 1998) is one of the most cleanly-drafted electronic-transactions statutes in the Asia-Pacific region and adopts the UNCITRAL Model Law on Electronic Commerce 1996 and the UNCITRAL Model Law on Electronic Signatures 2001 substantially verbatim. The ETA 2010 establishes a Secure Electronic Signature standard analogous to the AES under eIDAS, and provides for mutual recognition of foreign electronic signatures under Section 8 where the foreign signature is shown to be reliable. The Section 8 reliability assessment looks at factors including the sophistication of the equipment, the nature of the transaction, the parties' course of dealing and any consent provided. India Class 3 DSCs are routinely accepted in Singapore-governed commercial transactions under this Section 8 reliability framework.
The Goods and Services Tax Network (GSTN) portal accepts Class 3 DSC for authentication of registration applications (REG-01, REG-14), return filings (GSTR-1, GSTR-3B, GSTR-9, GSTR-9C), refund claims (RFD-01) and the various notice-reply workflows. For companies and LLPs, Class 3 DSC is mandatory; for other entity types (proprietorships, HUF), Aadhaar-based e-Sign is permitted as an alternative. The GST e-invoice framework introduced under Notification 13/2020-Central Tax and operationalised from 01-10-2020 requires invoices generated by notified taxpayers to be digitally signed by the Invoice Registration Portal (IRP) using its own Class 3 Document Signer Certificate before the signed JSON is returned to the taxpayer with an Invoice Reference Number (IRN). The architecture preserves the taxpayer's option to also affix their own Class 3 DSC on the underlying invoice for additional evidentiary weight.
The Income Tax Department's e-filing portal accepts Class 3 DSC for filing ITR-5 (LLPs and firms), ITR-6 (companies) and ITR-7 (trusts and societies), where DSC authentication is mandatory; for individual returns and HUF returns, Aadhaar-based e-Sign and Electronic Verification Code (EVC) are permitted alternatives. The Department's internal Income Tax Business Application (ITBA) accepts Class 3 DSC from authorised representatives and chartered accountants in proceedings under Section 144B (faceless assessment), Section 250 (faceless appeal) and Section 274 (faceless penalty), where the authorised representative's professional DSC carries evidentiary weight against the assessing officer's digitally-signed assessment order. The 2024-25 transition to fully electronic assessment proceedings has accelerated the need for chartered accountants and lawyers to maintain valid Class 3 DSCs as a professional-practice requirement.
The Central Public Procurement Portal (CPPP) at eprocure.gov.in, the Government e-Marketplace (GeM) and the Indian Railways e-Procurement System (IREPS) collectively constitute the central-government e-procurement ecosystem, with annual procurement throughput exceeding ₹10 lakh crore. Each of these portals mandates Class 3 DSC authentication for bidder registration, bid submission and contract execution. The technical-bid documents on CPPP are encrypted with the procuring entity's public key (a Combo certificate) and the bidder's digital signature is affixed using the bidder's signing private key; the bid is opened only after the prescribed opening time, with the procuring officer's decryption private key used to access the technical-bid documents. This dual-cryptographic architecture is the principal reason why Combo (Signing plus Encryption) Class 3 DSCs are required for any meaningful participation in central e-procurement.

“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.”
