All about Invoice Reference Number (IRN)

Understanding Invoice Reference Number (IRN) in GST


The GSTN’s most recent recommendations demand the generation of electronic invoices expressly for B2B transactions for companies with annual revenue above Rs. 10 crores. It’s crucial to remember that not all forms of documentation or transactions between companies will be considered for e-invoicing. Currently, in addition to export invoices, the scope of e-invoicing includes invoices, credit notes, and debit notes sent to other registered companies, which are effectively B2B transactions.

The Invoice Reference Number (IRN), which users can retrieve even if it was not initially recorded for an invoice, debit note or credit note, has been made available through the Goods and Services Tax Network, or GSTN. The electronic invoicing system enables GST-registered employees to upload Business-to-Business invoices to the Invoice Registration Portal (IRP)1. The IRP then creates and sends the user a distinct Invoice Reference Number, an electronically signed e-invoice, and a QR code.

What is Invoice Reference Number (IRN)?

The Invoice Reference Number (IRN), often known as a hash, is a distinctive identification created only by the Invoice Registration Portal (IRP) as a component of the e-invoicing system. Within the Goods and Services Tax (GST) scope, this method is intended to standardize and streamline the invoicing procedure. The Invoice Reference Number (IRN) includes several components, including alphabetic letters, numeric digits, and special characters, and has a total length of 64 characters.

The IRN’s primary purpose is to act as a reference point for confirming an invoice’s legitimacy. Any system can determine the legitimacy of an invoice by using this unique alphanumeric code. As a precautionary measure, this verification procedure ensures that a vendor does not submit the same invoice more than once throughout a fiscal year. An invoice Reference Number (IRN) essentially serves as a digital signature for invoices, preventing bogus or duplicate entries.
