Thank you for asking questions about that Samsung Streaming Blu-ray Player. I personally own a model very similar to the one you are interested in, and I love it.
ZA is used by Samsung to notate the country code. The official model number will always include the country of intended use like the one we offer here. Any model that is made to be used outside of the United States would have a different code in the ending.
Essentially the two models notated as H6500/ZA or BD-H6500 are the same exact item as long as they are both sold by Samsung authorized retailers within the United States.
I hope that helps answer your questions!
