Did not realize until today that finding a Foreign Country Zip Code could be a Headache

I was given the task to order products that had to be shipped to the Dominican Republic. I did not realize until i was going through the order process how time consuming it would be to find the only item i was missing, the postal code. As I could not get in touch with the recipient, I had to search and scroll through some 10 web sites before I found the proper information. Wikipedia had a lot of decent information but for the one I needed.
