# DSC for the National Single Window System (NSWS) For approvals on the National Single Window System that ask for a DSC, you need a Class 3 signing DSC in the organisation's name. You add it on the portal under Authorised Signatory Details and attach it to the approval form. We fill and submit the application for you; you do the Aadhaar OTP and video KYC with the Certifying Authority, which issues the certificate on a USB token. Application support is included in the price. ## About us Digital Signature Provider, Udaipur, Rajasthan.

The organisation name on it must match the company's PAN. **Why does NSWS say the organisation name does not match?** NSWS shows the error "Name of Organization as per DSC does not match the Name of Organization as per PAN" when the organisation name on the certificate does not match the name on the company's PAN. The fix is a new organisation DSC issued with the exact name that appears on the PAN. **Why does NSWS say my DSC is already linked?** NSWS allows one certificate against one PAN. If a certificate is already attached to that PAN on the portal, remove or change it there before you add the new one. **How do I add the DSC on NSWS?** Open your profile, go to Authorised Signatory Details, enter the PAN, choose Add Digital Signature Certificate and enter the token PIN. Each new project asks for it again. NSWS uses the emBridge signer to read the certificate from your token. **Does every NSWS approval need a DSC?** No. The certificate can be attached to an approval form. Which approvals ask for it is not published as one list, so the need depends on the particular approval you are filing. **Can I use the same DSC on NSWS and MCA?** Yes, the same Class 3 signing certificate works on both. Register it separately on each portal. **What documents do you need for the organisation DSC?** The PAN and Aadhaar of the person the DSC is for, their mobile and email, a photo for the CA's video KYC, the authorisation letter, the PAN of the person who signs that letter, the company PAN, and the company's GST or registration certificate. The full list is on this page. **Which licences on NSWS need a DSC?** PESO, the petroleum and explosives safety licence portal, runs on NSWS and asks for a DSC. Which other approvals ask for it is not published as one list. --- We are a Registration Authority (RA) for XtraTrust, VSign, eMudhra, Sify, nCODE and PantaSign.
