Well, T-Hub is basically just taking the shipping and billing addresses of each order from the database. So it's not to do with T-Hub or stamps.com as such.

The database stores the two-letter code for the country rather than the country code. So it's a question of figuring out which bit of code is responsible for saving, say, "CA" as part of the shipping address rather than "Canada." And there, I am utterly clueless!
