There is no document W8-BEN in my country

Hello
I am a game developer in Turkmenistan and I want to sell my games in Epic Games. But in my country there is no document W8-BEN, there is only document [#43]

  1. Will EpicGames accept this document?


If yes, then (1/2 JPG in yellow)

  1. I need information about EpicGames tax office?
  2. Can EpicGames give me a Payment Agreement Contract?

If not, how can I solve it?

Thank you
(the document was quickly translated into google translator just for review)
