# Register on the e-Invoicing Portal-IRP

The Invoice Registration Portal (IRP) is the e-Invoicing portal to which you need to send your invoice details. The IRP will then issue a unique Invoice Registration Number (IRN) and QR code for each invoice submitted. All GST registered taxpayers who want to generate e-Invoices should first register on the IRP and create an account.

**Insight:** If your business generates e-Way bills and has already registered the GSTIN on the e-Way Bill (EWB) portal, you can use your EWB portal username and password to log in to the e-Invoicing portal as well. You can skip the steps mentioned below.

**Prerequisite:** To create an account, you need to have your business’s valid GSTIN and the mobile number registered for it with the GST system.

To create an account on the IRP:

*   Go to the [e-Invoicing portal-IRP](https://einvoice1.gst.gov.in/).
*   Click **Registration** and select **Portal Login** from the dropdown.

*   Click **Go**.

*   Once the OTP is verified, you’ll be prompted to enter a **Username** (it should be within 6-15 characters in length) and a **Password**.
*   Re-enter the Password to confirm it.
*   Click **Save**.

Your IRP account will be created and you can log in to it with the set username and password. Once you’ve created an account, you can [enable e-Invoicing in Zoho Books](/in/books/help/e-invoicing/set-up.html#enable) and [connect it to the IRP](/in/books/help/e-invoicing/set-up.html#connect).
