Companies and LLPs are mandatorily required to authenticate GST registration and returns using a Class 3 DSC — proprietors and partnerships can use it optionally for added convenience.
As per GST rules, Companies and LLPs must sign GST registration applications and returns using a Class 3 DSC of the authorised signatory — EVC (OTP) is not permitted for these entity types.
GSTR-1, GSTR-3B and annual returns can be authenticated instantly once your DSC is registered on the GST portal — no repeated OTP delays.
Frequent e-way bill generators benefit from DSC-based authentication for smoother, faster portal access during high-volume dispatch periods.
After issuance, we guide you through registering the DSC against your GSTIN on the GST portal so it is ready to use immediately.
