About Digital Signature Certificate

Digital Signature Certificates are used for GST, MCA, Income Tax, Tender submissions, EPFO filings, and more. It is legally binding. As a means of identification and verification, the certifying authority issues a USB e-Token (secure digital key). The signatures are encoded using public keys and stored electronically. A digital signature certificate (DSC) includes information about the user name, pin code, nationality, email address, date of certificate issued, and the name of the certifying authority.

Frequently Asked Questions (FAQ)

You may purchase digital signature certificates with one, two, or three years of validity. (The regulating authority, the Controller of Certifying Authority CCA, controls this validity. You cannot buy a DSC with a validity period of less than one year or greater than three years.)

The Digital Signature is required during the following times:


  • While Incorporating companies like Public Limited Company, Private Limited Company, Limited Liability Partnership, or One Person Company.

The certifying authorities issue three types of Digital Signature certificates. These include:

  1. Class 1 DSC

The Class 1 DSC is issued to individual subscribers, and it confirms that the user’s name and email address are stored in the certifying authority’s database.

  1. Class 2 DSC 

Class 2 DSCs are granted to company directors and signing authorities for electronic filing with the Registrar of Companies (ROC). Individuals who would sign manual documents while filing returns with the ROC must use a Class 2 digital signature. However, starting on January 1, 2021, the Controller of Certifying Authority has directed that Class 2 DSC be discontinued. In place of Class 2 DSC, Class 3 DSC will be issued. 

  1. Class 3 DSC 

A Class 3 Digital Signature Certificate is granted to company directors/authorised signatories, professionals, and others for digitally signing documents. To participate in the online bids, suppliers must also have a Class 3 DSC.

To issue a Digital Signature, there is no need for physical verification.
