What is the limit of IRN and QR Code generation in the invoice

The limit of IRN (Invoice Reference Number) and QR Code generation in an invoice varies depending on the country's tax regulations and the specific invoicing system being used. However, here are some general guidelines: IRN: - In India, under the GST regime, an IRN is generated for each invoice, and there is no specific limit on the number of IRNs that can be generated. - However, it is recommended to generate a unique IRN for each invoice to avoid any potential issues with tax authorities. QR Code: - In India, the GST Council has mandated the use of QR codes on invoices for B2B transactions above ₹50,000. - There is no specific limit on the number of QR codes that can be generated, but each QR code should be unique and linked to a specific invoice. Please note that these limits may change based on regulatory updates or specific invoicing system requirements.
