Why verify GSTIN before you sign
Incorrect GSTINs create invoice mismatches, failed e-way bills, and reconciliation noise. Pulling taxpayer details at onboarding or just before signing reduces downstream corrections.
What IG E-Sign exposes
With a complete company profile, your account can look up GSTIN details, filing preferences, and return status through the dashboard or REST API. GST usage is metered separately from signing quotas.
- Get GSTIN details for any valid GSTIN within quota
- Fetch preferences for a financial year
- View return status filters such as R1, R3B, or R9
- Print E-way bill and e-invoice (IRN) PDFs with NIC portal credentials
- Use the same API key as signing services
Pairing GST checks with PDF signing
A common pattern is: verify the counterparty GSTIN, generate the invoice PDF, sign with PFX or Class 3 USB DSC, then pull E-way bill or e-invoice PDFs when you need the official printouts. One platform keeps audit trails for lookup, print, and signature events.
