What you really want is the definition defined here:
https://www.zen-cart.com/content.php...ne-definitions

These definitions can be pasted in your Tools ... Install SQL Patches ... and then you will see them in the Locations / Taxes ... Zones Definitions ...

Next, try using that as the Zone and see if the other countries outside of the US are now getting the shipping showing ... The US is the only country that will not show on that shipping module ...
