In Zoho Inventory, you can add serial numbers to your items in two ways:

> **Prerequisite:** To add serial numbers, you must first ensure that the item is inventory tracked.

##### While creating a new item

*   Click the **+** icon next to **Items**.
*   Fill out the basic details of the product in the **New Item** page.
*   Check the box next to **Track Inventory** and enter the opening stock details.
*   Click the option that says **Track Serial Number** under **Advanced Inventory Tracking** and enter the serial numbers for the specified opening stock.
*   Hit **Save** to successfully add new serial numbers for that item.

##### While recording a new purchase bill

*   Open a **New Bill** page by clicking **+** icon next to Bills.
*   Upon adding a serial number tracked item, the **Add serial number** option becomes available in the _Quantity_ section.
*   Click on it and enter the serial numbers for the specified quantity.
*   Click **Save** to successfully add new serial numbers for that item.

> **Note:** The Bill must be between **Open** and **Paid** status for the serial numbers to be available for other outbound transactions.
