IRP

Central component of India's GST e-invoicing system, a clearance model.

Definition

The IRP is the mandatory clearance gateway of GST e-invoicing. It checks the GSTIN, uniqueness and schema, computes the IRN hash, digitally signs the invoice and returns IRN + QrCode + Acknowledgement Number. NIC runs the primary IRP (einvoice1.gst.gov.in); several accredited private IRPs exist since 2023.

Origin

Defined by the GST Council and notified by the CBIC (Notification 13/2020 – Central Tax), operated under the GSTN and the National Informatics Centre (NIC).

Example in context

POST /eivital/v1.04/invoice → response: <AckNo>112010...</AckNo><Irn>HASH-BASE64</Irn><SignedQRCode>JWS...</SignedQRCode>
