While the USPS January 17, 2016 K8 shipping module released today at:

I have discovered USPS has changed a few things ...

The issues are with some country names.

USPS has always had their own, special sort of way of spelling countries and we try to provide a translation list for these quirks built into the USPS shipping module.

Unfortunately, I am starting to spot some oddities on some of the more obscure countries ...

Hence it would be of help if anyone else catches a country that isn't working or some other quirk and post in this support thread.

If you are reporting a Country issue, please provide enough information about what exact shipping address you are using.

The best help is to turn on the Debug Log and Zip the log created when attempting the quote and attach it to your post.
