Filing & Renewal

Digital Signature Certificate (DSC)

Sign filings and tenders securely with a Class 3 DSC.

About Digital Signature Certificate (DSC)

A Digital Signature Certificate (DSC) is the electronic equivalent of a handwritten signature and is legally valid under the Information Technology Act. It is mandatory for a wide range of online filings — MCA/ROC forms, GST returns, income-tax filings, e-tenders, import-export documents and more. Most statutory and business filings today require a Class 3 DSC, which offers the highest level of assurance and is issued on a secure USB token by a licensed Certifying Authority after identity verification. DSCs are typically valid for one to three years. We arrange quick issuance and timely renewal of individual and organisational DSCs, with paperless Aadhaar-based verification where available.

Who needs this
