We do quite a bit of international sales and are making extensive use of the international address lookup and validation system that's built into FC. By and large, it's been really helpful for folks. That said, we are starting to accumulate a list of strange behaviors, incorrect validations, excess information requests, etc.
• The UK no longer requires that counties be included in the address, but the system includes them by default. This adds a 6th line to the address, which mucks up our import to USPS because only 5 lines are allowed.
• Ecuador and UAE (among many others) don't use postal codes but the system requires the customer to enter one anyways, which leads people to abandon check out.
• Some valid Dutch postal codes won't validate, making it impossible for some folks to successfully check out.
What is the proper channel for feeding these bug and fix requests to whoever manages the international validation system? We'd be happy to help knock them down one a time to improve the system for everyone. Thanks!
