USPS module not shipping to Korea, Republic of

I am using the latest USPS module for international shipping, and I am unable to ship to an address in Kyonggi-do, Korea, Republic of (South Korea). No shipping methods are available. All other international countries are working fine. I checked my country codes and my setup for our International zone, and Korea, Republic of is added there as shipping to all zones. Also, I have the correct type of shipping for this country (Express Mail International). According to the USPS website, their rules state:

Service is available only to the provinces comprising the Republic of Korea, i.e., provinces south of the 38th parallel of latitude.
The following is a list of the provinces comprising the Republic of Korea:

Cheju-do
Cholla-namdo
Cholla-pukto
Ch’ungch’ong-namdo
Ch’ungch’ong-pukto
*Kangwon-do
*Kyonggi-do
Kyongsang-namdo
Kyongsang-pukto

The provinces marked with the asterisk (*) are divided by the 38th parallel of latitude, and it is the responsibility of the mailers to determine that the post offices to which their parcels are addressed are located south of the 38th parallel. Mail addressed to offices north of the 38th parallel will not be forwarded to destination but will be treated as undeliverable.

However, this address is south of the 38th parallel and should be deliverable. Has anyone else had this issue, or have ideas on how to resolve it?

Thanks!

Do you have an actual address information for one that is not working and the weight you are trying to ship? (Street Address is not important)

Just an update, I did try it with another province that is all all south of the 38th parallel and not a divided one (above & below 38th parallel) and it still is not working.

Ajeh:

Yes, address is Uijungbu-si, Kyunggi-do, post code 480-010 - weight is under 66lbs. (max weight on express intl)

What happens if you edit your Country for ISO Code: KR and change the country to:
South Korea (Korea, Republic of)

NOTE: this change will be working with the old country setting of:
Korea, Republic of

in the next release for USPS ...

NOTE: you can try the USPS in this thread on post #6 as it manages things a little better on matching USPS's idea of country names vs the proper ISO Code names:

I think that worked! (it does on my test one anyway, contacting the customer to retry it as well) - THANK YOU!
