Can I use a country code in the Zip Code field for international transactions?

Overview

 Will the Zip Code field accept a country code for international orders?

Environment

Avalara AvaTax / API

Resolution

Avalara AvaTax requires the country code be set in the Country Code field where international countries are concerned.

If the country is either the United States or Canada, you can leave the field blank. 

For international countries, you are required to set the proper ISO Code and it also must be in the Country Code field.
