Can I send the country code in the zip field for international transactions?

Overview

Inquiry: Will the zip code field accept a country code for international orders.

Environment

Avalara AvaTax / API

Resolution

Avalara AvaTax requires the country code be sent in the country code field where Internation Countries are concerned. If the Country is either the US or Canada you are able to leave the field blank, this is not the case with International Countries. You are required to sent the proper ISO Code as well it must be in the country code field.
