# Fill product with serial number

## Setup

To make it work, follow these two steps:

1. **Upload/Add Serial Numbers**: Navigate to the App admin > Serial Numbers. For each serial number, enter the associated **SKU** of the product. Ensure that the product exists on Shopify with the specific SKU linked to the serial number.
2. **Enable Product Display on Serial Number Validation**: In the App admin, go to Forms > Select the form > Settings > General. Enable the option "Show product when validating a serial number".

Once the above setup is complete, you can test it on the frontend form. Navigate to the form and enter a serial number that has an associated SKU. The product information will be displayed, and the product field will be automatically prefilled.
