# Currency code

**Element type: Required**

**Enpoints/models used:** [Invoice](https://developer.avalara.com/api-reference/communications/v2/models/Invoice/)

Your integration must provide a way for users to specify the three-character ISO 4217 currency code that should be applied to the invoice. This is done using the `ccycd` field in the [Invoice](https://developer.avalara.com/api-reference/communications/v2/models/Invoice/) model.

**View example**:
