Country Codes
Overview
The use of country codes is optional in TRX Enterprise â„¢. However once a country code is used in an address it must always be used in an address. The country code is generally a three digit alpha code used to identify a country in a mailing address. These country code correlations must be defined in TRX and that is done in the Country Code Setup Screen.Â
In this screen you simply type the country code and then the country name next to it.
Note: It is highly recommended that you use the USPS country code-naming conventions. They can be found at United States Postal Service website USPS.com.Â
