# Item/commodity code

**Element type:** Required

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

Your UI must include a method for allowing users to specify an item code that can be passed to AvaTax to associate a tax code. This code represents the product/service/SKU identifier from the source system. Item codes must be unique strings and can have a maximum length of 50 characters. Possible item codes include product SKUs, IDs, and names. Refer to the [ItemModel](https://developer.avalara.com/api-reference/avatax/rest/v2/models/ItemModel/) in the AvaTax API for more information.
