I do not know if it is still the same way but when I took it in China the address did not matter because I had to pick up the GMAT score report myself at the school. So the address only works to establish your own ID: when you call ETS, you will be asked to identify yourself by saying your DOB, address, etc.
Joice gave you most of it. If you do not know how to do some of the names (such as Chaoyang), just use Pinyin.
