The Goods and Services Tax Identification Number (GSTIN) is a 15-digit unique identifier assigned to each business registered under the GST framework in India. GSTIN verification validates these numbers in real-time, enabling businesses to prevent fraud and streamline KYC, vendor onboarding, lending, and insurance workflows.

Best practices

Follow these recommendations to optimise your GSTIN verification implementation and ensure reliable business validation:
  • Regular verification: Re-verify GSTINs periodically as registration status can change over time.
  • Cross-reference data: Use GSTIN verification alongside other KYB verification methods for comprehensive business validation.
  • Monitor status changes: Check for GSTIN status changes before processing transactions to avoid compliance issues.
  • Maintain records: Store verification records for compliance and audit purposes as required by regulatory frameworks.
  • Validate format: Ensure GSTIN follows the correct 15-digit format before making API calls to avoid unnecessary requests.
  • Handle errors gracefully: Implement robust error handling for invalid, inactive, or temporarily unavailable GSTIN data.
  • Cache results: Store verification results temporarily to reduce API calls for repeated checks of the same GSTIN.
  • Set timeouts: Configure appropriate API timeout values to handle network latency and server response delays.
