DSC for GeM Portal
Class 3 signing DSC for GeM seller registration and bid submission. What GeM asks for, the price, and how the portal registration works.
Class 3 signing costs ₹1,040 for 1 year, ₹1,200 for 2 years or ₹1,820 for 3 years. The USB e-token is ₹550 more if you do not have one.
Answer
Sellers and service providers on GeM sign bids and contracts with a Class 3 signing DSC, registered under the seller profile on the portal. Foreign sellers must use a DSC. Domestic sellers can also sign with an OTP on their Aadhaar-linked mobile or with an e-Sign, so a DSC is the choice for anyone who bids often or files on more than one portal. We fill and submit the application for you; you do the Aadhaar OTP and video KYC with the Certifying Authority, which issues the certificate. Application support is included in the price.

- We submit, you do the KYC
We file the application with the Certifying Authority. You then confirm your mobile and email with OTPs, do the Aadhaar OTP and video KYC with them, and a final eKYC OTP on your phone approves the application. We assist you at every step.
- Receive token and register on GeM
Get the USB token by courier (or use your own FIPS 140-3 token), then add the certificate to your seller profile on GeM, so the portal can use it when you submit a bid.
Price
If you buy on GeM
- A GeM buyer is an officer of a central or state department, a PSU, an autonomous body, a local body or a constitutional body, at the level of a Deputy Secretary or equivalent. The primary user registers the organisation, and the secondary users are the buyer, the consignee, the DDO and the paying authority.
- GeM's own training material lists the transactions a DSC or eSign can verify: a bid or Rate Agreement published by the buyer, a bid corrigendum, a contract generated by the buyer, a CRAC generated by the consignee, and a bill generated by the buyer.
- The same material answers the question directly. A user can verify with an eSign or a DSC, or carry on using an OTP, so on the buyer side a DSC is a choice and not a mandate.
- The eSign option on GeM is Aadhaar eSign, and GeM's training material points buyers to an eMudhra eSign account for it.
- The DDO who pays a GeM bill signs it in PFMS, not on GeM.

Is a DSC needed for GeM seller registration?
For signing, yes. Foreign sellers must sign with a DSC. Domestic sellers can also sign with an OTP on their Aadhaar-linked mobile or with an e-Sign, and many start that way.
Can a domestic seller use an OTP instead of a DSC?
Yes, GeM lets a domestic seller sign with an OTP or an e-Sign. A DSC is what you take when you bid often, when the OTP is inconvenient, or when you want the same certificate for GST, MCA and the tender portals.
How do I register my DSC on GeM?
Log in to your GeM seller account, open the DSC option under the seller profile settings, and add the certificate from the plugged-in token with its PIN.
What is the difference between the primary and secondary user DSC?
The primary user is the person who owns the seller account, and the certificate is registered in that name. A secondary user is added by the primary user and signs on behalf of the seller.
Can a foreign seller use a foreign DSC?
The certificate has to be issued by a CCA-licensed Certifying Authority in India, because the portal trusts the Indian PKI. We supply the certificate; the identity documents you send decide whether a foreign national or a normal Indian application is the right route.
Can I use the same DSC on GeM and other portals?
Yes. The same Class 3 signing DSC works on GeM, GST, MCA, EPFO and the tender portals. Each portal registers it once, on its own.
Is a new token needed every time?
Only if it is FIPS 140-3. Since 21 September 2026 new certificates cannot go on older FIPS 140-2 tokens, so any token bought before then will not work. A new token is an add-on at checkout.
