What are the state codes and how do I find them?
 

in the admin > management > state area; If I want to add a state I need to have a state code; where do I find those?

For the US? Those are the standard US state abbreviations.

what about foreign countries like: australia, uk, africa, etc... how can I find the codes for those?

Google is your friend :)
