Class 3 Digital Signature Certificates issued in Madhavaram Milk Colony 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 Madhavaram Milk Colony 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 Madhavaram Milk Colony 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.
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.
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.

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 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.
Class 3 DSC and Aadhaar-based e-Sign are both recognised under the IT Act 2000 framework (DSC under Sections 35-39 and Schedule II, e-Sign under Section 3A inserted by the IT (Amendment) Act 2008 and the Rules thereunder) but differ materially in their operating characteristics. A Class 3 DSC is a multi-use credential with a validity of one, two or three years (two years being the most common), allowing the subscriber to use the same certificate for an unlimited number of signing transactions during the validity period. An e-Sign certificate is a single-transaction credential with a validity of approximately thirty minutes, issued just-in-time for a specific signing event and rendered inoperative once the transaction is complete. The reusability difference makes DSC the preferred choice for high-frequency signers and e-Sign the preferred choice for occasional consumer-facing transactions.
Class 3 DSC requires a FIPS 140-2 Level 2 hardware cryptographic token to store the private key, with the token costing approximately ₹500 to ₹1500 in addition to the certificate fee. The token must be physically present at the signing workstation and the user must enter the token PIN to authorise each signing operation, providing a strong two-factor (something-you-have plus something-you-know) authentication model. Aadhaar e-Sign is purely software-based with no hardware token: the signer authenticates via Aadhaar OTP and the certificate-issuance, key-generation, signing and certificate-archival all happen at the e-Sign Service Provider's secure server, with no client-side cryptographic material at any point. The architectural difference makes e-Sign much more accessible (no hardware procurement, no installation) but DSC more secure against server-side compromise scenarios.
The two mechanisms are best understood as complementary rather than substitutable. Class 3 DSC is suitable for: corporate compliance signing (MCA21, GST companies, ITR-6, EPFO), professional signatory roles (chartered accountants attesting client documents, lawyers filing professional appearances), high-value transaction signing (e-tendering, contract execution), and multi-use enterprise workflows (e-invoicing, bulk document signing). Aadhaar e-Sign is suitable for: individual ITR e-filing, consumer-facing contract execution (insurance proposals, mutual-fund KYC, loan applications), one-off citizen-service transactions, and pilot or low-volume use-cases where the cost and operational overhead of a DSC are not justified. The IT Act 2000 framework explicitly accommodates both within the broader definition of electronic signature, leaving the suitability assessment to be made on a use-case-by-use-case basis by the relying party and the signer.
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.

“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.”
