Class 3 Digital Signature Certificates issued in MMDA Colony Mogappair 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 MMDA Colony Mogappair 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 MMDA Colony Mogappair 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. 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.
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.

Reading this guide locally — In MMDA Colony Mogappair, on the Mogappair-Mogappair East corridor that passes through MMDA Colony Mogappair.
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.
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.
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.
A Class 3 Combo certificate combines both signing and encryption capabilities in a single token, often through two physically-separate certificate-and-key-pairs stored on the same hardware token. Combo certificates are required for use-cases that involve both signing and confidentiality — notably e-tendering on CPPP, GeM, IREPS and several state e-procurement portals where the bidder signs the bid document with the signing certificate and the procuring entity encrypts feedback to the bidder using the encryption certificate. The ONDC seller-node TLS-mutual-authentication architecture similarly requires a Combo certificate. Combo certificates carry a higher unit cost than signing-only or encryption-only, but the practical convenience of a single token covering both use-cases drives most corporate procurement towards Combo.
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.
The India PKI profile specifies RSA as the primary public-key cryptographic algorithm, with a minimum key-length of 2048 bits for subscriber certificates issued from 01-01-2014 onwards. The CCA's 2022 Cryptographic Guidelines updated the recommended key-length to 3072 bits for new certificates issued from 01-01-2025, with 2048-bit certificates issued before that date remaining valid for their natural validity period. The signature algorithm on subscriber certificates is currently sha256WithRSAEncryption, replacing the sha1WithRSAEncryption that was phased out by 01-01-2016 following the SHA-1 deprecation timeline coordinated internationally by the CA/Browser Forum. Elliptic Curve Cryptography (ECC) certificates under sha256ecdsa are permitted under the India PKI profile but are not yet widely deployed because most Indian government portal validators are RSA-only in practice.
The Subject Distinguished Name on a Class 3 DSC is composed of mandatory and optional attributes specified in the India PKI profile. For an Individual DSC, the mandatory attributes include the subscriber's common name (CN), country (C=IN), state (ST), and may include a serial number to disambiguate same-name subscribers. For an Organisation DSC, additional mandatory attributes include the organisation name (O) and organisation unit (OU). The Subject Alternative Name (SAN) extension under RFC 5280 permits the inclusion of additional identifier types including email address, DNS name, IP address and otherName. The otherName field is used in the India PKI profile to carry sector-specific identifiers such as CDSCO licence number, RBI Certificate of Registration number, FSSAI FBO licence number and similar regulatory identifiers, enabling straight-through authentication on sector portals.
The CCA framework requires that the private key of a Class 3 DSC be stored on a hardware cryptographic token meeting FIPS 140-2 Level 2 (USB token) or Level 3 (HSM) certification under the US National Institute of Standards and Technology's Federal Information Processing Standard. Commonly available USB tokens in the Indian market include eMudhra ePass2003 Auto, Sify SafeNet eToken 5110, Watchdata ProxKey, HYP2003 and the more recent SafeNet eToken FIPS variants. The tokens are accessed via PKCS#11 (the Cryptographic Token Interface Standard under RSA Laboratories' Public-Key Cryptography Standards series, now maintained by OASIS) which provides a standard programming interface for cryptographic operations. The PKCS#11 driver for each token brand is provided by the issuing CA and must be installed before the token can be used on a Windows or macOS workstation.

Digital Signature Certificate — an electronic credential issued by a licensed Certifying Authority under Section 24 of the Information Technology Act 2000 that binds a person's identity to a cryptographic public key. The DSC enables the holder to digitally sign electronic documents such that the signature is legally equivalent to a hand-written signature under Section 5 of the IT Act. Classes of DSC differ by the level of identity verification carried out at issuance.
The highest assurance class of Digital Signature Certificate currently issued in India after Class 1 and Class 2 were retired by the Controller of Certifying Authorities effective 1-Jan-2021. Class 3 mandates physical or biometric / video-based verification of the applicant and is the only class accepted on MCA, GST, IT, EPFO, ESIC, ICEGATE, GeM, CPPP and most government portals. Validity periods are typically 1, 2 or 3 years.
An online electronic signature service under Section 3A of the Information Technology Act 2000, where Aadhaar holders can apply a single-use digital signature to a document by authenticating themselves through Aadhaar OTP. Unlike a Class 3 DSC, e-Sign does not require a hardware token, has no renewal cycle, and the signing key is generated and destroyed on the e-Sign service provider's HSM in the same transaction.
