USPS Invalid Country Code


Recommended Posts

I have searched and searched. I have the account and it has been moved to production server. USPS module works with international customer address but for domestic i get invalid country code.


Anyone know the resolution? :(

I am having the same problem, however, I started with a 'missing country' error. Looking at the usps.php file, I found the list of countries at the bottom of the file and noticed that 'US' => "United States" (or whatever it should be) was missing, so I added it. After that I recieved the invalid country error.
