Secure your Digital Signature Certificate and Director Identification Number—essential credentials for corporate compliance and MCA filings.
Home > Services >Private Limited Company Registration
A Digital Signature Certificate (DSC) and Director Identification Number (DIN) are mandatory prerequisites for incorporating a company and filing compliance forms in India. A DIN is a unique number issued by the Ministry of Corporate Affairs to individuals who want to become company directors, and it remains valid for life. A Class 3 DSC is required for securely and digitally signing all documents and forms submitted on the MCA portal. Calcutta Corporate facilitates quick and hassle-free issuance of both DSCs and DINs, ensuring you are fully equipped for all your corporate and tax compliance needs.
A valid Class 3 DSC and an approved DIN are legally required to file incorporation and compliance forms on the MCA portal.
Your DIN is permanently tied to you as an individual, not the company, meaning it remains the same for your entire life even if you change companies.
A DSC ensures that all electronically transmitted documents are highly secure, authentic, and protected from tampering or unauthorized access.
Beyond MCA filings, a Class 3 DSC can also be utilized for Income Tax returns, GST filings, and e-tenders.
Digital signatures eliminate the need for physical paperwork, significantly speeding up document authorization and regulatory filings.
With the modernized digital KYC process, DSCs and DINs can be obtained rapidly, minimizing delays in your business setup.
We securely gather your required identity and address proof documents, including your PAN and Aadhaar.
We file the necessary forms (such as DIR-3 or SPICe+) with the MCA to apply for your Director Identification Number.
You complete a simple online video and mobile OTP verification to securely authenticate your identity for the DSC issuance.
Upon approval, your digital certificate is downloaded into a highly secure USB token for physical use.
We assist in registering and associating your new DSC against your DIN or PAN as a business user on the MCA V3 portal.
We help ensure your credentials remain active, handling mandatory updates like routine DIR-3 KYC filings.
Our team will guide you through every step — from documentation to final registration. Most services are completed faster than you expect.
