How to recognize the profile

Do not rely on the file extension alone. Inspect the root namespace, customization/profile identifiers, version values and authority-specific envelope.

  • 64-character IRN
  • AckNo
  • SignedQRCode
  • GSTIN

Production validation stack

  1. 1
    JSON schema

    Confirm that the document is well formed and structurally compatible with the intended GST IRN syntax.

  2. 2
    GSTIN and master data

    Apply semantic and business-rule checks rather than accepting a file merely because it parses.

  3. 3
    Business rules

    Validate currencies, countries, tax categories, units, payment means and other controlled values against the correct release.

  4. 4
    IRP response and QR signature

    Apply the national, network or authority restrictions that narrow the base syntax.

EInvoiceLab’s browser tools provide detection, inspection and technical preflight. A profile is only production-valid after applying the correct official artefacts and obtaining the required network or authority outcome.

Questions people ask

What is GST IRN?

India’s Invoice Registration Portal model producing a signed invoice, Invoice Reference Number and QR code from prescribed JSON payloads.

How is GST IRN validated?

A production check normally applies JSON schema, GSTIN and master data, Business rules, IRP response and QR signature. Local browser preflight cannot replace the official validation artefacts or authority outcome.

Which version should I use?

The current research note is: Verify current schema and turnover applicability on the official IRP. Confirm release notes at the official source before production deployment.
