- This shall be unique to each invoice and hence be the unique identity for each invoice for the entire financial year in the entire GST System for a taxpayer.
20. Explain in detail about IRN
- Each Invoice uploaded by the tax payer will get the unique number called as Invoice Reference Number (IRN).
- IRN is of 64 Characters length.
- This IRN is unique number in the GST system, irrespective of tax payer, financial year and document type.
- IRN is generated by the e-invoice system once the tax payer uploads the invoice details.
- IRN is generated using the computer algorithm (RSA256) based on the combination of the Supplier GSTIN, Document Type, Document Number and year of the Invoice (Financial Year).
- IRN is hash of Supplier GSTIN + Fin. Year + Doc Type + Doc Number.
- Financial Year is calculated based on the date of invoice. That is, the financial year starts with 1st April and ends on 31st March and represented as YYYY-YY. If the date is 03.01.2020, the financial year is 2019-20.
- Document types are INV for Invoice, CRN for Credit Note, DBN for Debit Note.
- Document Number is a number printed on the Document, being issued to the purchaser, and it is to be of maximum of 16 alphanumeric and / -.
- Document number should not be starting with 0, / and -. Also, alphabets in document number should not have alphabets in lower cases. If so, then request is rejected.
- For example, tax payer with 01AAAAA9999A19N has issued the Invoice with Number ABC01234 on 12.12.2019 to his supplier, string used for hashing is 01AAAAA9999A19N2019-20INVABC01234.
