Http://en.wikipedia.org/wiki/Belgrade Belgrade is the capital of Serbia. On this Wikipedia website on the right hand side a little ways down it lists the postal code as 11000. I don't know what you'll do with that, but I hope that helps.

Go to the website maintained by the Post Office there and follow the directions.
