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 Status: No longer valid for official or legal use Class 1 DSCs have been discontinued and are no longer recognised for any statutory, legal, or government-related purpose in India.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.
