# Item description

Source: https://developer.avalara.com/marketplace-integration-guide/designing/item-description/

**Endpoints/models used:** [ItemModel](https://developer.avalara.com/api-reference/avatax/rest/v2/models/ItemModel/)

Your UI should include a human-readable `description` for each `itemCode` in your product catalog. Note that human readability is especially important if you're participating in [Avalara Streamlined Sales Tax (SST)](https://www.avalara.com/us/en/products/sales-and-use-tax/streamlined-sales-tax.html). Item descriptions can be a maximum of 255 characters in length and are used in AvaTax returns. Example descriptions include product names and product descriptions. Refer to the [ItemModel](https://developer.avalara.com/api-reference/avatax/rest/v2/models/ItemModel/) in the AvaTax API for more information.
