How to Apply for a Digital Signature Certificate (DSC) Online in India — Complete 2026 Guide

Getting a DSC used to mean visiting a CA office with physical documents. In 2025, the entire process is online — video verification, document submission, and USB token delivery to your door. This guide covers every step, every document, and every cost so you have no surprises.

What is a Digital Signature Certificate?

A Digital Signature Certificate (DSC) is the electronic equivalent of a handwritten signature or a notarised stamp. Issued by a licensed Certifying Authority (CA) under the Information Technology Act 2000, it provides legally binding authentication for online transactions and document signings with the Government of India.

When you sign a document digitally using a DSC, the signature is backed by a cryptographic key stored on a secure USB crypto token (also called a dongle or eToken). This key is unique to you, tamper-proof, and legally equivalent to your physical signature under Indian law.

In simple terms: wherever a government portal asks you to "digitally sign" a form or submission, you need a DSC to do it.

Do You Need a DSC — and Which Type?

02

Submit Documents

Send your PAN, Aadhaar, and photograph digitally. For organisations, include the authorisation letter and board resolution.

03

Complete Video Verification

A 3–5 minute video call with a Certifying Authority representative. No office visit. Done from your phone or laptop.

04

Make Payment

Pay via UPI, NEFT, or bank transfer. Payment triggers immediate processing. No advance payment before document verification.

05

DSC Generated

Your certificate is generated on the CA portal and installed onto a USB crypto token within 2–4 hours of payment (same business day for individuals).

06

USB Token Delivered

The crypto token is dispatched by courier. Mumbai clients receive it same-day or next-day. Other cities receive it within 2–3 business days.

Same-day processing tip: Submit your documents and make payment before 2:00 PM on a business day (Mon–Sat) for same-day issuance of Individual Class 3 certificates. Submissions after 2 PM are typically processed the following morning.

How Delivery and Installation Works

Your DSC is installed on a USB crypto token — a secure hardware device that plugs into your computer's USB port. The token stores your private key in tamper-proof hardware and cannot be copied or extracted.

When you need to sign a document on a government portal, you:

  1. Plug the USB token into your computer
  2. Open the portal and navigate to the signing step
  3. Select your certificate from the list that appears
  4. Enter your token PIN (set during installation)
  5. The document is digitally signed and submitted

Akham provides remote installation assistance for all clients via screen share if needed. Most users complete the driver installation and first signing without any assistance.

The eToken driver software is available for Windows 7, 8, 10, and 11. Mac support is available for most certificate types but requires manual driver configuration — ask us before ordering if you primarily use a Mac.

Renewing Your DSC Before It Expires

DSCs have a fixed validity period (1 or 2 years) and cannot be extended — a new certificate must be issued. If your DSC expires before renewal, you lose access to all portals immediately until the new certificate is issued and installed.

Best practice:

  • Renew at least 30 days before expiry to avoid any gap in portal access
  • Note your expiry date in your calendar or ask your CA to send renewal reminders
  • If you file DSC-dependent documents on a deadline (MCA, GST, Income Tax), renew 60 days before expiry as a safety buffer
📅 Akham automatically sends renewal reminders 30 days and 7 days before your DSC expiry date. You will receive a WhatsApp message — no portal login needed on your end.

Frequently Asked Questions

Can I use my DSC on multiple computers?
Yes. Since the certificate is on a USB token, you can plug it into any Windows or Mac computer that has the eToken driver installed. You are not locked to one device.
What if I lose my USB token?
A lost or damaged token requires a new certificate to be issued (same cost as a fresh DSC). The lost certificate is revoked by the CA and can no longer be used. Report a lost token to your CA immediately.
Is a DSC the same as an Aadhaar OTP-based signature?
No. Aadhaar OTP-based e-signing is a simpler, consumer-grade signature that works for some portals. A DSC is a hardware-backed certificate required by government portals for high-value transactions. Companies must use a DSC — OTP signing is not accepted for MCA filings, e-tenders, or DGFT.
Can a foreign national get a DSC for Indian filings?
Yes. Foreign nationals who are directors, partners, or authorised signatories for Indian companies can apply for a Class 3 DSC using their passport as identity proof. The process takes 2–3 days and costs ₹6,000 for a basic certificate. Akham handles foreign national DSCs regularly.
Which portals accept Class 3 DSC?
Income Tax (incometax.gov.in), MCA21, GSTN, Trademark (ipindia.gov.in), Patent Office, Icegate, NIC e-Procurement portals, NSWS (National Single Window System), and most state government e-tender portals. DGFT portal requires the specific DGFT DSC variant.
