How to Check Digital Signature Validity and Expiry Date?

Every Digital Signature Certificate (DSC) issued in India comes with a validity period — usually 1, 2 or 3 years. After expiry, it becomes invalid and needs to be renewed to continue using it on government portals like MCA, GST, DGFT, Income Tax, or EPFO.

If you’re unsure whether your Digital Signature is still valid or expired, you can easily check its validity and expiry date using the following simple methods.

Method 1: Check Validity Using Your Computer

Follow these steps to check the validity and expiry date of your DSC from your Windows computer:

Insert your USB token (ePass, WatchData, ProxKey, etc.) into your computer.

Open the token management tool (for example: ePass 2003, WD ProxKey, or Safenet).

Click on “Certificates” or “My Certificates” section.

Select your Digital Signature Certificate.

You’ll see details such as:

Certificate Holder Name
Issuer (CA Provider)
Validity Period
Expiry Date

Tip: If your DSC is expiring soon, renew it before the expiry date to avoid disruption in your filings.

Method 2: Check Validity Using Browser (Google Chrome / Firefox)

You can also check DSC details directly from your browser:

Open your browser and go to Settings -> Privacy & Security -> Certificates -> View Certificates.

Insert your USB token.

Your DSC will appear under Personal Certificates.

Double-click on it to view the Validity Period and Expiry Date.

This method is quick and works for all types of DSCs issued by eMudhra, VSign, PantaSign, Capricorn, and SpeedSign.
