A Digital Signature Certificate (DSC) is a secure electronic equivalent of a physical signature used to digitally sign documents, access government portals, and encrypt electronic communications. Issued by a licensed Certifying Authority (CA) approved by the Controller of Certifying Authorities (CCA), a DSC verifies the identity of the signer while securely storing personal credentials.
In India, a DSC is mandatory for GST filings, income-tax filings, EPFO compliances, MCA/ROC filings, e-procurement, and government tenders. The application process is fully online, uses multi-factor authentication, and verification is typically completed within minutes, after which the certificate can be downloaded or issued in a secure USB token.
Types of Digital Signature Certificates in India
Earlier, DSCs in India were classified as Class 1, Class 2, and Class 3. However, with effect from 1 January 2021, the CCA simplified the framework, and only Class 3 Digital Signature Certificates are issued and accepted today.
Class 1 DSC
Level: Basic, low assurance
Verification:Email ID and name only
Class 1 Digital Signature Certificates were introduced in the early stages of India’s digital authentication framework. The verification relied only on the applicant’s email ID and name, making it unsuitable for company registration in India. Because of this limited authentication, Class 1 DSCs were never considered suitable for regulatory filings, financial transactions, or legally binding documentation.
Status: No longer valid for official or legal use
Class 1 DSCs have been discontinued and are no longer recognised for any statutory, legal, or government-related purpose in India.
Class 2 DSC
Level:Moderate assurance
Verification:Identity validated against trusted databases
Class 2 Digital Signature Certificates offered a higher level of authentication than Class 1. Certifying Authorities verified the applicant’s identity against government and trusted databases, which made these certificates acceptable for statutory filings and compliance work.
Earlier Uses:
- Income-tax return filings
- GST return filings
- MCA and ROC filings
For many years, Class 2 DSCs were widely used by professionals, business owners, and authorised signatories for government compliance.
Status: Issuance stopped from 1 January 2021
As per updated guidelines issued by the Controller of Certifying Authorities (CCA), the issuance of Class 2 DSCs was discontinued from 1 January 2021. Existing certificates were allowed to expire naturally and could not be renewed. This led to the transition towards a single, higher-security standard — Class 3 DSC.
Class 3 DSC (Currently in Use)
Level: Highest and only valid DSC class in India
Today, Class 3 is the only legally recognised Digital Signature Certificate for individuals, businesses, and organisations. If you are searching for how to get valid digital signature certificate, this is the class you must apply for.
Verification Process
The issuance of a Class 3 DSC involves strict identity verification and multi-layer authentication:
- Aadhaar-based eKYC authentication
- Live video verification of the applicant
- PAN validation and address proof verification
- Verification by a licensed Certifying Authority approved by the CCA
This robust process ensures that the DSC is legally admissible and highly secure for official transactions.
Security
Class 3 DSCs are issued on a FIPS 140-2 Level 2 certified USB crypto token. This hardware token:
- Prevents copying or duplication of the signature key
- Protects against malware and unauthorised access
- Ensures that the private key never leaves the secure device
Mandatory Uses
A Class 3 DSC is compulsory for:
- All MCA and ROC filings
- GST and Income-tax return filings
- E-tendering, e-procurement, and e-auctions
- Intellectual Property filings (trademark, patent, copyright)
- Digitally signing legally binding agreements and contracts
For businesses wondering how to get digital signature certificate for GST, a Class 3 DSC is mandatory for authorised signatories on the GST portal.
