A Class 3 Digital Signature Certificate is an electronic credential issued by a licensed Certifying Authority that lets a person or organisation sign documents and log in to government and tender portals securely. It is widely used for e-tendering and e-procurement, filings on the MCA portal, DGFT applications and other online submissions that need a higher assurance level than basic certificates. The certificate is stored on a hardware token and is valid for a limited period. Directors, bidders, authorised signatories and professionals who file online need one. Our team handles the application, verification and token delivery with a licensed Certifying Authority.

How It Works
Confirm the certificate type
We ask which portals you will use and whether you need a signing certificate, an encryption certificate or both, and whether it will be issued to an individual or in the name of an organisation.
Select validity and token
You choose the validity period offered by the Certifying Authority, and we arrange a compatible hardware token on which the private key is generated and kept, so it cannot be copied as a plain file.
Submit the application and documents
We prepare the application form with the identity and address proofs, the organisation papers and the authorisation letter where applicable, and submit them to the Certifying Authority for verification.
Identity verification
The Certifying Authority verifies the applicant, commonly through a video verification session or another approved method. We brief you on what to keep ready so the session is completed in one attempt.
Certificate issue and token installation
After approval the certificate is issued onto the token. We guide you through driver installation and a test signature, and explain how to set and protect the token password.
Registration on portals and renewal
We help register the DSC on the portal you will use, such as MCA or a tender site, and note the expiry date so you can renew before filings or bids are blocked.
Documents Required
- PAN card of the applicant
- Aadhaar or another valid photo identity proof as accepted by the Certifying Authority
- Recent passport-size photograph
- Address proof, where the Certifying Authority asks for it separately
- Active email address and mobile number of the applicant
- Organisation proof such as incorporation certificate, GST registration or partnership deed, for organisation certificates
- Authorisation letter or board resolution permitting the person to hold the DSC for the organisation
- Attested copies of documents, if the Certifying Authority requires physical verification
Timeline and Fees
Indicative timeline: Indicative range of one to a few working days once documents and verification are completed, though this depends on the Certifying Authority and the verification slot.
Professional fee: The cost depends on the validity period, whether signing only or signing with encryption is chosen, the type of token and whether it is an individual or organisation certificate. Contact our team for a current written quote.
What Can Go Wrong if This Is Missed or Done Incorrectly
- An expired or unregistered DSC can block an MCA filing or a tender submission at the deadline
- Sharing a token and its password lets others sign in your name, and you remain responsible for those signatures
- Incorrect or mismatched details in the application can cause rejection by the Certifying Authority
- Using a certificate whose class is not accepted by a portal can waste time and delay a submission
Frequently Asked Questions
What is a Class 3 DSC and how is it different from other classes?
Classes reflect the level of identity checking and assurance behind the certificate. A Class 3 DSC involves stricter verification and is generally the type required for e-tendering, e-procurement and many government portals. Because requirements on portals change, you should confirm which class the portal you intend to use currently accepts.
Where is a Class 3 DSC used?
Typical uses include submitting bids on e-tender and e-procurement portals, signing forms on the MCA portal, applications to DGFT and other online submissions that need a legally recognised electronic signature. It is also used to sign documents and encrypt bid data where the tender platform requires encryption.
How long is a Class 3 DSC valid?
Certifying Authorities commonly offer validity of one, two or three years, and the choice is yours at the time of application. After expiry the certificate cannot be used and has to be renewed or replaced. We recommend noting the date in advance, as an expired DSC can block a filing or a bid on the deadline.
Why is a USB token needed?
The private key of a Class 3 certificate is generated and stored in a secure hardware token, which makes it difficult to copy and adds protection against misuse. You plug the token in and enter its password whenever you sign. Protect the token and password carefully, since anyone holding both can sign on your behalf.
Do I need to appear in person for verification?
Many Certifying Authorities use video-based verification or other electronic methods instead of an in-person visit, and some accept Aadhaar-based verification. The accepted methods are decided by the Certifying Authority and the applicable guidelines. We confirm the process for your case and prepare you for the session.
What if my DSC is lost, expired or the token stops working?
If the token is lost or the key may be compromised you should have the certificate revoked and apply for a replacement. An expired certificate has to be renewed, and a faulty token may be repaired or replaced, depending on the Certifying Authority. We help with each case so that you can resume filing quickly.
