Question:

Can the CRM Country_vod__c on the Address_vod__C Object contain picklist Values longer than two Characters?

Answer:

The Country_vod__c Field on the Address_vod__c Object is purposely designed to only use a two-digit code. As a workaround please use the Translation Workbench to make visible changes to the two-digit Country code.
