Invoice Reference Number
IRN
64-character unique hash assigned by the IRP to authenticate an e-invoice.
What it means
The IRN is computed by hashing the supplier's GSTIN, invoice number, financial year and document type. Generated by the IRP after validation, the IRN must be quoted on every e-invoice. Without a valid IRN, the invoice is not legally valid under GST e-invoicing rules.
Cancellation of an IRN is permitted only within 24 hours of generation.
